ORA-00984: Column Not Allowed Here tips

Oracle Error Tips by Donald Burleson


The Oracle docs note this on the ora-00984 error*:


ORA-00984 column not allowed here
Cause: A column name was used in an expression where it is not permitted, such as in the VALUES clause of an INSERT statement.
Action: Check the syntax of the statement and use column names only where appropriate.

An ORA-00984 will be thrown if a column name (like in the VALUES clause of an INSERT statement), is used in an expression where it is not permitted.  You may have used a column name in an expression where it is not permitted.  Typically, ORA-00984 occurs while including a column name in the VALUES clause of an INSERT statement.

To correct ORA-00984, you simply need to view the syntax of the SQL statement and only use column names where they are appropriate. 

  • You may also find it appropriate to include a character value, in the INSERT statement, instead of the column name.

This was a helpful question relating to ORA-00984 from "ORACLE DBA FORUM":


I have received an ORA-00984 error, but am not seeing anything in the AUD$ table.  I have also not found anything in the other views, or alert.log file.  How can I find the fault causing the ORA-00984?


You should look for the DML error logging (log the failed insert)

To resolve ORA-00984, there are a few different ways that you can audit within Oracle, in addition to the AUDIT syntax:

  1. Use system-level triggers (DML and DDL) to audit
  2. Use LogMiner (DML and DDL)

These links may also be helpful in resolving ORA_00984:
