ORA-01406: fetched column value was

truncated tips

Oracle Error Tips by Burleson Consulting (S. Karam)

 

The Oracle docs note this on the ora-01406 error:

ORA-01406 fetched column value was truncated
 
Cause: In a host language program, a FETCH operation was forced to truncate a character string. The program buffer area for this column was not large enough to contain the entire string. The cursor return code from the fetch was +3.
 
Action: Increase the column buffer area to hold the largest column value or perform other appropriate processing.

ORA-01406 is thrown when a FETCH was forced to truncate a column name or character string in host language programs.  ORA-01406 is caused by the column's program buffer area which isn't large enough to hold the string in it's entirety, while the cursor return code is +3.

To resolve ORA-01406, you should try to:

  •  expand the column buffer area so that it can hold the largest column value
  • check your insert syntax, allowing for appropriate processing

You should note that ORA-01406 is described in MOSC as a bug (4546618), which has supposedly been fixed in 10.2.0.3
