Question

Database.LoadDataSet无法与SQL Server 2017数据库一起使用。

我们正在将数据库从SQL Server 2008 R2迁移到SQL Server2017。数据库以兼容模式100创建-与SQL Server 2008 R2兼容。我受困于一些旧代码，这些代码不会产生信息丰富的异常。

命令Database.LoadDataSet出现问题，该命令正在调用存储过程，该过程接受2个参数。使用SQL Server 2008 R2可以正常工作，但是使用SQL Server 2017则可以失败，错误是没有足够的SQL参数。但有趣的是，有足够的参数传递。我试图找到一种解决方案，将旧数据库与新数据库进行比较，并且数据库和存储过程的属性似乎相同。

.NET CLR版本：2.0

.NET target Framework版本：3.5

//.NET C# code:
DataSet dataset;
Database db = DatabaseFactory.CreateDatabase();
db.LoadDataSet(
"USP_Proc", 
dataset, 
new string[] {"Titles", "Config", "Teams"}, 
Request.QueryString["Type"], 
int.Parse(Request.QueryString["BranchID"]));


//SQL Procedure:

SET ANSI_NULLS OFF
SET QUOTED_IDENTIFIER ON

ALTER PROCEDURE [dbo].[USP_Proc]
@BranchType VARCHAR (15), @BranchId [dbo].[ID]
AS
SELECT 
  TitleId, Title 
FROM vOperatorTitles
ORDER BY Title

IF @BranchType = 'L'
BEGIN
  SELECT OperatorTeams 
  FROM tCustomerConfig 
  WHERE CustomerId = @BranchId

  SELECT TeamId, TeamName 
  FROM tTeams
  WHERE CustomerId = @BranchId
END

SELECT count(*) as ISSTAGEMANAGEMENT   
FROM tfeature_branch 
WHERE
   branchid=@BranchId and 
   systemside=@BranchType and 
   featureid = (select featureid from tfeature where featurecode= 'somecode')









Expected: there is no errors (as on environments which use old SQL Server)

Actual: 
When calling db.LoadDataSet, there is an error:

[InvalidOperationException: The number of parameters does not match number of values for stored procedure.]

您的参数应该在数组中

db.LoadDataSet("USP_Proc", 
    dataset, 
    new string[] {"Titles", "Config", "Teams"}, 
    new object[] { Request.QueryString["Type"], int.Parse(Request.QueryString        
                  ["BranchID"])});

无效错误：参数数量与存储过程的值数量不匹配
