How can I open multiple SQL Worksheets? Can I open multiple worksheets in a Document Tab, for example?
Just keep opening worksheets, right-click on a connection, or use Tools > SQL Worksheet, the toolbar buttons, or ctrl+shift+n.
Each worksheet is it's own document. You can create multiple document tab groups if you want to see and work on multiple worksheets concurrently.
