JDBCExecuteStatementDataSink

The JDBCExecuteStatementDataSink is used to execute an arbitrary SQL statement. The statement is compiled when the data sink is opened. Parameters can be used to fine tune the runtime behavior. The parameter values are deferred expression which are evaluated when an object is exported. This module is tested with the JDBC drivers for Oracle, PostgreSQL and MariaDB databases, so it officially only supports MariaDB and Oracle databases.
