Frequently Asked Questions

Does formatting change what the query does?

No. Only whitespace, line breaks and keyword casing change. The parsed statement is identical, so results and the execution plan are unaffected.

Why does the dialect matter?

Because identifier quoting and reserved words differ — MySQL uses backticks, PostgreSQL and standard SQL use double quotes, SQL Server uses square brackets. Picking the right dialect avoids mangling identifiers.

Should SQL keywords be uppercase?

It is a strong convention because it separates language from identifiers at a glance, which matters in long queries. SQL itself is case-insensitive for keywords, so it is purely a readability choice.

Can it format stored procedures?

Basic procedural blocks format reasonably. Deeply nested dialect-specific procedural code — PL/pgSQL, T-SQL control flow — may need manual tidying afterwards.
