( resource stmt [, int mode] )
oci_execute() executes a previously parsed
statement (see oci_parse()). The optional
mode allows you to specify the
execution mode (default is OCI_COMMIT_ON_SUCCESS).
If you don't want statements to be committed automatically,
you should specify OCI_DEFAULT as your
When using OCI_DEFAULT mode, you're creating a
transaction. Transactions are automatically rolled back when you close
the connection, or when the script ends, whichever is soonest. You
need to explicitly call oci_commit() to commit
the transaction, or oci_rollback() to abort it.
Returns TRUE on success or FALSE on failure.
In PHP versions before 5.0.0 you must use ociexecute() instead.
This name still can be used, it was left as alias of
oci_execute() for downwards compatability.
This, however, is deprecated and not recommended.
