本文介绍了实体框架:如何运行存储过程并返回值?的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
是否可以使用实体框架执行存储过程,传入变量并返回数据以及返回值?
请不要留下任何代码与实体框架的函数映射。
我已经尝试过这个,我不断得到同样的错误:
以下是我的代码:
SqlParameter Business = new SqlParameter(Business,Search.Term);
SqlParameter Location = new SqlParameter(Location,Search.Location);
SqlParameter PageNumber = new SqlParameter(PageNumber,Search.CurrentPage);
SqlParameter RecordsPerPage = new SqlParameter(RecordsPerPage,Search.RecordsPerPage);
SqlParameter TotalRecords = new SqlParameter(TotalRecords,0);
SqlParameter parm = new SqlParameter()
{
ParameterName =@TotalRecords,
Value = 0,
SqlDbType = SqlDbType.Int,
Direction = System.Data.ParameterDirection.Output
};
var List = db.ExecuteStoreQuery< ENT_SearchBusinessResult>(exec usp_BusinessUser_Search,Business,Location,PageNumber,RecordsPerPage,parm);有没有人知道是什么原因造成的?

$ b 谢谢
编辑:
存储过程代码:
ALTER PROCEDURE [dbo]。[usp_BusinessUser_Search](@Business nVarChar(255)= NULL
,@Location nVarChar(255)= NULL
,@PageNumber Int = 1
,@RecordsPerPage Int = 10
,@TotalRecords Int OUTPUT)
AS
BEGIN
SET NOCOUNT ON;
DECLARE @SQL NVARCHAR(MAX)
,@CacheTable SYSNAME
,@TotalRows Int
,@Category VarChar(255)
,@BusinessCategory Int
,@TownCounty VarChar(50)
,@PcodeTownCounty VarChar(50)
INSERT Voucher_SearchHistory(关键字,位置)
SELECT NULLIF(@Business,'') ,NULLIF(@Location,'')
解决方案帮助:
Is it possible to execute a stored procedure using the Entity Framework, passing in variables and returning data along with a return value?
Please do not leave any code about function mappings with Entity Framework.
I have tried this and I keep getting the same damn error:
Here's my code:
SqlParameter Business = new SqlParameter("Business", Search.Term);
SqlParameter Location = new SqlParameter("Location", Search.Location);
SqlParameter PageNumber = new SqlParameter("PageNumber", Search.CurrentPage);
SqlParameter RecordsPerPage = new SqlParameter("RecordsPerPage", Search.RecordsPerPage);
SqlParameter TotalRecords = new SqlParameter("TotalRecords", 0);
SqlParameter parm = new SqlParameter()
{
ParameterName = "@TotalRecords",
Value = 0,
SqlDbType = SqlDbType.Int,
Direction = System.Data.ParameterDirection.Output
};
var List = db.ExecuteStoreQuery<ENT_SearchBusinessResult>("exec usp_BusinessUser_Search",Business,Location,PageNumber,RecordsPerPage,parm);
Does anyone have any idea what is causing this?
Thanks
EDIT:
Stored procedure code:
ALTER PROCEDURE [dbo].[usp_BusinessUser_Search] ( @Business nVarChar(255) = NULL
, @Location nVarChar(255) = NULL
, @PageNumber Int = 1
, @RecordsPerPage Int = 10
, @TotalRecords Int OUTPUT)
AS
BEGIN
SET NOCOUNT ON;
DECLARE @SQL NVARCHAR(MAX)
, @CacheTable SYSNAME
, @TotalRows Int
, @Category VarChar(255)
, @BusinessCategory Int
, @TownCounty VarChar(50)
, @PcodeTownCounty VarChar(50)
INSERT Voucher_SearchHistory (Keyword, Location)
SELECT NULLIF(@Business,''), NULLIF(@Location,'')
