Changed the Cursor mode to Server from Client in the SQL query tab

Below is information about the setting

Allows you to select Server or Client and manage the cursor.

Disadvantage: Reduces performance when the net-traffic increases.
Transfers the record set to the client machine by ADO and manage the cursor there.
Advantage: Better performance.
Disadvantage: The results are buffered, depend on ADO provider and can hide real database performance.
