Question

I have the following columns in the database. AgreedStartDate, ActualStartDate. I need to apply the following logic: When the AcualStartDate is within the SAME business week as the AgreedStartDate, then it is ‘inside’ the SLA. If this is not the case then it is ‘outside’ the SLA. If either of the two columns is NULL, then it is ‘incomplete’.

Answer 1

A simple CASE statement? You don’t need to use variables, you can just reference your column names instead. I just used variables for a complete statement.

DECLARE @agreedStartDate DATETIME
DECLARE @actualStartDate DATETIME

SET @agreedStartDate = GETDATE()
SET @actualStartDate = GETDATE()

SELECT
    CASE
        WHEN
            @agreedStartDate IS NULL
            OR
            @actualStartDate IS NULL
        THEN
            'Incomplete'
        WHEN
            DATEPART(wk, @agreedStartDate) = DATEPART(wk, @actualStartDate)
            AND
            DATEPART(yyyy, @agreedStartDate) = DATEPART(yyyy, @actualStartDate)
        THEN
            'Inside'
        ELSE
            'Outside'
    END
