Class jdbcCallableStatement

    java.lang.Object
      org.hsqldb.jdbc.jdbcStatement
          org.hsqldb.jdbc.jdbcPreparedStatement
              org.hsqldb.jdbc.jdbcCallableStatement

All Implemented Interfaces:
  java.sql.CallableStatement, java.sql.PreparedStatement, java.sql.Statement

public class jdbcCallableStatement
extends jdbcPreparedStatement
implements java.sql.CallableStatement

The interface used to execute SQL stored procedures. The JDBC API provides a stored procedure SQL escape syntax that allows stored procedures to be called in a standard way for all RDBMSs. This escape syntax has one form that includes a result parameter and one that does not. If used, the result parameter must be registered as an OUT parameter. The other parameters can be used for input, output or both. Parameters are referred to sequentially, by number, with the first parameter being 1.

       {?= call <procedure-name>[<arg1>,<arg2>, ...]}
       {call <procedure-name>[<arg1>,<arg2>, ...]}

IN parameter values are set using the `set` methods inherited from `PreparedStatement`. The type of all OUT parameters must be registered prior to executing the stored procedure; their values are retrieved after execution via the `get` methods provided here.

A `CallableStatement` can return one `ResultSet` object or multiple `ResultSet` objects. Multiple `ResultSet` objects are handled using operations inherited from `Statement`.

For maximum portability, a call's `ResultSet` objects and update counts should be processed prior to getting the values of output parameters.

### HSQLDB-Specific Information:

Since 1.7.2, the JDBC CallableStatement interface implementation has been broken out of the jdbcPreparedStatement class into this one.

With 1.7.2, some of the previously unsupported features of this interface are now supported, such as the parameterName-based setter methods.

More importantly, jdbcCallableStatement objects are now backed by a true compiled parameteric representation. Hence, there are now significant performance gains to be had by using a CallableStatement object instead of a Statement object, if a short-running CALL statement is to be executed more than a small number of times. Moreover, the recent work lays the foundation for work in a subsequenct release to support CallableStatement OUT and IN OUT style parameters, as well as the generation and retrieval of multiple results in response to the execution of a CallableStatement object.

For a more in-depth discussion of performance issues regarding 1.7.2 prepared and callable statement objects, please see overview section of `jdbcPreparedStatment`.

As with many DBMS, HSQLDB support for stored procedures is not provided in a completely standard fashion.

Beyond the XOpen/ODBC extended scalar functions, stored procedures are typically supported in ways that vary greatly from one DBMS implementation to the next. So, it is almost guaranteed that the code for a stored procedure written under a specific DBMS product will not work without at least some modification in the context of another vendor's product or even across a single vendor's product lines. Moving stored procedures from one DBMS product line to another almost invariably involves complex porting issues and often may not be possible at all. Be warned.

At present, HSQLDB stored procedures map directly onto the methods of compiled Java classes found on the classpath of the engine at runtime. This is done in a non-standard but fairly efficient way by issuing a class grant (and possibly method aliases) of the form:

     GRANT ALL ON CLASS "package.class" TO [<user-name> | PUBLIC]
     CREATE ALIAS <call-alias> FOR "package.class.method" -- optional

This has the effect of allowing the specified user(s) to access the set of uniquely named public static methods of the specified class, in either the role of SQL functions or stored procedures. For example:

     CONNECT <admin-user> PASSWORD <admin-user-password>;
     GRANT ALL ON CLASS "org.myorg.MyClass" TO PUBLIC;
     CREATE ALIAS sp_my_method FOR "org.myorg.MyClass.myMethod"
     CONNECT <any-user> PASSWORD <any-user-password>;
     SELECT "org.myorg.MyClass.myMethod"(column_1) FROM table_1;
     SELECT sp_my_method(column_1) FROM table_1;
     CALL 2 + "org.myorg.MyClass.myMethod"(-5);
     CALL 2 + sp_my_method(-5);

Please note the use of the term "uniquely named" above. Including 1.7.2, no support is provided to deterministically resolve overloaded method names, and there can be issues with inherited methods as well; currently, it is strongly recommended that developers creating stored procedure library classes for HSQLDB simply avoid designs such that SQL stored procedure calls attempt to resolve to:

1. inherited public static methods
2. overloaded public static methods

Also, please note that `OUT` and `IN OUT` parameters are not yet supported due to some unresolved low level support issues.

