Solution 2

Dont make too many objects running in loop. It will eat the memory allocated by the memory allocator . As you run out of memory you get exception, make sure you close all readers and adapters.

Solution 1

Did you translate the message correctly?
I think you open a connection for every update query, and do not close it afterwards. Call the Dispose() method of the connection object, or use using statements.

If it is like that, why it updates records for first 50 odd records. m having trouble to understand, in my case it works fine from ID 323 to 378,,,,,,,,,

Because the number of connections to the database is limited. Learn some basics!
