如何从存储过程中获取结果作为值？

Question

I had a similar question last week where I got good help so I'm trying again.

Basically I have this stored procedure where I input a string and get out an int from a table in the database. I would like to use this int for another stored procedure.

The problem is I don't know how to just get the actual value from my stored procedure result. If I wanted to I could show the output in a datagrid or something, but I don't want that. I just want the value in my program to be used for something else. How do I do this?

Here is the SP:

@EquipmentTypeDesignation NVARCHAR(50)

AS

SELECT EquipmentType.EquipmentTypeID
FROM EquipmentType
WHERE EquipmentTypeDesignation = @EquipmentTypeDesignation

I would like to just do something like this:

DataClasses1DataContext context = new DataClasses1DataContext();

...

var s = context.ReadEquipmentTypeDesignationSP("S9");
s.EquipmentTypeID somethingsomething something

I feel like I'm missing something basic here so thank you for your help.

Answer 1

@EquipmentTypeDesignation NVARCHAR(50)

AS

DECLARE @equipTypeId int

SELECT top 1 @equipTypeId = EquipmentType.EquipmentTypeID
FROM EquipmentType
WHERE EquipmentTypeDesignation = @EquipmentTypeDesignation

RETURN @equipTypeId

in your code

var equipTypeId = context.ReadEquipmentTypeDesignationSP("S9").FirstOrDefault();
