主题:sql嵌入VC存储过程返回值
要编两个存储过程实现如下的功能
EXEC SQL declare @cnt int;
EXEC SQL exec ge_number @cnt output; //取出参数
再让MNumber=cnt //再将取出的参数赋值给全局变量MNumber
EXEC SQL EXEC table_name :stable,:MNumber; //再在另外一个存储过程里面实现表名,参数都是变量的查询
基于此,如下编写的两个存储过程要怎么修改啊
int stable,MNumber; //全局变量
EXEC SQL CREATE Procedure table_name
@tablename char([color=#800000; font-weight: bold]10[/color]),@ID int
As exec('insert into ' +@tablename+ ' values(' +@ID+ ',1,1,1,1,1,1,1,1,1,1)'); //[color=#800000; font-weight: bold]1[/color]
EXEC SQL CREATE Procedure ge_number
@table nvarchar([color=#800000; font-weight: bold]50[/color]),
@cnt int output
AS
declare @sql nvarchar([color=#800000; font-weight: bold]100[/color])
set @sql=N'select @cnt=number into :MNumber from '+@table
exec sp_executesql @sql ,N'@cnt int output' , @cnt output; //[color=#800000; font-weight: bold]2[/color]
