Enter a table name
Visual SQL query builder for SELECT and DELETE operations. Add fields, conditions, ordering, and pagination to generate clean SQL queries.
What is SQL Query Builder?
SQL Query Builder generates SQL statements through a visual interface instead of manual coding. Add fields to select, define WHERE conditions with multiple operators, set ORDER BY sorting, and configure LIMIT/OFFSET for pagination. Perfect for developers learning SQL, building complex queries, or generating statement templates without syntax errors.
How to Use
- Choose operation: SELECT or DELETE
- Enter table name
- Add fields with optional aliases (SELECT)
- Add WHERE conditions with operators (=, !=, LIKE, etc.)
- Set ORDER BY for sorting results
- Configure LIMIT and OFFSET for pagination
- Copy generated SQL to your database client
Why Use This Tool?
Tips & Best Practices
- Always use WHERE with DELETE to avoid deleting all rows
- LIKE operator for pattern matching with %
- IS NULL checks for missing values
- BETWEEN for range filtering
- Aliases make output column names readable
- ORDER BY sorts results for consistent order
Frequently Asked Questions
What SQL operations are supported?
SELECT (retrieve data) and DELETE (remove data). SELECT supports fields, WHERE conditions, ORDER BY, LIMIT, and OFFSET. DELETE supports WHERE conditions for targeted deletion. INSERT and UPDATE require different form structures.
What operators are available?
Comparison: =, !=, <, >, <=, >=. Pattern: LIKE (with % wildcards), IN, NOT IN. Null checks: IS NULL, IS NOT NULL. Range: BETWEEN. These cover most common filtering needs.
How do WHERE conditions work?
Each condition filters rows. Multiple conditions connect with AND (all must be true) or OR (any can be true). First condition has no connector; subsequent conditions add AND/OR before the condition. Complex logic may need parentheses.
What's the difference between LIMIT and OFFSET?
LIMIT restricts result count (e.g., LIMIT 10 returns max 10 rows). OFFSET skips rows before returning (e.g., OFFSET 5 LIMIT 10 returns rows 6-15). Together they enable pagination: page 2 is OFFSET 10 LIMIT 10.
How do I use LIKE for pattern matching?
LIKE matches text patterns with % wildcards. 'text%' matches anything starting with 'text'. '%text' matches ending with 'text'. '%text%' matches containing 'text'. Use WHERE name LIKE '%john%' to find names containing 'john'.
Can I use this for production queries?
Yes - generated SQL is standard syntax. However, verify queries before executing DELETE statements. For INSERT/UPDATE or complex joins, extend manually or use database IDEs. This builder handles common SELECT/DELETE patterns efficiently.
