   SQLQuery known problems

Last updated on 2002-05-30

Problem: SQLQuery throws an exception when calling a stored procedure using blobs
Solution: Set the BlobTableName to indicate from what table the blobs should be retrieved.
Problem: SQLQuery eats a lot of memory when having large result sets
Solution: This is because the result set is locally cached. If the sets are large you can turn on the CacheToDisk option. This will do the cacheing to a temporary file.
   
Problem When setting the TSQLServer.MaxProcs property to anything but 25 the application allocates approx 50 Mb of extra memory.
Solution: This is a problem with DBLIB. DBLIB allocates this memory regardless of what you set the MaxProcs to. Try to redesign the application so that is uses a maximum of 25 connections by using the TSQLQuery.CacheAllRecords more frequently.
