Sql server 2008 数据库名为变量的动态SQL中的语法错误

可能重复：

在下面的存储过程中，我将数据库名称作为参数传递，但目前用于测试的数据库名称是通过过程中声明的字符串传递的

请告知，我在

SET

语法中出现错误，无法识别我传递的db名称

您的语法有一些问题

不能在INSERT语句中执行集合操作

INSERT INTO @stdb
set @DATAD2 = "SELECT  

不要对动态SQL使用双引号

set @DATAD2 = "SELECT  

应该是

set @DATAD2 = 'SELECT 

FROM '  + @dbName + '.dbo.version v2 

使用+语法时注意间距：

FROM"  + @dbName + ".dbo.version v2 

应该是

set @DATAD2 = 'SELECT 

FROM '  + @dbName + '.dbo.version v2 

以下代码是在mu ssms上解析“成功完成命令”。我已从您的代码中删除所有sysntext错误。希望这有帮助
