Hi @Rupali_Shinde,
The first thing I would suggest is an update to Database 1.10.0 (just to rule out any bugs that might have been fixed in the meantime).
Then, I would double-check the connection string and the provided set in the Connect activity. Are you maybe using a pre-configured DNS in your connection string, and that DNS is referring to the 32-bit driver?
If possible, it would help if you could share your connection string without the sensitive information (please mock up any sensitive info).
