SQL Workbench/J is known to work with the following database systems:

• PostgreSQL (Download JDBC driver)
• Oracle (Download JDBC driver)
• Microsoft SQL Server (Download MS driver Download free jTDS driver)
• Firebird SQL (Download JDBC driver)
• MySQL (Download JDBC Driver)
• Apache Derby
• HSQLDB
• H2 Database Engine
• IBM DB2
• McKoi SQL Database
• Ingres R3
• SQLite (with SQLiteJDBC)

Displaying the source for trigger, views, stored procedures and functions is not part of the JDBC API and thus is implemeted through customized SQL queries. If you find that support for this information is missing for your DBMS, please feel free to contact me.

SQL Workbench/J is using primarily standard JDBC API calls and therefore the basic function should work with any DBMS that has a JDBC driver. It also works with ODBC drivers through the JDBC/ODBC bridge, though this is not very performant. But basic queries on e.g. Excel® worksheets do work.
