ORA-01401 inserted value too large for column tips

Oracle Error Tips by Burleson


The Oracle docs note this about ORA-01401:


       ORA-01401 inserted value too large for column
Cause: The value entered is larger than the maximum width defined for the column.
Action: Enter a value smaller than the column width or use the MODIFY option with ALTER TABLE to expand the column width.


Here, a user encounters ORA-01401 with 9i.


Question: I have a table with 118 columns and keep receiving ORA-01401 when I attempt to put the data in a table with a cursor.  Is there any way I can figure out which column is throwing the ORA-01401 error?

Answer: You should note that in 10g, the error has been updated and includes further information, making it easier to resolve ORA-01401.  SeeORA-12899_value_too_large_for_column.


Otherwise, you call always test your data using PL/SQL.  Or, you can always try making an exception with PRAGMA EXCEPTION_INIT :

my_exception EXCEPTION;
PRAGMA EXCEPTION_INIT (my_exception, -1401);
insert into table () values ..............
WHEN my_exception THEN dbms_output.put_line('Column value too long');