Including 1.7.2, the HSQLDB stored procedure call mechanism is essentially a thin wrap of the HSQLDB SQL function call mechanism, extended to include the more general HSQLDB SQL expression evaluation mechanism. In addition to stored procedure calls that resolve directly to Java method invocations, the extention provides the ability to evaluate simple SQL expressions, possibly containing Java method invocations, outside any `INSERT`, `UPDATE`, `DELETE` or `SELECT` statement context.

With HSQLDB, executing a `CALL` statement that produces an opaque (OTHER) or known scalar object reference has virtually the same effect as:

     CREATE TABLE DUAL (dummy VARCHAR);
     INSERT INTO DUAL VALUES(NULL);
     SELECT <simple-expression> FROM DUAL;

As a transitional measure, HSQLDB provides the ability to materialize a general result set in response to stored procedure execution. In this case, the stored procedure's Java method descriptor must specify a return type of java.lang.Object for external use (although at any point in the devlopment cycle, other, proprietary return types may accepted internally for engine development purposes). When HSQLDB detects that the runtime class of the resulting Object is elligible, an automatic internal unwrapping is performed to correctly expose the underlying result set to the client, whether local or remote.

Additionally, HSQLDB automatically detects if java.sql.Connection is the class of the first argument of any underlying Java method(s). If so, then the engine transparently supplies the internal Connection object corresponding to the Session executing the call, adjusting the positions of other arguments to suite the SQL context.

The features above are not intended to be permanent. Rather, the intention is to offer more general and powerful mechanisms in a future release; it is recommend to use them only as a temporary convenience.

For instance, one might be well advised to future-proof by writing HSQLDB-specific adapter methods that in turn call the real logic of an underlying generalized JDBC stored procedure library.

Here is a very simple example of an HSQLDB stored procedure generating a user-defined result set:

     package mypackage;

     class MyClass {

          public static Object mySp(Connection conn) throws SQLException {
              return conn.createStatement().executeQuery("select * from my_table");
          }
     }

Here is a refinement demonstrating no more than the bare essence of the idea behind a more portable style:

     package mypackage;

     import java.sql.ResultSet;
     import java.sql.SQLException;

     class MyLibraryClass {

          public static ResultSet mySp() throws SQLException {
              return ctx.getConnection().createStatement().executeQuery("select * from my_table");
          }
     }

     //--

     package myadaptorpackage;

     import java.sql.Connection;
     import java.sql.SQLException;

     class MyAdaptorClass {

          public static Object mySp(Connection conn) throws SQLException {
              MyLibraryClass.getCtx().setConnection(conn);
              return MyLibraryClass.mySp();
          }
     }

In a future release, it is intended to provided some new features that will support writing fairly portable JDBC-based stored procedure code:

- Support for the "jdbc:default:connection" standard database connection url.

- A well-defined specification of the behaviour of the HSQLDB execution stack under stored procedure calls.

- A well-defined, pure JDBC specification for generating multiple results from HSQLDB stored procedures for client retrieval.

Constructor Detail

### jdbcCallableStatement

    public jdbcCallableStatement(jdbcConnection c,
                                 java.lang.String sql,
                                 int type)
                          throws org.hsqldb.HsqlException,
                                 java.sql.SQLException

  Constructs a new jdbcCallableStatement with the specified connection and result type.

Parameters:
  `c` - the connection on which this statement will execute
  `sql` - the SQL statement this object represents
  `type` - the type of result this statement will produce
Throws:
  `org.hsqldb.HsqlException` - if the statement is not accepted by the database
  `java.sql.SQLException` - if preprocessing by driver fails

Method Detail

### close

    public void close()
               throws java.sql.SQLException

  Does the specialized work required to free this object's resources and that of it's parent classes.

