Insufficient key column information for updating or refreshing 3.Insufficient key column information for updating or refreshing 4.Hi VB'ers I just discovered something I thought I would pass along. Of course I'm probably the last one in the world to realize this but here goes. The text to the msg is: Insufficient key column information for updating or refreshing What the heck is going on? I hope you were able to follow that Thank much Trudye I'm really clueless on what is happing to you. DON'T use default properties My second suggestion DON'T use the BANG notation Do Until ado Rec. DON'T use default properties Hey Semper Fi Down Unda, I know this is a little off subject, but what do you feel about using the shorter Collect property instead of the longer, slower Fields(0). A test I did with 10 million rows run on multiple systems has shown that using the Bang notation is just as slow as rs. I have a problem in most cases with default properties because it can be more confusing when you jump into an exsisting project trying to figure out if they are wanting to use a default property when doing a set or the actual object itself. I checked both tables and neither one had duplicate entries. Which works find if I remove the "Needs"/"Elig" load. Add Item method of the combo box takes up to 2 parameters.1st being a string to display in the combo box2nd being optional is the index where to insert this in the list As far as ADO goes you have a recordset....are pointing to a current record. Are you leaving out some databound issues some where? I have to admit I break down on that and use the default. Microsoft do teach in the MOC that the BANG is faster but it is a lye. Collect("Last Name") can only refer to 1 thingwhere using rs. Son Of Emidec1100’s observation was right-on, that is what I read in MS Knowledgebase.

Hi : Does anyone know why the following error "Insufficient key column information for updating or refreshing" happens when I try to update a join query? ADOQuery CCBefore Edit(Data Set: TData Set); begin Save Enabled := True; end; procedure TFNew Car. Screen Shot is because the data has not been posted. You're trying to insert and update tuples from two tables, but you fetched only a foreign key of a detail table. Enabled := Value; Save Clicked := False; end; procedure TFNew Car. FNew Car form allows users to enter new record (cars) successfully but when try to update a field following error appear as well " Insufficient key column information for updating or refreshing" What i am doing wrong??? I find it more efficient, and you are not dealing with default properties or the a bang either. I'm one to drop use of syntax that is there for "Backward compatibility"Just my opinion. Also if duplication existed in any of the tables when I load them individually the error would still occur wouldn't it? I have just been away from this thread because I lost my hdd and thus had to start my VB project over form scratch. I also had one day’s work to make up but that was not so bad. When I get better at this I know that the light bulb will come on and I will see the wisdom of your words. Connection String = "Provider=SQEDB.1; Integrated Security=SSPI; Persist Security Info=False; Initial Catalog=Northwind; Data Source=My SQLServer" conn. Value property when returning just the field values (when accessing more properties, a using field object variable is also more efficient)? Also if you start using full notation you can start using shortcuts like Dim fld as ADODB. Fields("Last Name")and use fld to access it in a loop which is MUCH faster. Two thoughts came to my little mind, maybe the loading of two combo boxes was causing the appearance of duplication.
