VBA: executing an Update query is failing without an errro

    In Access VBA, I build an update query, and execute it as follows:

    Dim strSQL as String
    Dim db as Database
    Set db = CurrentDb
    strSQL = "UPDATE [...snip...]"
    db.Execute strSQL

    The update does not take place, but there is no error reported. The
    code has worked previously, but I have had to rebuild the backend
    database (another MDB) following a data corruption. I don't know if
    this is relevant.

    The UPDATE string is valid: I created a new query, and pasted the code
    into the SQL view. It ran without a problem and updated the record

    Any ideas?

    Do two things:

    Place a debug.print in your code as follows:

    debug.Print strSQL
    db.Execute strSQL

    Now, run the code. Now, go to the debug window (ctrl-g), and now cut and
    paste the sql into the query builder.

    Can you run it in the query builder?....can you see any problems with it?

    By the way, if you want have it error out, then use

    db.Execute strSQL, dbFailOnError
