ADO and SQL

[Ranmaru]

I need help with this. I am able to connect to my database, retrieve and insert data, but my problem is.. If in the data like an account name or so there's a ; or ' then I will get an error. I heard about preparing the data, but I couldn't get that to work since I found hardly nothing on it..

I'd be very grateful to you if you were to solve this problem for me and perhaps give me an example of preparing the data that is sent to the SQL database through ODBC using ADO. (ADODB.Connection object)

Using the _SQL.au3 stuff in my signature, I'm not seeing the problem

Yes I see it works by adding another ' before the ', and for some reason I didn't even get errors on the ; this time.

because you are already using ' in to enclose the data you need to double it up when it is part of the data

That is what I don't understand..

' starts the string and ' ends it.. So this is a string data with '

''''

To me that is.. Starting the string, ending it, starting it, ending it.

So are there other characters that can't be used like that and which this character or the same character twice works on?

It's Autoit that is taking it as the end of the string which is why you need to double it up
