mysql和sqlserver查询数据库表的数量方法详解

SELECT COUNT(*) TABLES, table_schema FROM information_schema.TABLES GROUP BY table_schema;

SELECT COUNT(*) TABLES, table_schema FROM information_schema.TABLES WHERE table_schema = '库名';

SELECT count(*) FROM sys.objects WHERE type='U'   --统计表数量
SELECT NAME  FROM sys.objects WHERE type='U'      --列出表名称
或者
SELECT COUNT(*) FROM SysObjects Where XType='U'   --统计表数量
SELECT Name FROM SysObjects Where XType='U'       --列出表名称

SELECT  ROW_NUMBER() OVER (ORDER BY All_Table.NAME) AS NO, 
            All_Table.NAME AS '表名(EN)',
            CONVERT(NVARCHAR(100),ISNULL(TableDesc.[VALUE],'-')) AS '表名(CN)',
            TabIndex.ROWS AS '记录数'
            FROM SYS.TABLES All_Table 
LEFT JOIN SYS.EXTENDED_PROPERTIES TableDesc ON (All_Table.OBJECT_ID = TableDesc.MAJOR_ID AND TableDesc.MINOR_ID = 0)--取表的名称两个条件
INNER JOIN SYSINDEXES TabIndex ON All_Table.OBJECT_ID=TabIndex.ID AND TabIndex.INDID < 2 
WHERE 1=1
 ORDER BY TabIndex.ROWS DESC
