Constructor Detail

ResultSetReturnImpl

public ResultSetReturnImpl(JdbcCoordinator jdbcCoordinator)

Constructs a ResultSetReturnImpl

Parameters:

jdbcCoordinator - The JdbcCoordinator

Method Detail

extract

public ResultSet extract(PreparedStatement statement)

Description copied from interface: ResultSetReturn

Extract the ResultSet from the PreparedStatement.

If user passes CallableStatement reference, this method calls ResultSetReturn.extract(CallableStatement) internally. Otherwise, generally speaking, PreparedStatement.executeQuery() is called

Specified by:

extract in interface ResultSetReturn

Parameters:

statement - The PreparedStatement from which to extract the ResultSet

Returns:

The extracted ResultSet

extract

public ResultSet extract(CallableStatement callableStatement)

Description copied from interface: ResultSetReturn

Extract the ResultSet from the CallableStatement. Note that this is the limited legacy form which delegates to Dialect.getResultSet(java.sql.CallableStatement). Better option is to integrate ProcedureCall-like hooks

Specified by:

extract in interface ResultSetReturn

Parameters:

callableStatement - The CallableStatement from which to extract the ResultSet

Returns:

The extracted ResultSet

extract

public ResultSet extract(Statement statement,
                         String sql)

Description copied from interface: ResultSetReturn

Performs the given SQL statement, expecting a ResultSet in return

Specified by:

extract in interface ResultSetReturn

Parameters:

statement - The JDBC Statement object to use

sql - The SQL to execute

Returns:

The resulting ResultSet

execute

public ResultSet execute(PreparedStatement statement)

Description copied from interface: ResultSetReturn

Execute the PreparedStatement return its first ResultSet, if any. If there is no ResultSet, returns null

Specified by:

execute in interface ResultSetReturn

Parameters:

statement - The PreparedStatement to execute

Returns:

The extracted ResultSet, or null

execute

public ResultSet execute(Statement statement,
                         String sql)

Description copied from interface: ResultSetReturn

Performs the given SQL statement, returning its first ResultSet, if any. If there is no ResultSet, returns null

Specified by:

execute in interface ResultSetReturn

Parameters:

statement - The JDBC Statement object to use

sql - The SQL to execute

Returns:

The extracted ResultSet, or null

executeUpdate

public int executeUpdate(PreparedStatement statement)

Description copied from interface: ResultSetReturn

Execute the PreparedStatement, returning its "affected row count".

Specified by:

executeUpdate in interface ResultSetReturn

Parameters:

statement - The PreparedStatement to execute

Returns:

The PreparedStatement.executeUpdate() result

executeUpdate

public int executeUpdate(Statement statement,
                         String sql)

Description copied from interface: ResultSetReturn

Execute the given SQL statement returning its "affected row count".

Specified by:

executeUpdate in interface ResultSetReturn

Parameters:

statement - The JDBC Statement object to use

sql - The SQL to execute

Returns:

The Statement.executeUpdate(String) result
