            }

        }

所有的 SQL 语句都作为错误返回，SQL 自然不允许重复的表，所以我试图在尝试错误处理时调用此 SQL 过程，以便在未创建表的情况下将数据添加到已经存在的表中。

所以发生的事情是我正在复制一个表，然后用 sp_rename 重命名该表，如果该表不存在，这可行，但如果它存在，它将出错，所以在出现错误时，我只想将一个表中的所有数据插入另一个表但由于某种原因，它无法正常工作，SQL 过程一直说 INTO 语句是语句错误。需要帮忙！！谢谢

我相当确定您正在寻找的语法更像是这样的：

SELECT * INTO table FROM othertable

我认为这是正确的代码：

ALTER PROC spTransferDat
@TableName nvarchar(50)
AS
if OBJECT_ID(@TableName) is null
  EXEC('SELECT * INTO [' + @TableName + '] FROM ClientGroups');
else 
  EXEC('insert INTO [' + @TableName + ']  select * FROM ClientGroups');
