ORA-00904: STRING: invalid identifier tips Oracle ora 00904 %s invalid identifier Error Tips by Burleson Consulting Question: I am running a SQL statement and I get a SQL*Plus error ORA-00904 invalid identifier. Answer: When ORA-00904 http://stackoverflow.com/questions/6027961/ora-00904-invalid-identifier 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 a select statement. The Oracle docs note this on the ORA-00904 error: ORA-00904 string: invalid identifier Cause: The column name entered http://www.dba-oracle.com/t_ora_00904_string_invalid_identifier.htm 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 $, _, and #. If it contains other characters, then it must be enclosed in double quotation marks. It may not be a reserved word. To avoid ORA-00904, column names cannot be a reserved word, and must contain these four criteria to be valid: begin with a letter be less than or equal to thirty characters consist only of alphanumeric and the special characters ($_#); 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.

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 in a SELECT statement. Resolution The option(s) to resolve this Oracle error are: Option 00904 invalid identifier #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 modify our SELECT statement to use the correct alias name in the ORDER BY clause as follows: SQL> SELECT contact_id AS "c_id", last_name, first_name 2 FROM contacts 3 ORDER
less than or equal to 30 characters, and consist of only alphanumeric characters and the special characters $, _, and #. 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 double quotation marks. - The column name