  Specified by:
    `close` in interface `java.sql.Statement`
  Overrides:
    `close` in class `jdbcPreparedStatement`
  Throws:
    `java.sql.SQLException` - if a database access error occurs

### registerOutParameter

    public void registerOutParameter(int parameterIndex,
                                     int sqlType)
                              throws java.sql.SQLException

  Registers the OUT parameter in ordinal position `parameterIndex` to the JDBC type `sqlType`. All OUT parameters must be registered before a stored procedure is executed.

  The JDBC type specified by `sqlType` for an OUT parameter determines the Java type that must be used in the `get` method to read the value of that parameter.

  If the JDBC type expected to be returned to this output parameter is specific to this particular database, `sqlType` should be `java.sql.Types.OTHER`. The method `getObject(int)` retrieves the value.

  ### HSQLDB-Specific Information:

  HSQLDB 1.7.2 does not support this feature.

  Calling this method always throws an `SQLException`.

  Specified by:
    `registerOutParameter` in interface `java.sql.CallableStatement`
  Parameters:
    `parameterIndex` - the first parameter is 1, the second is 2, and so on
    `sqlType` - the JDBC type code defined by `java.sql.Types`. If the parameter is of JDBC type `NUMERIC` or `DECIMAL`, the version of `registerOutParameter` that accepts a scale value should be used.
  Throws:
    `java.sql.SQLException` - if a database access error occurs
  See Also:
    `Types`

### registerOutParameter

    public void registerOutParameter(int parameterIndex,
                                     int sqlType,
                                     int scale)
                              throws java.sql.SQLException

  Registers the parameter in ordinal position `parameterIndex` to be of JDBC type `sqlType`. This method must be called before a stored procedure is executed.

  The JDBC type specified by `sqlType` for an OUT parameter determines the Java type that must be used in the `get` method to read the value of that parameter.

  This version of `registerOutParameter` should be used when the parameter is of JDBC type `NUMERIC` or `DECIMAL`.

  ### HSQLDB-Specific Information:

  HSQLDB 1.7.2 does not support this feature.

  Calling this method always throws an `SQLException`.

  Specified by:
    `registerOutParameter` in interface `java.sql.CallableStatement`
  Parameters:
    `parameterIndex` - the first parameter is 1, the second is 2, and so on
    `sqlType` - the SQL type code defined by `java.sql.Types`.
    `scale` - the desired number of digits to the right of the decimal point. It must be greater than or equal to zero.
  Throws:
    `java.sql.SQLException` - if a database access error occurs
  See Also:
    `Types`

### wasNull

    public boolean wasNull()
                    throws java.sql.SQLException

  Retrieves whether the last OUT parameter read had the value of SQL `NULL`. Note that this method should be called only after calling a getter method; otherwise, there is no value to use in determining whether it is `null` or not.

  ### HSQLDB-Specific Information:

  HSQLDB 1.7.2 does not support this feature.

  Calling this method always throws an `SQLException`.

  Specified by:
    `wasNull` in interface `java.sql.CallableStatement`
  Returns:
    `true` if the last parameter read was SQL `NULL`; `false` otherwise
  Throws:
    `java.sql.SQLException` - if a database access error occurs

### getString

    public java.lang.String getString(int parameterIndex)
                               throws java.sql.SQLException

  Retrieves the value of the designated JDBC `CHAR`, `VARCHAR`, or `LONGVARCHAR` parameter as a `String` in the Java programming language.

  For the fixed-length type JDBC `CHAR`, the `String` object returned has exactly the same value the (JDBC4 clarification:) SQL `CHAR` value had in the database, including any padding added by the database.

  ### HSQLDB-Specific Information:

  HSQLDB 1.7.2 does not support this feature.

  Calling this method always throws an `SQLException`.

  Specified by:
    `getString` in interface `java.sql.CallableStatement`
  Parameters:
    `parameterIndex` - the first parameter is 1, the second is 2, and so on
  Returns:
    the parameter value. If the value is SQL `NULL`, the result is `null`.
  Throws:
    `java.sql.SQLException` - if a database access error occurs
  See Also:
    `setString(java.lang.String, java.lang.String)`

                              throws java.sql.SQLException

  Registers the designated output parameter. This version of the method `registerOutParameter` should be used for a user-defined or `REF` output parameter. Examples of user-defined types include: `STRUCT`, `DISTINCT`, `JAVA_OBJECT`, and named array types.

