Frequently asked questions
Does this tool run SQL?＋
No. It compares SQL as text and never connects to a database.
Can I compare stored procedures?＋
Yes. Paste or open both procedure versions like any other SQL script.
Is SQL uploaded?＋
No. It stays in memory in the current browser tab.
More comparison tools are coming
PDF, Word, Excel, and image comparison are planned for a future release. They are not part of this version, and there are no inactive buttons pretending otherwise.
