This version of SQL Navigator includes a number of improvements to the Query Builder. Here are a few examples.
The Query Builder window is no longer modal.
You can drag objects into the Query Builder workspace from the DB Navigator tree, from the Find Objects window, or from the Workspace window.
The Add DB Object invokes the standard object selection window
The Add Column command allows adding arbitrary column expressions
Show Column Types command controls the display of column type information in the tables
A join between columns of different types is represented with a dotted line, and join lines now display a hint.
