SeedCode ( has released SQL Explorer, which lets you write SQL Queries using a wizard made up of FileMaker dialogs you probably already know.

You can write queries against your own tables, then copy and paste the resulting queries right into your FileMaker 12 files with all the correct calculation syntax, or export the query results to Excel for ad hoc reporting.

SQL explorer is completely unlocked for you to modify and extend. This means you can create and save your own library of queries.
