I spent a bit more time on this issue, and it appears that the records in question fail because a date column is set to a default value of 0000-00-00. For some reason when a record is fetched with a date field set like this then both BOF, and EOF are set TRUE. When I changed the value of the cert_issue_date as follows, then the record could be successfully fetched: UPDATE eric.test_table SET cert_issue_date = '2000-12-11' WHERE name = 'EAA AVIATION FOUNDATION INC' AND tail_num = 'N1AC'; This appears to be the same issue that was raised back in defect #1680, but it was closed as not reproducible at that time.

Based on ODBC spec, I have fixed ODBC v5 to return an error 22007: Error #1(22007)error=0: [MySQL][MyODBC 5.00.12] Invalid datetime format This fix is committed in rev#785.

Should 3.51 also be changed?

It also happens when subqueries return a null value. It happens on recordcount and also if you try MoveNext when the next record has the NULL value. It happens on the two versions (3.51.19 and 5). Please check it. This bug is making it very complex to migrate from Access to MySQL.

Eric, in fact, this is a duplicate of Bug#9410 (problem fixed with patch for Bug#13766) and the rest of it is noted in Bug#30539. Agree? Did you try with .18 or .19 with options described in Bug#13766?

Claudio, working on Bug#28016 I tested NULL and IFNULL behavior in regards of updating records like this: Do While Not rs.EOF if IsNULL(rs(4)) Then rs.Fields("Marker") = "Z1" rs.update end if rs.MoveNext Loop on a table with ~300000 records and found no problems. Can you be more specific and provide me with self contained test case, if possible, exhibiting the problem bothering you so I can check.
