在使用桦仔的分享一个SQLSERVER脚本（计算数据库中各个表的数据量和每行记录所占用空间）的脚本时，遇到下面一些错误
这个是因为这些表的Schema是Maint，而不是默认的dbo，造成下面这段SQL在执行EXEC sp_spaceused @tablename时出现
Msg 15009, Level 16, State 1, Procedure sp_spaceused, Line 75
The object ‘xxxx‘ does not exist in database ‘YourSQLDba‘ or is invalid for this operation.
DECLARE Info_cursor CURSOR
FORSELECT ‘[‘ + [name] + ‘]‘
FROM sys.tablesWHERE type = ‘U‘;
OPEN Info_cursor FETCH NEXT FROM Info_cursor INTO @tablename
WHILE @@FETCH_STATUS = 0 BEGIN INSERT INTO #tablespaceinfo EXEC sp_spaceused @tablename FETCH NEXT FROM Info_cursor
INTO @tablename END 修正后的脚本如下所示
CREATE TABLE #tablespaceinfo
(
nameinfo VARCHAR(500) ,rowsinfo BIGINT ,
reserved VARCHAR(20) , datainfo VARCHAR(20) , index_size VARCHAR(20) , unused VARCHAR(20))
DECLARE @tablename VARCHAR(255);

FORSELECT ‘[‘ + s.[name] +‘]‘ +‘.‘ + ‘[‘ + t.[name] + ‘]‘
FROM sys.tables tINNER JOIN sys.schemas s ON t.schema_id = s.schema_id
WHERE type = ‘U‘;
OPEN Info_cursor FETCH NEXT FROM Info_cursor INTO @tablename
WHILE @@FETCH_STATUS = 0 BEGIN INSERT INTO #tablespaceinfo EXEC sp_spaceused @tablename FETCH NEXT FROM Info_cursor
INTO @tablename END CLOSE Info_cursor DEALLOCATE Info_cursor --创建临时表
CREATE TABLE [#tmptb]
(
TableName VARCHAR(50) ,DataInfo BIGINT ,
RowsInfo BIGINT ,
Spaceperrow AS ( CASE RowsInfo
WHEN 0 THEN 0
ELSE CAST(DataInfo AS decimal(18,2))/CAST(RowsInfo AS decimal(18,2))
END ) PERSISTED)
--插入数据到临时表
INSERT INTO [#tmptb]( [TableName] ,
[DataInfo] ,
[RowsInfo]
)
SELECT [nameinfo] ,CAST(REPLACE([datainfo], ‘KB‘, ‘‘) AS BIGINT) AS ‘datainfo‘ ,
[rowsinfo]
FROM #tablespaceinfoORDER BY CAST(REPLACE(reserved, ‘KB‘, ‘‘) AS INT) DESC
--汇总记录
SELECT [tbspinfo].* ,[tmptb].[Spaceperrow] AS ‘每行记录大概占用空间（KB）‘
FROM [#tablespaceinfo] AS tbspinfo ,
[#tmptb] AS tmptbWHERE [tbspinfo].[nameinfo] = [tmptb].[TableName]ORDER BY CAST(REPLACE([tbspinfo].[reserved], ‘KB‘, ‘‘) AS INT) DESC
DROP TABLE [#tablespaceinfo]
