Anmerkungen
Hinweis: This function does not validate sql_text . The only way to find out if sql_text is a valid SQL or PL/SQL statement is to execute it.
Hinweis: In PHP versions before 5.0.0 use ociparse() instead. The old function name can still be used in current versions, however it is deprecated and not recommended.
