[mapguide-users] RE: MG and MSSQL performance

[Ivan Miličević]

How can I capture mg generated query?

EP was for query thats is the same one when I select something from C# code (MGQuery.setilter()).

from your earlier comment, do you have spatial indexes in place?

the execution plan was for a non spatial list 100 rows or a captured mg generated query?
