Question 1

What SQL snippets are available in the library?

Accepted Answer

The SQL Snippets Library covers 10+ categories: Recursive CTEs (hierarchical queries, date ranges), Window Functions (ROW_NUMBER, RANK, LAG/LEAD, running totals), Pagination (OFFSET/FETCH, ROW_NUMBER wrapper), Pivot Tables (CASE-based and standard PIVOT), Slow Query Analysis (EXPLAIN patterns, missing indexes, blocking queries), String Aggregation (GROUP_CONCAT, STRING_AGG, LISTAGG), Date/Time queries, Common Table Expressions, MERGE/UPSERT patterns, and more. New snippets are added regularly.

Question 2

Is the SQL snippets library free to use?

Accepted Answer

Yes, completely free. All snippets are accessible without any account, signup, or payment. Each snippet includes a description and ready-to-use SQL code that you can copy with a single click. No limits on how many snippets you can view or copy.

Question 3

Which SQL dialects do the snippets support?

Accepted Answer

Snippets are written in standard SQL and include dialect-specific variations where applicable (e.g., STRING_AGG for PostgreSQL vs GROUP_CONCAT for MySQL, LISTAGG for Oracle). Each snippet's description notes which dialects it targets. Most snippets work across PostgreSQL, MySQL, SQL Server, SQLite, and Oracle with minor adjustments.

Question 4

Can I contribute or request new SQL snippets?

Accepted Answer

The library is maintained by the SQLFormat.io team and updated regularly. If you have a specific SQL pattern you'd like added, feel free to reach out. The tool runs entirely client-side with no server storage, so new snippets are added through site updates.
