有个存储过程里面的错误,时有时无,请进来帮忙看看
有两个sp, 暂且称sp_a, sp_b
sp_a内部call sp_b
跑sp_a的时候
时不时会报以下错误:
column name or number of supplied values does not match table definition
但并不是每次,我用相同的参数,数据库的数据也保证没有任何改动,就是有时候会报错,有时候不会
错误是从sp_b内部报的,
单独跑sp_b又总是好的
[解决办法]
赋值的数量与你的表列数不同,因有时会执行到新增有时不会,因此有时错,有时不错
看下你插入的语句就知道了
[解决办法]
call sp_b?
MYSQL?
[解决办法]
第一种方法: 使用output参数USE AdventureWorks;GOIF OBJECT_ID ( 'Production.usp_GetList', 'P' ) IS NOT NULL DROP PROCEDURE Production.usp_GetList;GOCREATE PROCEDURE Production.usp_GetList @product varchar(40) , @maxprice money , @compareprice money OUTPUT , @listprice money OUTAS SELECT p.name AS Product, p.ListPrice AS 'List Price' FROM Production.Product p JOIN Production.ProductSubcategory s ON p.ProductSubcategoryID = s.ProductSubcategoryID WHERE s.name LIKE @product AND p.ListPrice < @maxprice;-- Populate the output variable @listprice.SET @listprice = (SELECT MAX(p.ListPrice) FROM Production.Product p JOIN Production.ProductSubcategory s ON p.ProductSubcategoryID = s.ProductSubcategoryID WHERE s.name LIKE @product AND p.ListPrice < @maxprice);-- Populate the output variable @compareprice.SET @compareprice = @maxprice;GO另一个存储过程调用的时候:Create Proc TestasDECLARE @compareprice money, @cost money EXECUTE Production.usp_GetList '%Bikes%', 700, @compareprice OUT, @cost OUTPUTIF @cost <= @compareprice BEGIN PRINT 'These products can be purchased for less than $'+RTRIM(CAST(@compareprice AS varchar(20)))+'.'ENDELSE PRINT 'The prices for all products in this category exceed $'+ RTRIM(CAST(@compareprice AS varchar(20)))+'.'第二种方法:创建一个临时表create proc GetUserNameasbegin select 'UserName'endCreate table #tempTable (userName nvarchar(50))insert into #tempTable(userName)exec GetUserNameselect #tempTable--用完之后要把临时表清空drop table #tempTable--需要注意的是,这种方法不能嵌套。例如: procedure a begin ... insert #table exec b end procedure b begin ... insert #table exec c select * from #table end procedure c begin ... select * from sometable end --这里a调b的结果集,而b中也有这样的应用b调了c的结果集,这是不允许的,--会报“INSERT EXEC 语句不能嵌套”错误。在实际应用中要避免这类应用的发生。第三种方法:声明一个变量,用exec(@sql)执行:1);EXEC 执行SQL语句declare @rsql varchar(250) declare @csql varchar(300) declare @rc nvarchar(500) declare @cstucount int declare @ccount int set @rsql='(select Classroom_id from EA_RoomTime where zc='+@zc+' and xq='+@xq+' and T'+@time+'=''否'') and ClassroomType=''1''' --exec(@rsql) set @csql='select @a=sum(teststucount),@b=sum(classcount) from EA_ClassRoom where classroom_id in ' set @rc=@csql+@rsql exec sp_executesql @rc,N'@a int output,@b int output',@cstucount output,@ccount output--将exec的结果放入变量中的做法 --select @csql+@rsql --select @cstucount本文来自CSDN博客,转载请标明出处:http://blog.csdn.net/fredrickhu/archive/2009/09/23/4584118.aspx--这是集中存储过程调用存储过程的方法,楼主看看你的调用正确吗

贴出代码,猜起来多累
insert语句写法要规范,列出字段列表
