>>>The purpose of the above is to create a string of entity codes (nbsp) equal to the number of spaces after some entry in a field. The field name is REFERENCE. It used to be up to 10 characters in length. And the user was able to enter only up to 10 characters. And the above code worked.
>>>Then I increased the length of the field to 15. But the entry in the field is still the same, less or equal to 10 characters.

>>>If I change the 10 in the above REPLICATE with 15, no error.

It should be wider since the SQL Select concatinats the fields REFERENCE and REPLICATE(ENTITY) AND REF_DESCR field. So, basically only one or two letters from REF_DESCR go into the column WO_REFER1.

The CAST() expression you suggested gives Syntax Error. I don't understand why; although maybe Casting from Character to Character is not allowed (I am just guessing)
If there was a NULL value of a possible table corruption, the change from 10 to 15 should not make a difference. But it does. The number in the first REPLICATE expression should be equal or greater than the field length. At least, this is the result that I see so far.
Thank you.
