Dear Craig Thank you for your help. In my program (and problem) I created couple of empty tables in the same way as you proposed in the "Create Only" case in envlosed example. This should create only empty tables and there is no time spend on transferring the data. And this is which turned up to take more time then the vi execution. I believe that it can be caused by several reasons. The DB tools works on CINs, on top of it, communicated with SQL engines (I use JET 4). It could be like the engine release control to CINS but still is dooing some job with OS to create a table, reserve resources etc. If the system is loaded, which could be my case, the table creation takes long time.
The idea with while loop gives me another idea to use it while querring the database. Immediatelly after the creation I can build the while loop which continues as long as the error occurs and stopes after the No error or timeout. That could solve my problems, I guess. kind regards Pawel
