Question

我想使用let levelSelection = UserDefaults.standard.integer(forKey: "LevelSelection") let scene = levels[levelSelection - 1]创建以下存储过程：

DbContext

我想通过使用

扩展

CREATE PROCEDURE upGetTestID 
     @WOID NVARCHAR(60), 
     @SampleID NVARCHAR(60),
     @Analyte NVARCHAR(60)
AS
    SELECT TestID
    FROM tblWOSampleTest
    JOIN tblTest ON tblTest.TestID = tblWOSampleTest.TestID 
    WHERE @WOID = tblWOSampleTest.WOID 
      AND @SampleID = tblWOSampleTest.SampleID 
      AND @Analyte = tblTest.Analyte
GO

类来创建上述存储过程

DbContext

Answer 1

将参数放在第一个括号中。创建存储过程，然后通过Entity Framework连接到数据库。当您想要从数据库创建上下文文件时，您将看到包含表，视图和存储过程的选项。你也会在那里看到这个存储过程。然后按照link

进行操作

CREATE PROCEDURE [upGetTestID]
    (@WOID nvarchar(60),
     @SampleID nvarchar(60),
     @Analyte nvarchar(60)) 
AS 
BEGIN
    SELECT TestID  
    FROM tblWOSampleTest
    JOIN tblTest ON tblTest.TestID = tblWOSampleTest.TestID  
    WHERE @WOID = tblWOSampleTest.WOID 
          AND tblWOSampleTest.SampleID = @SampleID 
          AND tblTest.Analyte = @Analyte 
END
