hi
I have a Query ( TUniQuery ) and I should refresh it repeatedly and after refresh I should copy its data on a Memory-table

I use RefreshQuick(True) method of UniQuery but I want to know the new data have any changed rows or not , if there is changed rows , I do copying otherwise no copy !

Is it possible ? and how ?

I set the StrictUpdate to True and try to get RowAffected value after RefreshQuick method , but sometimes I know that there is no changes in table but RowAffected return 1 ( or 0 ) and many times ! I know there is some changes on table but , RowAffected returns 0 !

How it works ?

thanks ...

Please specify the database you are working with.

I am using MySQL (InnoDB)

You can use the RowsAffected property to retrieve the number of rows affected by the modify query. It returns the number of rows changed, deleted, or inserted by the LAST STATEMENT if it was an UPDATE, DELETE, or INSERT.
If you want to use the RowsAffected property after execution of the RefreshQuick method for accurate retrieving of the number of records affected on the server, please post a suggestion at our user voice forum: h[url]ttp://devart.uservoice.com/forums/104635-delphi-data-access-components/category/18939-unidac[/url] . If the suggestion gets a lot of votes, we will consider the possibility to implement it.
