Is it possible in SQL to match a LIKE from a list of records in a subquery?

Question

Using these tables, as a sample:

Table CodeVariations

CODE
-----------
ABC_012
DEF_024
JKLX048

And table RegisteredCodes

CODE       AMOUNT
--------   ------
ABCM012         5
ABCK012        25
JKLM048        16

Is it possible to write a query to retrieve all rows in RegisteredCodes when CODE matches a pattern in any row of the CodeVariations table? That is, any row that matches a LIKE pattern of either 'ABC_012', 'DEF_024' or 'JKLX048'

Result should be

CODE       AMOUNT
--------   ------
ABCM012         5
ABCK012        25

I'm using PostgreSQL, but it would be interesting to know if it's possible to do this in a simple query for either PostgreSQL or any other DB.

Answer 1

Does this do what you need?

select distinct RC.* from RegisteredCodes RC, CodeVariations CV
where RC.CODE LIKE CV.CODE;

Answer 2

Is this you are looking for:

SELCET * FROM RegisteredCodes RC WHERE RC.Code IN (SELECT CODE FROM CodeVariations WHERE CODE LIKE ('ABC%') AND CODE LIKE ('%012')

This will fetch all the record that start with 'ABC' and Ends with '012' and similar for 'DEF" and 'JKL'.
OR

Are you looking for something like this?

Answer 3

In Oracle & PostgreSQL you can you single char wildcards "_" for single chars.

select RC.* from RegisteredCodes RC, CodeVariations CV
where RC.CODE LIKE 'ABC_012';

use Substring

select RC.* from RegisteredCodes RC, CodeVariations CV
where RC.CODE LIKE substring(CV.Code,1,3)||'_'||substring(CV.Code,5) ;

Answer 4

select * from CAT_ITEM where DESCRICAO LIKE '%TUBO%%PVC%%DNR%'

All like list is in a string.
