Hi Lennnin, Thanks a lot for providing your kind help. But after tweaking registry, yet problem not solved. On yesterday evening when i check again. Same problem occured, what i have done is i have queried one table. Then after Database again giving me the same error. Requesting you to please provide solution to this. That table might contains record more than 5 lakh. And that table is not indexed. So is that a problem ?
