Details
After establishing connection to the database, WinSQL tries to
fetch the database catalog. On larger databases, with thousands of
tables, this may take a very long time. Therefore, it is recommended
that you turn this feature off. Following steps show you how to do
that.
Version 6.5 or higher
Using cache is no longer a global option in version 6.5. You can enable or disable catalog fetching per connection.
Steps:
- Start WinSQL - Connection window is displayed
- Un-check "Enable catalog caching"
- Un-check "Load catalog after connection"
Note: If catalog caching is enabled, WinSQL will always load the catalog from the last saved cached value.

Version 6.0 or belowEnabling or disabling
catalog fetching is a global option - meaning if you disable it, WinSQL
won't fetch the catalog for every connection.
Steps:
- Start WinSQL
- Click the Cancel button in the connection window
- Click Edit/Options on the main menu
- Uncheck Fetch catalog after connection
- Reconnect to you database

Refer to the image below, which is a screen shot of WinSQL version 6.5. Connection window for newer versions look similar.
Disadvantage of disabling catalog
Features that depend on the catalog won't work until the catalog is fetched. These features are:
- Intelli-Tips
- Drill down results
To decrease the amount of data returned in the catalog window, try specifying a particular schema/user in the catalog window.
