Case statement problem
Posted on 2011-09-28
I have this :
UPDATE Nop_ProductVariant
SET Price = OldPrice + 2.00 + (
CASE
WHEN OldPrice < 5 THEN 5.00 - (OldPrice - ProductCost)
WHEN OldPrice BETWEEN 5 AND 10 THEN 8.00 - (OldPrice - ProductCost)
WHEN OldPrice BETWEEN 10 AND 50 THEN 12.00 - (OldPrice - ProductCost)
END
)
but I need to add another condition :
Instead of :
WHEN OldPrice < 5 THEN 5.00 - (OldPrice - ProductCost)
I need this :
If (OldPrice - ProductCost) < 5.00
THEN 5.00 - (OldPrice - ProductCost)
ELSE OldPrice << need to add that
I need to apply this to the other "WHEN" conditions too.
How do I code this? thanks

Is this what you mean?
UPDATE Nop_ProductVariant
SET Price = OldPrice + 2.00 + (
CASE
WHEN OldPrice < 5 THEN 5.00 - (OldPrice - ProductCost)
WHEN OldPrice BETWEEN 5 AND 10 THEN 8.00 - (OldPrice - ProductCost)
WHEN OldPrice BETWEEN 10 AND 50 THEN 12.00 - (OldPrice - ProductCost)
ELSE OldPrice
END
)

Not 100% sure what you're trying to get. Is this what you're looking for?
CASE
WHEN OldPrice < 5 THEN CASE WHEN (OldPrice = ProductCost) < 5.00 THEN 5.00 - (OldPrice - ProductCost) ELSE OldPrice END
WHEN OldPrice BETWEEN 5 AND 10 THEN 8.00 - (OldPrice - ProductCost)
WHEN OldPrice BETWEEN 10 AND 50 THEN 12.00 - (OldPrice - ProductCost)
END
CASE
WHEN OldPrice < 5 THEN CASE WHEN (OldPrice = ProductCost) < 5.00 THEN 5.00 - (OldPrice - ProductCost) ELSE OldPrice END
WHEN OldPrice BETWEEN 5 AND 10 THEN 8.00 - (OldPrice - ProductCost)
WHEN OldPrice BETWEEN 10 AND 50 THEN 12.00 - (OldPrice - ProductCost)
END
The case has only one ELSE condition , but I believe that what you want is the following to return the OldPrice for the case when none of the conditions are meet:
UPDATE Nop_ProductVariant
SET Price = OldPrice + 2.00 + (
CASE
WHEN OldPrice < 5 THEN 5.00 - (OldPrice - ProductCost)
WHEN OldPrice BETWEEN 5 AND 10 THEN 8.00 - (OldPrice - ProductCost)
WHEN OldPrice BETWEEN 10 AND 50 THEN 12.00 - (OldPrice - ProductCost)
ELSE OldPrice
END
)
UPDATE Nop_ProductVariant
SET Price = OldPrice + 2.00 + (
CASE
WHEN OldPrice < 5 THEN 5.00 - (OldPrice - ProductCost)
WHEN OldPrice BETWEEN 5 AND 10 THEN 8.00 - (OldPrice - ProductCost)
WHEN OldPrice BETWEEN 10 AND 50 THEN 12.00 - (OldPrice - ProductCost)
ELSE OldPrice
END
)
Perhaps you want this?
UPDATE Nop_ProductVariant
SET Price = OldPrice + 2.00 + (
CASE
WHEN (OldPrice - ProductCost) < 5 THEN 5.00 - (OldPrice - ProductCost)
WHEN (OldPrice - ProductCost) BETWEEN 5 AND 10 THEN 8.00 - (OldPrice - ProductCost)
WHEN (OldPrice - ProductCost) BETWEEN 10 AND 50 THEN 12.00 - (OldPrice - ProductCost)
ELSE OldPrice
END
)
Otherwise it seems a straightforward conversion of what you already have...
UPDATE Nop_ProductVariant
SET Price = OldPrice + 2.00 + (
If ((OldPrice - ProductCost) < 5)
THEN
5 - (OldPrice - ProductCost)
ELSE
OldPrice
If (BETWEEN 5 and 10)
THEN
8 - (OldPrice - ProductCost)
ELSE
OldPrice
If (BETWEEN 10 and 20)
THEN
12 - (OldPrice - ProductCost)
ELSE
OldPrice
END
)
UPDATE Nop_ProductVariant
SET Price = OldPrice + 2.00 + (
CASE
WHEN (OldPrice - ProductCost) < 5 THEN 5.00 - (OldPrice - ProductCost)
WHEN (OldPrice - ProductCost) BETWEEN 5 AND 10 THEN 8.00 - (OldPrice - ProductCost)
WHEN (OldPrice - ProductCost) BETWEEN 10 AND 50 THEN 12.00 - (OldPrice - ProductCost)
ELSE OldPrice
END
)

