SQL Server : Mapping table design

I have 2 tables, Table A and Table B which have the following structure:

Table A:

and

Table B

There is a 1-1 relationship between tables identified by Product_group in Table A and <campaign_month,campaign> in Table B.

For example, ‘ 1808 Product - Group 3a’ = <’201808’,‘group_3a’>.

I am trying to create a mapping table using Tables A and B which should contain 3 columns, namely, <Product_group, campaign_month, campaign>.

Since I am not able to join the two tables, I am looking for other ways of creating the mapping table.

Can someone point me in the right direction?

Is the format of Product_group consistent? If so then you can create a CTE that reformats the columns of Table A to match the formats of Table B. Then you can join the CTE to Table B and obtain the result.

In your example there are two <201808’,‘group_3a> in table_b. Is there a preference to use the first record<111,201808,'group_3a'> and not the second one<115,'201808','group_3a'> for mapping with '1808 Product - Group 3a'

@GeorgeJoseph Every Product_group will have one entry in the mapping table, so both record<111,201808,'group_3a'> and <115,'201808','group_3a'> should be mapped to the same product_group from table A which is '1808 Product - Group 3a'.

@JohnTamburo Yes, as far as I know product group is consistent. However, I do see some entries in Table A like ‘ 1809 Product - Group 1c - Test1’ for which I do not have a corresponding group_1c-Test1 as campaign in Table B.

Consider the following, I am joining the two tables on the basis of whether the string in campaign column(without the _ ) is contained in product_group.

create table tablea(product_group varchar(50));

create table tableb(id_c int,campaign_month int, campaign varchar(50));



insert into tablea values('1808 Product - Group 3a')

insert into tablea values('1808 Product - Group 3b')

insert into tablea values('1808 Product - Group 1c - Test1')

insert into tablea values('1808 Product - Group 3s -1')

insert into tablea values('1808 Product - Group 4d')



insert into tablea values('1808 Product - Group 3a')

insert into tablea values('1808 Product - Group 3b')

insert into tablea values('1808 Product - Group 1c - Test1')

insert into tablea values('1808 Product - Group 3s -1')

insert into tablea values('1808 Product - Group 4d')



   select a.product_group, b.id_c,b.campaign_month,b.campaign

     from tablea a

left join tableb b

      on replace(a.product_group,' -',' ') like '%'+replace(b.campaign,'_',' ')+'%'

Hey @george this is actually helpful. Though, the issue is, that the date is not being used to match the correct product_group. Also, I tried matching a campaign named group_3s_1 to product_group which would be 1809 Product - Group 3s -1. Do you have any suggestions on this?

– Sumedha Nagpal
Nov 20 '18 at 6:36

The idea would be to compare by replace <space><hyphen> with a <space> in the column "product_group" and perform the comparison. I have updated the dbfiddle link and answer.I didnt follow the comment on "date not being used to match"?.
