SQL Diff Checker — Compare SQL Queries & Schemas
Quick Answer: Paste two SQL files or queries to see line-by-line differences. Useful for comparing schema versions, reviewing migration scripts, and finding changes in stored procedures or complex queries.
FAQ
Can this compare database schemas?
It compares the text of SQL files. For structural schema comparison (ignoring formatting), use dedicated tools like pgdiff or mysql-diff that understand SQL semantics.
How do I compare two versions of a migration?
Paste the previous migration SQL on the left and the new version on the right. The diff shows exactly what statements were added, modified, or removed.