thanks all, . . I meant this :
CASE
WHEN OldPrice < 5 THEN 5.00 - (OldPrice - ProductCost)
NEED THIS INSTEAD :
If (OldPrice - ProductCost) < 5.00
THEN 5.00 - (OldPrice - ProductCost)
ELSE OldPrice
WHEN OldPrice BETWEEN 5 AND 10 THEN 8.00 - (OldPrice - ProductCost)
NEED THIS INSTEAD :
If (OldPrice - ProductCost) < 8.00
THEN 8.00 - (OldPrice - ProductCost)
ELSE OldPrice
WHEN OldPrice BETWEEN 10 AND 50 THEN 12.00 - (OldPrice - ProductCost)
NEED THIS INSTEAD :
If (OldPrice - ProductCost) < 12.00
THEN 12.00 - (OldPrice - ProductCost)
ELSE OldPrice
END
Needed to change all the "WHEN"'s.
nap0leon, does your If statement do this?

Sorry - my IF statement above has several errors in it... I was distracted while writing it up and using ELSE in multiple IFs I don't think it will do what you really want anyway.
I think what you want is a variation of the first one (using WHENS and IFs) Gimme a minute to re-write it.

What you are asking for, I think, is the first of the two I posted which is the same as tim_cs's post:
UPDATE Nop_ProductVariant
SET Price = OldPrice + 2.00 + (
CASE
WHEN ((OldPrice - ProductCost) < 5) THEN 5 - (OldPrice - ProductCost)
WHEN ((OldPrice - ProductCost) < 8) THEN 8 - (OldPrice - ProductCost)
WHEN ((OldPrice - ProductCost) < 12) THEN 12 - (OldPrice - ProductCost)
ELSE OldPrice
END
)
But running it through some test data, I don't think it is doing what you really want for cases where marginal profit is > 12.
Consider the following:
Case for marginal profit < 5 (e.g., 2)
OldPrice = 20
ProductCost = 18
Price = 20 + 2 + (5-2) = 25
Case for marginal profit > 5 but less than 8 (e.g., 6)
OldPrice = 20
ProductCost = 14
Price = 20 + 2 + (8-6) = 24
Case for marginal profit > 8 but less than 12 (e.g., 10)
OldPrice = 20
ProductCost = 10
Price = 20 + 2 + (12-10) = 24
Case for marginal profit > 12 (e.g., 15)
OldPrice = 20
ProductCost = 5
Price = 20 + 2 + (15) = 37
Perhaps instead you want the Price to be simply the OldPrice with no modifications, in which case you would want this:
UPDATE Nop_ProductVariant
SET Price = OldPrice + 2.00 + (
CASE
WHEN ((OldPrice - ProductCost) < 5) THEN OldPrice + 2.00 + 5 - (OldPrice - ProductCost)
WHEN ((OldPrice - ProductCost) < 8) THEN OldPrice + 2.00 + 8 - (OldPrice - ProductCost)
WHEN ((OldPrice - ProductCost) < 12) THEN OldPrice + 2.00 + 12 - (OldPrice - ProductCost)
ELSE OldPrice
END
)
UPDATE Nop_ProductVariant
SET Price = OldPrice + 2.00 + (
CASE
WHEN ((OldPrice - ProductCost) < 5) THEN 5 - (OldPrice - ProductCost)
WHEN ((OldPrice - ProductCost) < 8) THEN 8 - (OldPrice - ProductCost)
WHEN ((OldPrice - ProductCost) < 12) THEN 12 - (OldPrice - ProductCost)
ELSE OldPrice
END
)

WHEN ((OldPrice - ProductCost) < 12) THEN OldPrice + 2.00 + 12 - (OldPrice - ProductCost)
ELSE OldPrice
END
)
ARGH... need an edit button - the last section should read:

WHEN ((OldPrice - ProductCost) < 12) THEN OldPrice + 2.00 + 12 - (OldPrice - ProductCost)
ELSE OldPrice
END
)
