What this tool helps you do

When it is useful
- Reviewing a complex SELECT
- Making joins and filters visible
- Preparing a query for code review

A practical example
Format a report query and inspect each JOIN condition and WHERE predicate. Confirm that an outer join has not been unintentionally turned into an inner join by a later filter.
Limitations and common mistakes
SQL dialects differ in quoting, functions, pagination, and operators. Never run unknown statements with write privileges, and inspect query plans before using expensive queries on production data.
