1、查看数据库表数量
SELECT count(TABLE_NAME) FROM information_schema.TABLES WHERE TABLE_SCHEMA='dbname';
SELECT count(TABLE_NAME) FROM information_schema.TABLES WHERE TABLE_SCHEMA='dbname';
2.获取mysql下所有数据库表的数量
SELECT COUNT(*) TABLES, table_schema FROM information_schema.TABLES GROUP BY table_schema;
3.获取指定数据库的表的数量
SELECT COUNT(*) TABLES, table_schema FROM information_schema.TABLES
WHERE table_schema = '数据库名' GROUP BY table_schema;
