You're right mdaems ! I've tried again, and refresh currently refreshes the entire dataset, just like close-open.

Thank You.

Could somebody tell me what is the difference between Refresh and Close-Open? Actually i would like to know which is better for ZReadOnlyDataset's refreshing.

Could somebody answer to this question? I'm curious too.

Thanks. So this is confirm me to use my own SQL-statements.

Thank you.

If it is the same in fact, i remain at normal SQL statements, it think this is a littlebit easier.
But doesn't it produce more SQLs for all kind of sure things and checkings when it generate automaticly?

In which cases doesn't work the automatic generating?

Which is better? Which is faster? Why?

1.
Using the dataset's insert, edit , post and delete procedures
OR
setting directly the SQL property and then call execsql?

2.
Using master-detail arrangement
OR
refresing the dataset in the other table's afterscroll event?

I have a ReadOnlyQuery with date fields. Some of the fileds are NULL. When is call Refresh, i get an error message (see below). But when i call Close, and then Open, i don't get the error. Why is that? What's the difference? And it stopped here in unit ZDbcMySqlResultSet: [php] function TZMySQLResul...

Sorry, it was a recursive calling.

Why do i get a "Stack overflow" error message after compiling and building? Compile and build are OK by themselves, but when i run the application as normal running from command line, it dont want to run. When i run it by Delphi's Run button, it sopts at procedure TZRowAccessor.CheckColumn...

Thank You!
So, i remain at ZQuery.

Sorry for the question, but i have to ask it.

Which is the better? Which is smarter? Your ZQuery or Jedi's JvQuery?
