01 · Database-aware assistance

Write SQL faster—and inspect what assisted you

AutoComplete reduces manual typing while you build SQL statements. The SQL JasonQuery sends to the connected database for supported assistance workflows remains visible in SQL History.

  • Database-aware suggestions
  • Useful for longer, object-rich SQL
  • Supporting SQL remains inspectable

02 · Reusable SQL

Turn short keywords into complete SQL snippets

AutoReplace expands configured keywords into longer SQL snippets or templates. Type a keyword and press Space to reuse anything from a short clause to a multi-line query fragment.

  • User-configured shortcuts
  • Single-key expansion
  • Short clauses or multi-line templates

03 · Safety and transparency

Important database activity should not be hidden.

JasonQuery keeps transaction decisions explicit and preserves a visible record of SQL sent through supported application workflows.

Pending-transaction reminder

Stay aware of pending transactions

When a transaction remains pending, JasonQuery periodically reminds you instead of silently committing database changes.
