How to use the SQL Dialect Converter.
Dialect conversion needs attention to functions, dates, quoting and row limits. Mark behavior that cannot be translated directly.
Make the workflow fit your task.
Identify dialect-specific functions, quoting, limits and date behavior, then translate each construct explicitly. Keep the intended row set and ordering visible and flag behavior that needs a target-system decision.
- What you provide
- SQL query, source dialect and target database.
- What you get
- Equivalent query draft with unsupported features flagged.

Illustrative input and output · a teaching example, not a live WebAct run
Example input
PostgreSQL query: SELECT id, name FROM customers ORDER BY id LIMIT 5; Target: SQL Server. Assume id is unique.
Completed example
SELECT TOP (5) id, name FROM customers ORDER BY id; The unique ordering makes the selected first five rows predictable. No other PostgreSQL-specific features occur in this query.
Load this input into the prompt, then copy it to WebAct to try the task. Your result may differ from the illustration.
Decisions and troubleshooting.
Can changing LIMIT to TOP complete every PostgreSQL-to-SQL Server conversion?
No. That handles one construct. Other functions, types and quoting rules may need separate translation and testing.
Why does a converted row-limit query return a different subset?
Use a deterministic ordering appropriate to the data. Without one, a limited result may not identify a predictable set of rows.
