Question

i am connecting to a mysql database through excel using odbc

what does this line do?

Set rs = oConn.Execute("SELECT @@identity", , adCmdText)

i am having trouble updating the database:

   With rs
        .AddNew ' create a new record
        ' add values to each field in the record
        .Fields("datapath") = dpath
        .Fields("analysistime") = atime
        .Fields("reporttime") = rtime
        .Fields("lastcalib") = lcalib
        .Fields("analystname") = aname
        .Fields("reportname") = rname
        .Fields("batchstate") = "bstate"
        .Fields("instrument") = "NA"
        .Update ' stores the new record
    End With

it is ONLY updating .Fields(“instrument”) = “NA”, but for all other fields it is putting NULL values

Answer 1

It selects (and returns) the last value inserted into an IDENTITY COLUMN in the current connection.
