DB2 10.5 for Linux, UNIX, and Windows

DB2PreparedStatement interface

The com.ibm.db2.jcc.DB2PreparedStatement interface extends the com.ibm.db2.jcc.DB2Statement and java.sql.PreparedStatement interfaces.

DB2PreparedStatement fields

The following constants are defined only for the IBM® Data Server Driver for JDBC and SQLJ.

public static DBIndicatorDefault DB_PARAMETER_DEFAULT: This constant can be used with standard interfaces, such as PreparedStatement.setObject or ResultSet.updateObject to indicate that the default value is assigned to the associated parameter.
public static DBIndicatorUnassigned DB_PARAMETER_UNASSIGNED: This constant can be used with standard interfaces, such as PreparedStatement.setObject or ResultSet.updateObject to indicate that the associated parameter is unassigned.

DB2PreparedStatement methods

The following methods are defined only for the IBM Data Server Driver for JDBC and SQLJ.

executeDB2QueryBatch

Format:

public void executeDB2QueryBatch()
  throws java.sql.SQLException

Executes a statement batch that contains queries with parameters.

This method is not supported for connections to IBM Informix® data sources.

getDBGeneratedKeys

Format:

public java.sql.ResultSet[] getDBGeneratedKeys()
  throws java.sql.SQLException

Retrieves automatically generated keys that were created when INSERT statements were executed in a batch. Each ResultSet object that is returned contains the automatically generated keys for a single statement in the batch.

getDBGeneratedKeys returns an array of length 0 under the following conditions:

getDBGeneratedKeys is called out of sequence. For example, if getDBGeneratedKeys is called before executeBatch, an array of length 0 is returned.

The PreparedStatement that is executed in a batch was not created using one of the following methods:

Connection.prepareStatement(String sql, int[] autoGeneratedKeys)
Connection.prepareStatement(String sql, String[] autoGeneratedColumnNames)
Connection.prepareStatement(String sql, Statement.RETURN_GENERATED_KEYS)

If getDBGeneratedKeys is called against a PreparedStatement that was created using one of the previously listed methods, and the PreparedStatement is not in a batch, a single ResultSet is returned.

getEstimateCost

Format:

public int getEstimateCost()
  throws java.sql.SQLException

Returns the estimated cost of an SQL statement from the data server after the data server dynamically prepares the statement successfully. This value is the same as the fourth element in the sqlerrd array of the SQLCA.

If the deferPrepares property is set to true, calling getEstimateCost causes the data server to execute a dynamic prepare operation.

If the SQL statement cannot be prepared, or the data server does not return estimated cost information at prepare time, getEstimateCost returns -1.

getEstimateRowCount

Format:

public int getEstimateRowCount()
  throws java.sql.SQLException

Returns the estimated row count for an SQL statement from the data server after the data server dynamically prepares the statement successfully. This value is the same as the third element in the sqlerrd array of the SQLCA.

If the deferPrepares property is set to true, calling getEstimateRowCount causes the data server to execute a dynamic prepare operation.

If the SQL statement cannot be prepared, or the data server does not return estimated row count information at prepare time, getEstimateRowCount returns -1.

setDBTimestamp

Format:

public void setDBTimestamp(int parameterIndex, 
  DBTimestamp timestamp)
  throws java.sql.SQLException

Parameters:

parameterIndex: The index of the parameter marker to which a DBTimestamp variable value is assigned.
