Reference: http://docs.oracle.com/cd/B10500_01/server.920/a96525/e900.htm ORA-00904 is a very simple issue. ORA-00904 may occur when we try to create or alter a table with invalid column name. It also may occur when we try to reference a non existing column in a select / insert / update / delete statement. Examples which may lead to ORA-00904 are following: SQL> CREATE TABLE TEST 2 ( 3 ID NUMBER, 4 NAME VARCHAR2(200), 5 COMMENT VARCHAR2(4000) 6 ); COMMENT VARCHAR2(4000) * ERROR at line 5: ORA-00904: invalid identifier ========================================================== SQL> select empid from scott.emp; select empid from scott.emp * ERROR at line 1: ORA-00904: "EMPID": invalid identifier ========================================================== SQL> update scott.emp set salary=1000 where empno = 3625; update scott.emp set salary=1000 where empno = 3625 * ERROR at line 1: ORA-00904: "SALARY": invalid identifier ========================================================== SQL> delete scott.emp where empid = 3625; delete scott.emp where empid = 3625 * ERROR at line 1: ORA-00904: "EMPID": invalid identifier ========================================================== SQL> insert into scott.emp (empno, empname, sal) 2 values(3625, 'Amit', 10000); insert into scott.emp (empno, empname, sal) * ERROR at line 1: ORA-00904: "EMPNAME": invalid identifier ========================================================== SQL> select emp.ename from scott.emp e; select emp.ename from scott.emp e * ERROR at line 1: ORA-00904: "EMP"."ENAME": invalid identifier ORA-00904 can simply be avoided by using the valid column name in create or alter statement. Also for DML statements ORA-00904 can be avoided by making a valid reference to the column name or the alias. A valid column name must follow following criteria - The column name must begin with a letter. - The column name can not be of more than 30 characters. - The column name must be made up of alphanumeric characters - The column name may contain following special characters: $, _, and #. - If the column name uses any other characters, it must be enclosed in double quotation marks. - The column name can not be a reserved word.
