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 https://www.techonthenet.com/oracle/errors/ora00904.php #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 BY

When I try to create a table like this , I http://www.club-oracle.com/threads/ora-00904-invalid-identifier.693/ get the error below Code (Text): create table EMP ( ID NUMBER not null, CREATION_DATE TIMESTAMP(3) not null, COMMENT VARCHAR2(255), primary key (ID) ) Error: [B]ORA-00904:: invalid identifier[/B] SQL State: 42000 Error Code: 904 What am I missing? Thanks again (... and again) amy85, Apr 4, 2009 #1 tyro Forum Genius Messages: 368 Likes Received: 20 Trophy Points: 260 Location: India hey invalid identifier don't say sorry dear you can't use COMMENT as your column name (the invalid identifier) because it is a oracle reserved term. Use this Code (Text): create table EMP ( ID NUMBER not null, CREATION_DATE TIMESTAMP(3) not null, P_COMMENT VARCHAR2(255), primary key (ID) ) But if you must use COMMENT as a column name put it in between double quotes as below: Code 00904 invalid identifier (Text): create table EMP ( ID NUMBER not null, CREATION_DATE TIMESTAMP(3) not null, "COMMENT" VARCHAR2(255), primary key (ID) ) Cheers [] tyro, Apr 4, 2009 #2 amy85 likes this. rajavu Forum Guru Messages: 815 Likes Received: 52 Trophy Points: 610 Location: @ Bangalore , India As you might be knowing , it is not desirable to use the reserved words as a column name of a table . You have to use double quotes always in the application to refer the reserved key word column name. It is recommended to change the column name as suggested by Tyro. Code (SQL): SQL> CREATE TABLE EMP12 ( 2 ID NUMBER NOT NULL, 3 CREATION_DATE TIMESTAMP(3) NOT NULL, 4 "COMMENT" VARCHAR2(255), 5 PRIMARY KEY (ID) 6 ) 7 ; TABLE created. SQL> INSERT INTO EMP12 VALUES ( 10, SYSTIMESTAMP, '1D=10'); 1 ROW created. SQL> SELECT ID ,COMMENT FROM EMP12 ; SELECT ID ,COMMENT FROM EMP12 * ERROR at line 1: ORA-00936: missing expression SQL> SELECT ID ,"COMMENT" FROM EMP12; ID COMMENT ---------- -------------------- 10 1D=10 SQL> rajavu, Apr 8, 2009 #3 amy85 likes this. amy85 Active Member
