Hi Experts,

Delete, Update and Insert into SQL can be used in
objConnection.Execute
They can also be used in
objRecordset.Open?
If thay are, is there any difference?

Thank you in advance.

Hello

Normally we use objConnection.Execute for executing update/insert statements.. where we don't need the out put in a recordset.. or we don't need to manuplate recordset default properties.. but when using select statement with objConnection.Execute.. it will restrict recordset generated by this method to only to the default properties of the recordset.. it means.. u wont able to chnage the cursor type/location of the recordset.. which wont allow you to use recordCount, absolutePosition, paging etc very usefull and powerfull properties of the recordset..

Ofcourse using objConnection.Execute for select statement is very quick to code and also takes mariginal less resources.. only when you are not required any recordset defailt property..

make sense ??

Thank you very much!

In my case, I need to do
  strSQL = "Delete * From Table1"
  objConnection.Execute strSQL
  strSQL = "Insert Into Table1([IP]) Values('" & userIP & "')"
  objConnection.Execute strSQL
do you think I can lock like this:
  objRecordset.Open "Delete * From Table1", objConnection, 2, 2
  objRecordset.AddNew
  objRecordset.Fields("IP") = userIP

that will work Daveask, just make sure when you are using objRecordset.Fields("IP") = userIP and then objRecordset.Update that you open your Recordset with the paramaters of 1,3.

ie : objRecordset.Open SQL, Conn, 1, 3

1, 3 will set the mode to allow you to update fields with a recordset.

Cheers,

Daveask, why do you need to lock the recordset?  Nobody is going to be able to access it since you close it right after you are done.  Other combinations than 1,3 are useable, however, to keep your position and for the best results I've found I use 1,3.  always works for me.

Cheers,  g/l in the rest of your coding!
