Sql server 在sql server 2008中执行动态查询以从表@tblName='；获取的完整名称时出错；客户列表'；

当我通过这个执行这个动态查询时，我试图获取客户的全名

（名字+姓氏）

请让我知道我做错了什么

代码如下：

 Set @tblName ='Customer_List'
    Exec (N'Select First_Name'+' '+'Last_Name from'''+ @tblName+'''
                 where Customer_Id in ('+ 'cast(1000 as nvarchar(10))' );      

我得到这个错误：

 (1 row(s) affected)
                        Msg 102, Level 15, State 1, Line 1
                        Incorrect syntax near 'dbo.Customer_List'.
                        Msg 102, Level 15, State 1, Line 1
                        Incorrect syntax near 'dbo.Customer_List'.
                        Msg 102, Level 15, State 1, Line 1
                        Incorrect syntax near 'dbo.Customer_List'.
                        Msg 102, Level 15, State 1, Line 1
                        Incorrect syntax near 'dbo.Customer_List'.
                        Msg 102, Level 15, State 1, Line 1
                        Incorrect syntax near 'dbo.Customer_List'.
                        Msg 102, Level 15, State 1, Line 1
                        Incorrect syntax near 'dbo.Customer_List'.

试试这个

Set @tblName ='Customer_List' Exec (N'Select First_Name'+' '+'Last_Name from '+ @tblName+' where Customer_Id in ( cast(1000 as nvarchar(10) ))' );

试试这个
1） 在中的

之后添加空格

2） 将
）
括号添加到
（10））


3） 删除表名周围的
'
。

DECLARE @tblName AS VARCHAR(100)

 Set @tblName ='TempTable'
    Exec (N'Select First_Name'+' '+'Last_Name from '+ @tblName+'
                 where Customer_Id in ('+ 'cast(1000 as nvarchar(10)))' );

尝试以下查询：

DECLARE @sql as VARCHAR(1000)
SET @sql = 'Select First_Name + '' ''+ Last_Name from '+ @tblName + ' where Customer_Id in (' + CAST(1000 AS VARCHAR(1000)) + ')'
Exec (@sql)

调试动态sql时，您应该做的第一件事是打印sql字符串，以便查看要执行的操作。错误通常会变得非常明显。
