Hello,

Instead of the 'IS NOT NULL' I want to use "".

sSqlSelect = "Select tbl_DiscrepancyRecords.DDepartment From tbl_DiscrepancyRecords Where(tbl_DiscrepancyRecords.DDepartment IS NOT NULL);"

Thanks...

Beware, in a database an 'Empty String' is different than a 'Null'

sSqlSelect = "Select tbl_DiscrepancyRecords.DDepartment From tbl_DiscrepancyRecords Where(tbl_DiscrepancyRecords.DDepartment > '')"

One thing to remember if you use

... <> ''

This will return Nulls as they are less than an empty string

Hi ADawn,
It appears that you have forgotten this question. I will ask Community Support to close it unless you finalize it within 7 days. I will suggest to:

    Accept deighton's comment(s) as an answer.

ADawn, if you think your question was not answered at all or if you need help, you can simply post a new comment here.  Community Support moderators will follow up.

EXPERTS: If you disagree with that recommendation, please post an explanatory comment.
