Cannot update Oracle database with execute: methods
Unlike the execute: methods of GsSybaseConnection, which allow
execution of insert, update, and delete statements, as well as select
statements, the execute: methods of GsOracleConnection do not allow
the execution of insert, update, or delete statements.
Workaround
Use the executeNoResults: method to execute update, delete, and insert
SQL statements on Oracle.
