Query Manager Syntax

Below is a Query Manager query that I wrote with additional comments. I'm going to be making "use" of this query often as a template and example of how to quickly and easily setup future Query Manager queries. I know some people like to make things more complex and sort of "merge" the declare statements with the SET statements... but I just find that outright confusing. This works for me, and makes sense to me logically. I can understand what this is doing just by looking at it, so this is what I'm going to be doing going forward.

--You can add comments with standard SQL comment markers, though since QueryManager uses the multi-line comment marker in its code,

--It is not recommended that you use that, for the sake of clarity in code. Also, it's WAY easier to edit these in an external editor,

--rather than within the Query Manager editor itself, since the window is so small.

 

--Declare your input variables to be used in your main query

DECLARE @Type NVARCHAR(30);

DECLARE @Make NVARCHAR(30);

DECLARE @Model1 NVARCHAR(50);

DECLARE @Model2 NVARCHAR(50);

DECLARE @Model3 NVARCHAR(50);

DECLARE @Model4 NVARCHAR(50);

DECLARE @Model5 NVARCHAR(50);

 

 

--Set the variables to the user input. Note that the query within the SQL comment markers are a UI element that allows users to pick from a list.

--ALL input variables MUST be "attached" to a database table populated with valid data of the correct type for the Query Manager to work properly.

SET @Type = /* SELECT eq.U_Type FROM dbo.[@EQUIPMENTLOCATION] eq WHERE eq.U_Type = */ '[%0]'

SET @Make = /* SELECT eq.U_Make FROM [dbo].[@EQUIPMENTLOCATION] eq WHERE eq.U_Make = */ '[%1]'

 

--Query Manager fills in the "assistance bubble" with ALL values of the field, no matter what.

--See SCN page http://scn.sap.com/thread/3276362 for more info

SET @Model1 = /* SELECT eq.U_Model FROM [dbo].[@EQUIPMENTLOCATION] eq WHERE eq.U_Model = */ '[%2]'

SET @Model2 = /* SELECT eq.U_Model FROM [dbo].[@EQUIPMENTLOCATION] eq WHERE eq.U_Model = */ '[%3]'

SET @Model3 = /* SELECT eq.U_Model FROM [dbo].[@EQUIPMENTLOCATION] eq WHERE eq.U_Model = */ '[%4]'

SET @Model4 = /* SELECT eq.U_Model FROM [dbo].[@EQUIPMENTLOCATION] eq WHERE eq.U_Model = */ '[%5]'

SET @Model5 = /* SELECT eq.U_Model FROM [dbo].[@EQUIPMENTLOCATION] eq WHERE eq.U_Model = */ '[%6]'

 

 

--Now, setup your main query

SELECT *

FROM [dbo].[@EQUIPMENTLOCATION] eq

WHERE eq.U_Type = @Type

    AND eq.U_Make = @Make

    AND (

        eq.U_Model = @Model1

        OR eq.U_Model = @Model2

        OR eq.U_Model = @Model3

        OR eq.U_Model = @Model4

        OR eq.U_Model = @Model5

        )

Hopefully this helps some other newbie along the way someday as well.
