下面的查询用于创建一个带有服务器名称列表的文本文件。

我遇到的问题是文本文件的创建就像

Server, Server, Server etc.

但我需要它如下

Server
Server
Server

查询：

BEGIN
    CREATE TABLE [TempPSWmiObjectQuery]
                (QueryText nvarchar(max))
END

INSERT INTO [TempPSWmiObjectQuery]

SELECT STUFF((SELECT char(13)+char(10), 
             SUBSTRING(ServerName, 1, 
             CASE WHEN CHARINDEX(',', ServerName) > 0 
                  THEN CHARINDEX(',', ServerName)-1
                  ELSE LEN(ServerName)
             END)
FROM MasterList
FOR XML PATH('')), 1, 1, '')

EXEC sp_configure 'xp_cmdshell', 1;  
RECONFIGURE

EXEC xp_cmdshell 'bcp SQLEnv.dbo.TempPSWmiObjectQuery out "\\ServerName\Data\temp\testlist.txt" -c -T -S "ServerName\Instance"'

EXEC sp_configure 'xp_cmdshell', 0;  
RECONFIGURE

DROP TABLE TempPSWmiObjectQuery

PowerShell 脚本：

        $StagingServer = "ServerName\InstanceName"
        $StagingServerDatabase = "SQLEnv" 

    foreach($line in 
    [System.IO.File]::ReadLines("\\ServerName\Data\temp\testlist.txt")) …

执行下面的查询时，如果我使用PRINT它打印正确。我可以复制并粘贴打印的代码并执行它。但是，如果我使用 EXEC，则会出现以下错误：

有没有办法简化我正在做的事情？为什么 SQLPRINT和 SQL 会EXEC提供这两种截然不同的结果集？

DECLARE @TableName as NVARCHAR(250), @SQL as VARCHAR(MAX);

DECLARE @TableCursor as CURSOR;
SET @TableCursor = CURSOR FOR
SELECT sobjects.name
FROM sysobjects sobjects
WHERE sobjects.xtype = 'U'
AND name like 'HISTORY_MasterList_%'
ORDER BY sobjects.name

OPEN @TableCursor;
FETCH NEXT FROM @TableCursor INTO @TableName;
WHILE @@FETCH_STATUS = 0
BEGIN
SET @SQL ='select '''+ @TableName +''', 0
 Union All
select All ''Server Count'',count(1) from ['+ @TableName +'] 
 Union All
select All ''Server Cores'',sum(convert(decimal(18,0),cores)) …

我想更改我的存储过程，使其不再使用游标来运行。我怎样才能更好地编写这个存储过程？

我正在使用游标编译动态 SQL 以查询我从列表中创建的服务器，以跟踪事务日志备份历史记录。

ALTER PROC [dbo].[spLogBackup]

AS

TRUNCATE TABLE dbo.tLogBackup

DECLARE servers_cursor CURSOR
FOR
select  distinct LinkedserverName
from dbo.Environment
join master..sysservers on srvname COLLATE DATABASE_DEFAULT  = LinkedserverName COLLATE DATABASE_DEFAULT
where LinkedServerName not in ('TestDB')

and ServerUse in ('PROD', 'DR')
and IncludeInstats = 1
order by LinkedServerName

OPEN servers_cursor
DECLARE @Servername varchar(250)

DECLARE @sql varchar(8000)

FETCH NEXT FROM servers_cursor INTO @ServerName
WHILE (@@FETCH_STATUS = 0)
BEGIN
    --Looping throught the servers.
    set @sql = 'insert into dbo.tLogBackup (servername, rundate, runtime, jobname, …
