Null - Not Null - Or?


I have a table with 2 fields, field1 and field 2.  Field 1 has 100 records, field 2 only has 75 records.  When field 2 is null, I want to assign a value to it but the 25 records without data show up with what appears to be a null value.   I have tried several things.  1st, when I do a len(field2) all of them show up as 10, even if they do not have data in them.  I have tried doing a trim on field 2 but it deletes the entire line leaving me with 75 records not 100.

How do I deal with a field that has no data in it, but has a length of 10?  I want the script to be, if Field2 is Null, assign Field1 as its value, else Field2.

Thanks,

Len(trim(Field2)) = 0 always does the trick – unless you have hard spaces in the string. These are not trimmed. In such a case you need to do Len(trim(purgechar(Field2, chr(160))))=0 instead.

I will try this as it looks like there are 10 hard spaces there.

Thanks all for your replies, very helpful!
