sql 存储过程，号有关问题啊_ASP.NET

sql 存储过程，，号问题啊，急....

SQL code

set ANSI_NULLS ONset QUOTED_IDENTIFIER ONgoCREATE PROC [dbo].[AddAccountInfo](@userName varchar(50),@password varchar(50),@TMStamp bigint,@sync_id int)asbegindeclare @sql varchar(500)set @sql='insert into AccountInfo values('+@userName+','+@password+','+@TMStamp+','+@sync_id+')'             print @sqlend

SQL code

set @sql='insert into AccountInfo values('''+@userName+''','''+@password+''','+@TMStamp+','+@sync_id+')'

@userName和@password是varchar类型，前后应该几个，号啊，怎么老报错啊

SQL code

exec AddAccountInfo 'aa','xx',1,1消息 8114，级别 16，状态 5，过程 AddAccountInfo，第 12 行从数据类型 varchar 转换为 bigint 时出错。

------解决方案--------------------------------------------------------

SQL code

set @sql='insert into AccountInfo values('+@userName+','+@password+','+cast(@TMStamp as varchar(100))+','+cast(@sync_id as varchar(100))+')'

樓上各位都误导LZ了，变量要不要加引号要看情况,不是絕對的，像下面这种情况就要加引号

SQL codeset @sql='insert into AccountInfo values('''+@userName+''','''+@password+''','''+cast(@TMStamp as varchar(100))+''','''+cast(@sync_id as varchar(100))+''')'Exec (@sql)
