FAQ
Do I need a database connection to use this builder?
No. This is a 100% offline, client-side builder. You type your table names and column names directly (or import a JSON schema) and the builder generates SELECT SQL on the fly. Nothing is ever sent to a server — there is no live DB connection, no execution, and no credentials to enter.
Which SQL clauses can I build visually?
SELECT (with DISTINCT and column aliases), FROM (with table aliases), INNER/LEFT/RIGHT/FULL JOIN with ON conditions, WHERE (multiple predicates joined by AND/OR with operators =, !=, <, >, <=, >=, LIKE, IN, IS NULL, IS NOT NULL, BETWEEN), GROUP BY, HAVING, ORDER BY (ASC/DESC), LIMIT and OFFSET.
Which SQL dialects are supported and how does quoting change?
ANSI (double-quotes), MySQL/MariaDB (backticks), PostgreSQL (double-quotes), SQLite (double-quotes), and SQL Server (square brackets). The builder auto-quotes reserved words and identifiers containing spaces. LIMIT/OFFSET is emitted as standard SQL for all supported dialects.
Can I use aggregates like COUNT, SUM, AVG, MIN, MAX?
Yes. Every selected column supports an optional aggregate function and alias. When aggregates are present, non-aggregated columns are automatically included in the GROUP BY clause so the generated SQL is valid. HAVING predicates let you filter on aggregate results.
What extras does this builder offer versus others?
(1) Five dialect presets with auto-quoting. (2) Aggregates + automatic GROUP BY inference. (3) Multi-predicate WHERE with AND/OR. (4) Four JOIN types with ON-condition editor. (5) ORDER BY multi-column. (6) DISTINCT, LIMIT, OFFSET. (7) Reserved-word detection. (8) Schema JSON import. (9) Live validation with inline warnings. (10) localStorage history (max 20). (11) Shareable URL. (12) Copy / download .sql. (13) Three example query presets.