  (JDBC4 claraification:) All OUT parameters must be registered before a stored procedure is executed.

  For a user-defined parameter, the fully-qualified SQL type name of the parameter should also be given, while a `REF` parameter requires that the fully-qualified type name of the referenced type be given. A JDBC driver that does not need the type code and type name information may ignore it. To be portable, however, applications should always provide these values for user-defined and `REF` parameters. Although it is intended for user-defined and `REF` parameters, this method may be used to register a parameter of any JDBC type. If the parameter does not have a user-defined or `REF` type, the typeName parameter is ignored.

  Note: When reading the value of an out parameter, you must use the getter method whose Java type corresponds to the parameter's registered SQL type.

  ### HSQLDB-Specific Information:

  HSQLDB 1.7.2 does not support this feature.

  Calling this method always throws an `SQLException`.

  Specified by:
    `registerOutParameter` in interface `java.sql.CallableStatement`

  Registers the OUT parameter named `parameterName` to the JDBC type `sqlType`. All OUT parameters must be registered before a stored procedure is executed.

  The JDBC type specified by `sqlType` for an OUT parameter determines the Java type that must be used in the `get` method to read the value of that parameter.

  If the JDBC type expected to be returned to this output parameter is specific to this particular database, `sqlType` should be `java.sql.Types.OTHER`. The method `getObject(int)` retrieves the value.

  Registers the designated output parameter. This version of the method `registerOutParameter` should be used for a user-named or REF output parameter. Examples of user-named types include: STRUCT, DISTINCT, JAVA_OBJECT, and named array types.

  (JDBC4 clarification:) All OUT parameters must be registered before a stored procedure is executed.

  For a user-named parameter the fully-qualified SQL type name of the parameter should also be given, while a REF parameter requires that the fully-qualified type name of the referenced type be given. A JDBC driver that does not need the type code and type name information may ignore it. To be portable, however, applications should always provide these values for user-named and REF parameters. Although it is intended for user-named and REF parameters, this method may be used to register a parameter of any JDBC type. If the parameter does not have a user-named or REF type, the typeName parameter is ignored.

  Note: When reading the value of an out parameter, you must use the `getXXX` method whose Java type XXX corresponds to the parameter's registered SQL type.

  ### HSQLDB-Specific Information:

                   throws java.sql.SQLException

  Sets the value of the designated parameter with the given object. The second argument must be an object type; for integral values, the `java.lang` equivalent objects should be used.

  The given Java object will be converted to the given targetSqlType before being sent to the database. If the object has a custom mapping (is of a class implementing the interface `SQLData`), the JDBC driver should call the method `SQLData.writeSQL` to write it to the SQL data stream. If, on the other hand, the object is of a class implementing `Ref`, `Blob`, `Clob`, `Struct`, or `Array`, the driver should pass it to the database as a value of the corresponding SQL type.

  Note that this method may be used to pass datatabase- specific abstract data types.

  ### HSQLDB-Specific Information:

  Starting with 1.7.2, HSLQDB supports this.

  Specified by:
    `setObject` in interface `java.sql.CallableStatement`
  Parameters:
    `parameterName` - the name of the parameter
    `x` - the object containing the input parameter value
    `targetSqlType` - the SQL type (as defined in java.sql.Types) to be sent to the database. The scale argument may further qualify this type.
    `scale` - for java.sql.Types.DECIMAL or java.sql.Types.NUMERIC types, this is the number of digits after the decimal point. For all other types, this value will be ignored.
  Throws:
    `java.sql.SQLException` - if a database access error occurs

                          int targetSqlType)
                   throws java.sql.SQLException

  Sets the value of the designated parameter with the given object. This method is like the method `setObject` above, except that it assumes a scale of zero.

