[AccessD] Data Type Mismatch in criteria expression

[McGillivray, Don]

Right you are!

I've been so in the habit of doing it that way (based on the examples from MS) that I never tried it otherwise.  Figured it was required generally.

Hate to think of all the keystrokes I've wasted doing that . . .  :-P

Hi Don

Just a minor point in the context of the discussion, but... I think the brackets would only be necessary if there was a space in the name.

Regards
Steve

Oops.  Meant to point out also that the column name "agentid" needs the square brackets around it.

Try:

DCount("[agentid]", "agent", "[agentid] = '" & strAgentID & "'")

The criterion, being a string, must be surrounded by ' .

If you have a moment, can you look at this snippet ?


Don't judge me, I inherited the table and field names. And I figured it was too much to change all the rookie naming conventions....

I just can't see the problem.

"agentid" is a field name in the table "agent". It is a primary key and a STRING data type.
intAgentCount is a integer type vba variable.
strAgentID is a string type vba variable.

    intAgentCount = DCount("agentid", "agent", "[agentid] = " & strAgentID)

My objective is to determine if a record is already in the table for a given agentid, and if not, to insert one.

TIA
