如何使这项工作？ [英] How to make this work?

问题描述

目前我已经开始创建一个过程，该过程获取参数，并且应该在一定条件下将一个表的内容复制到另一个表。我在这里复制了代码。它编译好。但没有任何影响。

Currently I have started creating a procedure, which gets the parameters and should copy the contents of one table to another with certain conditions. I have copied the codes here. It compiles good. But nothing is affected.

ALTER PROCEDURE sp_ArchiveTable1(
@StartDate datetime,
@EndDate datetime,
@DateColumn VARCHAR(100),
@TableName VARCHAR(100),
@NewTableName VARCHAR(100)
)
AS
DECLARE @NextIDs TABLE(UniqueID int primary key)
 SELECT * INTO [@NewTableName] FROM [@TableName] 
WHERE [@DateColumn] >= @StartDate AND [@DateColumn] <= @EndDate

推荐答案

请参阅此文章：在存储过程中构建动态SQL [ ^ ]

Please, see this article: Building Dynamic SQL In a Stored Procedure[^]

试试这个：

Try this:

ALTER PROCEDURE sp_ArchiveTable1(
	@StartDate datetime,
	@EndDate datetime,
	@DateColumn VARCHAR(100),
	@TableName VARCHAR(100),
	@NewTableName VARCHAR(100)
)
AS
BEGIN
	DECLARE @NextIDs TABLE(UniqueID int primary key)
	DECLARE @statement nchar(1000) = N'SELECT * INTO '+@NewTableName+' FROM '+@TableName+' 
	WHERE '+@DateColumn+' BETWEEN '''+CONVERT(VARCHAR(100), @StartDate)+''' AND '''+CONVERT(VARCHAR(100), @EndDate)+''''
	PRINT @statement
	EXEC sys.sp_ExecuteSQL @statement
END
go

但是你必须要小心 SQL注入 [ ^ ]。

But you''ll have to be careful about SQL injection[^].
See SQL Injection: What is it?[^]

--Amit

我认为你必须使用exec（这里是你的查询）命令来执行此操作。



希望这有帮助......

I think you have to use exec(here your query) command for this to get executed.

Hope this helps...
