Commands and SQL Statements


The Loader can execute commands and SQL statements.


Creating a Database Session

You can execute the commands and SQL statements for importing and exporting data only after you have successfully started a database session. This ensures that only suitably authorized owners can import and export.

SQL Statements

The Loader can execute the SQL statements required for exporting and importing. DDL statements, in particular, are vital for importing data (SQL Reference Manual: SQL Statements: Overview).

Database queries, however, return only status messages.

COMMIT and ROLLBACK statements are only active in the mode AUTOCOMMIT OFF (AUTOCOMMIT Command).
