I am working on a Stored Procedure that has two input parameters that I need to use COLLATE SQL_Latin1_General_CP1_CI_AS so that I can query non-case sensitive results; however, I would also like to allow for a Show All Option with the inputs. I have not found a way for the Collate to work in a case statement. Note: As a work around I will code with 4 different If statements for the different scenarios of choosing a value and/or show all, but would like something cleaner if possible. Current Code below
Declare
@INCo as bCompany,
@MatBeg as bMatl,
@MatEnd as bMatl,
@Catg as bGroup,
@Model as VarChar(20),
@PatternM as VarChar(20),
@SellOn as VarChar(20),
@PatternS as VarChar(20),
@ShowZero as bYN
set @INCo = '1'
set @MatBeg = '0'
set @MatEnd = 'ZZZZZZZZZZ'
set @Catg = '0'
set @Model = '637'
set @SellOn = 'EBAY'
set @ShowZero = 'Y'
begin
set @PatternM = '%' + @Model + '%';
set @PatternS = '%' + @SellOn + '%';
select i.INCo, i.Material, h.Description, h.Category, c.Description as CatgDesc, i.Booked as Quantity, i.PhyLoc, p.Storage,
i.udModelFit as FitsModel, i.udSellPriceNew as LikeNewSellPrice, i.udSellPriceUsed as UsedSellPrice, i.udSellingOn as SellingOn
from INMT i
left outer join HQMT h on i.MatlGroup=h.MatlGroup and i.Material=h.Material
left outer join HQMC c on h.MatlGroup=c.MatlGroup and h.Category=c.Category
left outer join udPhysicalloc p on i.PhyLoc=p.Physicalloc
where i.INCo = (CASE when @INCo <> 0 then @INCo else i.INCo END)
and i.Material >= @MatBeg and i.Material <= @MatEnd
and c.Category = (CASE when @Catg <> 0 then @Catg else c.Category END)
and i.udModelFit COLLATE SQL_Latin1_General_CP1_CI_AS like @PatternM
and i.udSellingOn COLLATE SQL_Latin1_General_CP1_CI_AS like @PatternS
and i.Booked >= (CASE when @ShowZero = 'N' then 1 else 0 END)
END
This code works works great if I only care about having non-case sensitive results for @Model and @SellOn. However, like the other parameters I have, I would like to include something that allows to show all results for that parameter. Something like:
i.udModelFit = (CASE when @Model <> 'ALL' then COLLATE SQL_Latin1_General_CP1_CI_AS like @PatternM else i.udModelFit END)
So as an example I would like to input @Model = 'ALL' and @SellOn = 'eBay' and results would be any Model with Sell On = EBAY (non-case sensitive)
Update: I was able to modify Where to the following and I am getting the desired results now.
where i.INCo = (CASE when @INCo <> 0 then @INCo else i.INCo END)
and i.Material >= @MatBeg and i.Material <= @MatEnd
and c.Category = (CASE when @Catg <> 0 then @Catg else c.Category END)
and (
(@Model IS NULL or i.udModelFit COLLATE SQL_Latin1_General_CP1_CI_AS like @PatternM)
or ((i.udModelFit like '%' or i.udModelFit IS NULL) and @Model = 'ALL')
)
and (
(@SellOn IS NULL or i.udSellingOn COLLATE SQL_Latin1_General_CP1_CI_AS like @PatternS)
or ((i.udSellingOn like '%' or i.udSellingOn IS NULL) and @SellOn = 'ALL')
)
and i.Booked >= (CASE when @ShowZero = 'N' then 1 else 0 END)
