ORA-00900
invalid SQL statement
Cause
The statement was not recognized as a valid SQL statement. This error can occurred if the Procedural Option was not installed and a SQL statement was issued that requires this option (for example, a CREATE PROCEDURE statement). You can determine if the Procedural Option was installed by starting SQL*Plus. If the PL/SQL banner was not displayed, then the option was not installed.
Action
Correct the syntax or install the Procedural Option.
