ORA-00900: invalid SQL statement

I got ” ORA-00900: invalid SQL statement ”  error in Oracle database.

 

ORA-00900: invalid SQL statement

 

Details of error are as follows.

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

Action: Correct the syntax or install the Procedural Option.
