SELECT, Filtering, Sorting & Pagination

« MySQL Introduction & Data Types« Previous INSERT, UPDATE, DELETE & Upsert (ON DUPLICATE KEY) »Next »

Query records with precision using WHERE conditions, logical operators, wildcard pattern matching, and LIMIT/OFFSET pagination.

Constructing Flexible SELECT Queries

The SELECT statement retrieves rows matching specified criteria. Use WHERE with AND, OR, IN, and BETWEEN operators to target exact subsets of rows.

Filtered Query with Pagination

SELECT UserID, Username, Email, AccountBalance
FROM Users
WHERE AccountBalance > 50.00 AND Username LIKE 'alex%'
ORDER BY AccountBalance DESC
LIMIT 10 OFFSET 20;

Pro Tip

For large tables with millions of rows, avoid deep pagination with large OFFSET values (OFFSET 100000), as MySQL must scan and discard 100,000 rows. Use keyset pagination (WHERE UserID > last_seen_id LIMIT 10) instead.
