Error Message Learn the cause and how to resolve the ORA-00904 error message in Oracle. 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 ora-00904 invalid identifier in oracle forms 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 modify our SELECT statement to use the correct alias name in the ORDER BY clause as follows: SQL> SELECT con

ora 00904 invalid identifier insert statement EXP-00008: ORACLE error 904 encountered tips Oracle Database Tips by Burleson Consulting Question: I am trying to export a table and I have this "EXP-00008: https://www.techonthenet.com/oracle/errors/ora00904.php ORACLE error 904 encountered" error message: Connected to: Oracle8i Enterprise Edition Release 8.1.7.4.0 - Production About to export specified tables via Conventional Path ... EXP-00008: ORACLE error 904 encountered ORA-00904: invalid column name Answer: The EXP-0008 with the 904 "invalid column name" will always write a trace file, and you http://www.dba-oracle.com/t_exp_00008_904_error.htm can check the trace file in your UDUMP directory to see the specific cause. The "EXP-00008: ORACLE error 904 encountered" error can happen for several reasons: The most common cause of the EXP-0008 with the 904 code is a mismatch between the Oracle client and the database. Verify that the version of your exp utility matches the database version. This 904 error can happen if you forget to run catproc.sql. Also see MOSC Note:1017276.102 "Oracle8i Export Fails on Synonym Export with EXP-00008 and ORA-00904". This notes that a synonym named "DBMS_JAVA" or "DBMS_JAVA_TEST" may exist without a corresponding package.

Most of the application works very well. We do have somereports that are throwing the ORA-00904 invalid identifier error and Ihaven't been able to find anything on MetaLink that is of any value yet. Idid just find out that the reports are running invalid identifier on a Windows server pullingthe data into SQL Server and doing the processing there before returning theresults back to the application.Does anyone have any suggestions where I can look for this? The developerwho manages the Windows/SQL Server side of things insists it's the 10gdatabase and not his side of the house and I have no way invalid identifier in to prove/disprovehis assertion.Thanks for any help/suggestions.Sandy--http://www.freelists.org/webpage/oracle-l reply Tweet Search Discussions Search All Groups oracle-l 6 responses Oldest Nested Tim Gorman Sandra, Activate a SQL trace (any level) against a database session prior to running this report, and then examine the "raw" trace file for the presence of a line that looks like: PARSE ERROR #n: .... err=904 Search in particular for the phrase "err=" (i.e. "err=904") and, in the case of a parsing error like ORA-00904, the SQL statement text should appear right after it.

see this message: The following statement encountered a error during parse: SELECT 1 FROM DUAL WHERE some_predicate_here Error encountered: ORA-00904 A some_predicate_here is the predicate from ON clause of a MERGE statement executed by the session. Up until recently I didn't know why that happens, and since the error is not reported to the end-user there's no big problem other than very little annoyance. This is an example: drop table t1 cascade constraints purge; create table t1 (x, y, pad) as select rownum, mod(rownum, 100), lpad('x', 10, 'x') from dual connect by level <= 1000; exec dbms_stats.gather_table_stats(user, 't1') exec dbms_session.session_trace_enable(false) alter session set events '10053 trace name context forever, level 2'; merge into t1 using (select 1 x, lpad('y', 10, 'y') pad from dual) t2 on (t1.x = t2.x) when matched then update set t1.pad = t2.pad when not matched then insert (x,y,pad) values (t2.x, t2.x, t2.pad); alter session set events '10053 trace name context off'; exec dbms_session.session_trace_disable And trace file excerpt: PARSE ERROR #5:len=36 dep=1 uid=60 oct=3 lid=60 tim=1266258229533447 err=904 SELECT 1 FROM DUAL WHERE t1.x = t2.x CLOSE #5:c=0,e=4,dep=1,type=0,tim=1266258229533578 Registered qb: MRG$1 0x84379c (PARSER) --------------------- QUERY BLOCK SIGNATURE --------------------- ... ====================== END SQL Statement Dump ====================== ===================== PARSING IN CURSOR #2 len=198 dep=0 uid=60 oct=189 lid=60 tim=1266258229984031 hv=3137650586 ad='3afa49c8' sqlid='aq4m8daxh9gwu' merge into t1 using (select 1 x, lpad('y', 10, 'y') pad from dual) t2 on (t1.x = t2.x) when matched then update set t1.pad = t2.pad when not matched then insert (x,y,pad) values (t2.x, t2.x, t2.pad) END OF STMT PARSE #2:c=45993,e=451460,p=0,cr=7,cu=0,mis=1,r=0,dep=0,og=1,plh=1461866594,tim=1266258229984030 EXEC #2:c=0,e=16490,p=0,cr=6,cu=3,mis=0,r=1,dep=0,og=1,plh=1461866594,tim=1266258230000570 STAT #2 id=1 cnt=0
