Question : Trouble Converting SQL Server Query to MS Access

I'm having issues converting a SQL Server query to MS Access to use in my VB.NET program.

My original SQL Server query:

My MS Access version keeps telling me that I'm missing an operator, but I can't figure out what I'm missing.

Answer : Trouble Converting SQL Server Query to MS Access

Your SQL habits could use some improvement.  ;-)

You probably need to stop trying to use the column number in your ORDER BY clause and, instead of using the 4 use CD_WELLBORE_FORMATION.update_date (or whichever column name you are wanting to actually order by).

Also, look at the following:

dbo_CD_DATUM.well_id + dbo_CD_DATUM.datum_id

If those are character strings, then you need to use an ampersand (&) to concatenate them plus you probably want to wrap that in parenthesis:

OR (dbo_CD_DATUM.well_id + dbo_CD_DATUM.datum_id) IN ('03q2DecAl4nlEgX',
                                                          '86zNT2KSuII6yfH', ... , 'ZILDpIPYMHfWqVj')

You might want to put an alias on the following line:

dbo_CD_WELLBORE_FORMATION.prognosed_md + NZ(dbo_CD_DATUM.datum_elevation, 0),
