私は次のようなストアドプロシージャを持っています
Create proc [dbo].[DNNCentric_TechAnyClass_Course_FilterByCategory]
@CategoryName nvarchar(350)='Business'
AS
BEGIN
Declare @Category nvarchar(350)
Set @Category=""
if(@CategoryName='Business')
begin
Set @Category=@CategoryName
end
select Course.CourseId,Course.CourseTitle,Course.CourseDescription,Category.CategoryName,FormatMaster.FormatType,Teacher.TeacherName
From dbo.DNNCentric_TechAnyClass_CategoryMaster As Category
Inner Join dbo.DNNCentric_TechAnyClass_Course As Course ON Category.CategoryID = Course.CategoryId
Inner Join dbo.DNNCentric_TechAnyClass_FormatMaster As FormatMaster ON FormatMaster.FormatID = Course.FormatID
Inner Join dbo.DNNCentric_TechAnyClass_Teacher As Teacher ON Teacher.TeacherId=Course.TeacherId
Where Category.CategoryName=@Category
END
表示され、エラーが発生します
Msg 1038, Level 15, State 4, Procedure DNNCentric_TechAnyClass_Course_FilterByCategory, Line 6
