What Query Browser tools are out there available for Sybase Database?
As Sybase also has a JDBC driver any Java/JDBC tool should work too (at least the basic stuff).

These are the free JDBC based tools that I know of:


DbVisualizer  (not open source, but has a free version)
ExecuteQuery
SQL Developer That's not the one from Oracle! It's not open source but free as well
SQL Workbench/J
Squirrel has already been mentioned.


Another commercial tool that comes to my mind is: DB Solo
