>Thanks. What I fear is that if the first record found has a null value in a column and it is replaced with NVL(null,0), an one digit wide column is created. If later a larger integer if found it will not fit in the column. At least I used to find that problem inf FPDos (not with nulls, of course). Maybe it has long been fixed.

For all sorts of expressions, I sometimes use:
select 00000 + VariableLengthNumber() ...
Note that I don't care if the column happens to have more than "x" digits wide; I just want to make sure it doesn't have less.
