Why does the dialect matter?

Different databases have slightly different syntax (e.g. T-SQL's TOP vs MySQL's LIMIT) — picking the right dialect helps the formatter parse dialect-specific syntax correctly.

Will this change the meaning of my query?

No — only whitespace, line breaks, and keyword casing are changed. The query logic and referenced tables/columns stay exactly the same.
