Description When you encounter an ORA-00904 error, the following error message will appear: ORA-00904: invalid identifier Cause You tried to execute a SQL statement that included an invalid column name or the column name is missing. This commonly occurs when you reference an invalid alias https://www.techonthenet.com/oracle/errors/ora00904.php in a SELECT statement. Resolution The option(s) to resolve this Oracle error are: Option #1 Rewrite your SQL to include a valid column name. To be a valid column name the following criteria must be met: The column name must begin with a letter. The column name can not be longer than 30 characters. The column name must be made up of alphanumeric characters or the 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. Let's look at an example of how to resolve an ORA-00904 error. For example, if you ran the following SELECT statement, you would receive an ORA-00904 error: SQL> SELECT contact_id AS "c_id", last_name, first_name 2 FROM contacts 3 ORDER BY "cid"; ORDER BY "cid" * ERROR at line 3: ORA-00904: "cid": invalid identifier This error was created by aliasing a column, but then mistyping the alias later. In this example, we created the alias called "c_id" for the contact_id, but then called it as "cid" in the ORDER BY clause. To resolve this error, we can modi

The SQL statement includes a column name which does not currently exist. This error is most common when querying a SELECT statement. To resolve this error, first check to make sure the column name being referenced exists. If it does not exist, you must create one before attempting to execute an SQL statement with the column. If the column name exists, be sure to check 00904 invalid identifier that the column name is in the proper syntax. To be valid, the column name must meet the following criteria: The column name cannot be a reserved word. The first letter of the column name must be a letter. The column name must be less than or equal to 30 characters. The column name must be made up of alphanumeric characters. The column name can contain any of the following 3 characters: $, _, #. If the column name includes any other characters, it must be enclosed with double quotation marks. The following is an example of an SQL statement containing Error Ora-00904: SELECT column_name AS "column_id" FROM table ORDER BY column_id; In this example, the name “column_id” is aliasing the column_name, which is later queried as column_id. Notice the missing double quotation marks in the second column_id. To resolve the error, follow the proper syntax by enclosing “column_id” in double quotation marks: SELECT column_name AS “column_id” FROM table ORDER BY “column_id”; To avoid seeing error Ora-00904 in the future, make sure the column name meets the criteria for a valid column name. Rewrite the query to follow this format. If you are attempting to query a column name which does

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 cha
