Thank BigChimp, but I do not think that this is a new question, because it's goal is to do exacly the same thing as mentioned in topic, sorry if Im wrong.
I tried executing it in flamerobin and it worked like it should have. It added data about client to database.
Sorry, but because I have so little knowledge of Delphi I have no Idea how to answer about .SQL.Text. I think its empty because after starting application I immidiately use Button to execute procedure.
If INSERT INTO KLINSERT if wrong, what should I use to execure procedute to pass data from edit boxes to DB?
Sorry again if this is wrong topic or thread to ask these questions. But didn't wanted to have two threads about the same thing by the same person.
Thanks
