问题描述

我在sql中有一个表，其设计是：

I have a table in sql whose design is :

Name varchar(100) ,
DateAndTime datetime,
Price int
Discount int

我想写一个存储过程，其中表名作为输入给出

并通过该查询记录插入。

i尝试过很多但却失败了:(

I want to write a stored procedure in which table name is given as an input
and through that query record get inserted.
i have tried many things but failed :(

DECLARE @Sql NVARCHAR(MAX);

SET @Sql = N'insert into'+
              QUOTENAME(@tableName)+
          + 'values' + '(' + @a + ',' + CONVERT(varchar(20), @b,101) + ',' + convert(varchar(100), @c,101) +',' +convert(varchar(100), @d,101) +')'

 EXECUTE sp_executesql @Sql

请帮助!!!!

推荐答案

你可以使用参数 sp_executesql

you can use parameters with sp_executesql

SET @Sql = N'insert into'+
              QUOTENAME(@tableName)+
          + 'values(@a,@b,@c,@d)'

EXECUTE sp_executesql @Sql, 
            N'@a nvarchar(100), @b datetime, @c int,@d INT',
            @a,@b,@c,@d

很难用不同类型的数据值构建sql语句，特别是日期时间类型。使用参数并让数据库服务器完成其余的工作:)



您需要了解更多关于 sp_executesql 的信息？然后关注这些资源

it is difficult to build sql statement with different types of data values, specially datetime types. use parameters and let the database server to do the rest :)
