Does anyone use odac to connect to the database? Question? Delphi/Windows SDK/API
I used odac to connect to the database. In the formcreate time, when I open the SQL statement, the address error will be prompted as soon as the operation is started, but no other button events are correct !!
I don't know where the problem is?

Most of these problems are caused by access before an instance is created.

The upstairs is amazing. I can create a DM form in DPR at the very beginning !!
