Description:
Crystal Reports fails with error when connecting to MySQL using MyODBC and the connection option=3147779 (1 + 2 + 2048 + 1048576 + 2097152)

1	Don't Optimized Column Width	
2	Return Matching Rows
2048	Use Compressed Protocol
1048576	Don't Cache Result (forward only cursors)
2097152	Force Use Of Forward Only Cursors
