Hello,

I want to batch execute a SQL script prepared by a user on the target system. During execution I want to display progress (execution percentage of script) and also allow a choice of aborting/continuing execution.

How can I do this with MYDAC?
Sinan

Use TMyScript for a script execution.
To calculate progress use StartPos, EndPos, StartLine, EndLine properties in BeforeExecute handler.

These 4 properties are not enough to calculate the whole script progress.
They only give me the position of the current sql statement in the whole script.

What do I set as max value of my progressbar (what is my 100% value)? Myscript.SQL.Count? That value is totally different of what the Final endline is. In my testprogram, I have used a script of 49 statements written in 775 lines and the final endline value turns out to be 2322.
Or do I have to "read" the whole script first (use "ExecuteNext" together with "Omit:= True") first to know what the final EndLine will be, getting the "2322" value and then rerun the whole script (use "ExecuteNext" together with "Omit:= False")? That's the only way I can get a progress bar to work.

Would the implementation of a ReadScript function (to get the final Endline value ) be wise?

Yes, it's right value

Thank you for information. This is bug of MyDAC. We have reproduced and fixed it. This fix will be included in the next MyDAC build.

No, it's not necessary. Now, after bug was fixed, final EndLine value equals to Myscript.SQL.Count - 1.