  ### HSQLDB-Specific Information:

  Starting with 1.7.2, HSLQDB supports this.

  Specified by:
    `setObject` in interface `java.sql.CallableStatement`
  Parameters:

### setObject

    public void setObject(java.lang.String parameterName,
                          java.lang.Object x)
                   throws java.sql.SQLException

  Sets the value of the designated parameter with the given object. The second parameter must be of type `Object`; therefore, the `java.lang` equivalent objects should be used for built-in types.

  The JDBC specification specifies a standard mapping from Java `Object` types to SQL types. The given argument will be converted to the corresponding SQL type before being sent to the database.

  Note that this method may be used to pass datatabase- specific abstract data types, by using a driver-specific Java type. If the object is of a class implementing the interface `SQLData`, the JDBC driver should call the method `SQLData.writeSQL` to write it to the SQL data stream. If, on the other hand, the object is of a class implementing `Ref`, `Blob`, `Clob`, `Struct`, or `Array`, the driver should pass it to the database as a value of the corresponding SQL type.

  This method throws an exception if there is an ambiguity, for example, if the object is of a class implementing more than one of the interfaces named above.

  ### HSQLDB-Specific Information:

  Starting with 1.7.2, HSLQDB supports this.

  Specified by:
    `setObject` in interface `java.sql.CallableStatement`
  Parameters:

                            throws java.sql.SQLException

  Sets the designated parameter to the given `Reader` object, which is the given number of characters long. When a very large UNICODE value is input to a `LONGVARCHAR` parameter, it may be more practical to send it via a `java.io.Reader` object. The data will be read from the stream as needed until end-of-file is reached. The JDBC driver will do any necessary conversion from UNICODE to the database char format.

  Note: This stream object can either be a standard Java stream object or your own subclass that implements the standard interface.

  ### HSQLDB-Specific Information:

  Starting with 1.7.2, HSLQDB supports this.

  Specified by:
    `setCharacterStream` in interface `java.sql.CallableStatement`

                 throws java.sql.SQLException

  Sets the designated parameter to the given `java.sql.Date` value, using the given `Calendar` object. The driver uses the `Calendar` object to construct an SQL `DATE` value, which the driver then sends to the database. With a a `Calendar` object, the driver can calculate the date taking into account a custom timezone. If no `Calendar` object is specified, the driver uses the default timezone, which is that of the virtual machine running the application.

If no `Calendar` object is specified, the driver uses the default timezone, which is that of the virtual machine running the application.

  ### HSQLDB-Specific Information:

  Starting with 1.7.2, HSLQDB supports this.

  Specified by:
    `setTime` in interface `java.sql.CallableStatement`
  Parameters:
    `parameterName` - the name of the parameter
    `x` - the parameter value
    `cal` - the `Calendar` object the driver will use to construct the time
  Throws:
    `java.sql.SQLException` - if a database access error occurs

                      throws java.sql.SQLException

  Sets the designated parameter to the given `java.sql.Timestamp` value, using the given `Calendar` object. The driver uses the `Calendar` object to construct an SQL `TIMESTAMP` value, which the driver then sends to the database. With a `Calendar` object, the driver can calculate the timestamp taking into account a custom timezone. If no `Calendar` object is specified, the driver uses the default timezone, which is that of the virtual machine running the application.

  ### HSQLDB-Specific Information:

                 throws java.sql.SQLException

  Sets the designated parameter to SQL `NULL`. This version of the method `setNull` should be used for user-defined types and `REF` type parameters. Examples of user-defined types include: `STRUCT`, `DISTINCT`, `JAVA_OBJECT`, and named array types.

  Note: To be portable, applications must give the SQL type code and the fully-qualified SQL type name when specifying a `NULL` user-defined or `REF` parameter. In the case of a user-defined type the name is the type name of the parameter itself. For a `REF` parameter, the name is the type name of the referenced type. If a JDBC driver does not need the type code or type name information, it may ignore it. Although it is intended for user-defined and `Ref` parameters, this method may be used to set a null parameter of any JDBC type. If the parameter does not have a user-defined or `REF` type, the given `typeName` is ignored.
