mysql list all tables with sizes

If you ever wants to who all your tables ordered by table size. use this snippet:


SET @DBNAME = "test_development"; #database name

SELECT CONCAT(table_name) AS "Tables",
 CONCAT(ROUND(table_rows / 1000000, 2), 'M') rows,
 CONCAT(ROUND(data_length / ( 1024 * 1024 * 1024 ), 2), 'G') DATA,
 CONCAT(ROUND(index_length / ( 1024 * 1024 * 1024 ), 2), 'G') idx,
 CONCAT(ROUND(( data_length + index_length ) / ( 1024 * 1024 * 1024 ), 2), 'G') total_size,
 ROUND(index_length / data_length, 2) idxfrac
FROM information_schema.TABLES
WHERE table_schema = @DBNAME
ORDER BY data_length + index_length DESC;
