How can I JOIN two tables columns using a wildcard? - sql

Question

I'm using Access 97.
This is what I wanna do:
SELECT *
FROM CodeDIS, ListOfProducts
WHERE CodeDIS.IDNumber LIKE ListOfProducts.IDNumber*;
Sometimes the IDNumber on ListOfProducts has an extra letter indicating some information about the product.
So I have the IDNumber AC244 on CodeDIS but I have AC244P on ListOfProducts.
All I want is to add a wildcard to the end of the condition.
Is this possible?

Answer 1

If the choice is C or P, why not:
SELECT *
FROM CodeDIS, ListOfProducts
WHERE CodeDIS.IDNumber = ListOfProducts.IDNumber & "C"
OR CodeDIS.IDNumber = ListOfProducts.IDNumber & "P"

Answer 2

How about:
SELECT *
FROM CodeDIS, ListOfProducts
WHERE CodeDIS.IDNumber LIKE left(ListOfProducts.IDNumber,5);
or if you like:
SELECT *
FROM CodeDIS a inner join ListOfProducts b on a.IDNumber = left(b.IDNumber,5);

Answer 3

I know this is old, but I have not posted much if ever and thought I would try here.
Why not use a substring function with PATINDEX testing if the last digit is always a character? I'm sure my code is mega-inefficient, but here goes my beginner attempt. I'll bet some could golf my case statement into something smaller.
-- I used the code below
-- It only works if the final digit is lower or uppercase letter of
-- specified language.
DECLARE #CodeDIS TABLE (IdNumber nvarchar(50), BaseRowNum nvarchar(50));
insert into #CodeDIS (IdNumber,BaseRowNum) values ('52352345','1')
insert into #CodeDIS (IdNumber,BaseRowNum) values ('134131','2')
insert into #CodeDIS (IdNumber,BaseRowNum) values ('1343141','3')
insert into #CodeDIS (IdNumber,BaseRowNum) values ('a143321','4')
insert into #CodeDIS (IdNumber,BaseRowNum) values ('c34324','5')
insert into #CodeDIS (IdNumber,BaseRowNum) values ('1343214','6')
insert into #CodeDIS (IdNumber,BaseRowNum) values ('%134324','7')
insert into #CodeDIS (IdNumber,BaseRowNum) values ('a%134324','8')
insert into #CodeDIS (IdNumber,BaseRowNum) values ('1413','9')
;
DECLARE #ListOfProducts TABLE (IdNumber nvarchar(50), UpdateSourceDataColumn nvarchar(50));
insert into #ListOfProducts (IdNumber,UpdateSourceDataColumn) values ('52352345a','11')
insert into #ListOfProducts (IdNumber,UpdateSourceDataColumn) values ('134131','22')
insert into #ListOfProducts (IdNumber,UpdateSourceDataColumn) values ('1343141a','33')
insert into #ListOfProducts (IdNumber,UpdateSourceDataColumn) values ('a143321','44')
insert into #ListOfProducts (IdNumber,UpdateSourceDataColumn) values ('c343245','55')
insert into #ListOfProducts (IdNumber,UpdateSourceDataColumn) values ('1343214Z','66')
insert into #ListOfProducts (IdNumber,UpdateSourceDataColumn) values ('%134324','77')
insert into #ListOfProducts (IdNumber,UpdateSourceDataColumn) values ('a%134324','88')
insert into #ListOfProducts (IdNumber,UpdateSourceDataColumn) values ('1413\','99')
;
SELECT a.*,b.IdNumber as IdNumber2, b.UpdateSourceDataColumn
FROM #CodeDIS a
left join #ListOfProducts b
on a.IdNumber =
case
when PATINDEX(
'[a-zA-Z]',
substring(b.IdNumber,len(b.IdNumber),1)
COLLATE Latin1_General_CS_AS
)=1
then left(b.IdNumber,len(b.IdNumber)-1)
else b.IdNumber
end
;
--IdNumber BaseRowNum IdNumber2 UpdateSourceDataColumn
--52352345 1 52352345a 11
--134131 2 134131 22
--1343141 3 1343141a 33
--a143321 4 a143321 44
--c34324 5 NULL NULL
--1343214 6 1343214Z 66
--%134324 7 %134324 77
--a%134324 8 a%134324 88
--1413 9 NULL NULL
