【SQL】统计所有表的行数

原文: 【SQL】统计所有表的行数

环境：mssql ent 2k8 r2

原理：遍历所有用户表，用sp_spaceused过程分别获取每张表的行数并写入临时表，最后返回临时表

IF OBJECT_ID('tempdb..#TableRowCount','U') IS NOT NULL DROP TABLE #TableRowCount GO

CREATE TABLE #TableRowCount (Name sysname PRIMARY KEY, RowCnt DECIMAL(11,0), Reserved VARCHAR(18), Data VARCHAR(18), Index_Size VARCHAR(18), Unused VARCHAR(18)) GO

DECLARE curCntAllTableRows CURSOR LOCAL FAST_FORWARD FOR

        SELECT name FROM sys.tables OPEN curCntAllTableRows DECLARE @TableName sysname FETCH NEXT FROM curCntAllTableRows INTO @TableName

WHILE @@FETCH_STATUS=0

BEGIN

 INSERT INTO #TableRowCount EXEC sys.sp_spaceused @TableName

 FETCH NEXT FROM curCntAllTableRows INTO @TableName

END

CLOSE curCntAllTableRows DEALLOCATE curCntAllTableRows SELECT Name,RowCnt FROM #TableRowCount WHERE RowCnt>0

ORDER BY RowCnt DESC,Name

文毕。
