Burleson Consulting Question: I am running a SQL statement and I get a SQL*Plus error ORA-00904 invalid identifier. ora-00904 invalid identifier in oracle forms Answer: When ORA-00904 occurs, you must enter a valid column name as it is either missing or the one entered is invalid. The "invalid identifier" most common happens when you are referencing an invalid alias in http://docs.oracle.com/cd/B10501_01/server.920/a96525/e900.htm a select statement. The Oracle docs note this on the ORA-00904 error: ORA-00904 string: invalid identifier Cause: The column name entered is either missing or invalid. Action: Enter a valid column name. A valid column name must begin with a letter, be less than or equal to 30 characters, and consist of only alphanumeric characters and the special characters $, _, and #. If it contains other characters, then http://www.dba-oracle.com/t_ora_00904_string_invalid_identifier.htm it must be enclosed in double quotation marks. It may not be a reserved word. To avoid ORA-00904, column names cannot be a reserved word, and must contain these four criteria to be valid: begin with a letter be less than or equal to thirty characters consist only of alphanumeric and the special characters ($_#); other characters need double quotation marks around them Another important factor in correcting ORA-00904 is remembering to run catproc.sql You can also check your trace file to find the particular error which is causing the ORA-00904 to occur.

If it contains other characters, then it must be enclosed in double quotation marks. It may not be a reserved word. 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
