Question

I have these two tables:

Table: ORDERS
ID - NAME    - DATA
---------------------------------------------
1  - Order 1 - node_checkout_nid";i:141;s:10:
2  - Order 2 - node_checkout_nid";i:142;s:10:

Table: NODES
NID - Description
--------------------
141 - bla bla bla
142 - bla bla bla 2

I need a SQL join query that can join the two tables on NID, keeping in mind the NID is in the “DATA” column.

I need to end with this:

Table: RESULT
ID - NAME    - DATA                             NID - Description
-----------------------------------------------------------------------------------
1  - Order 1 - node_checkout_nid";i:141;s:10: - 141 - bla bla bla
2  - Order 2 - node_checkout_nid";i:142;s:10: - 142 - bla bla bla 2

I wanted to use a “like” join, but I think (if it’s possible) a “contains” join would be better? Any help would be greatly appreciated!

Answer 1

You can use:

SELECT ID, NAME, DATA, NID, Description
  FROM ORDERS INNER JOIN NODES ON DATA LIKE CONCAT('%;i:', NID, ';%')

Anyway it’s a heavy query. It’s not a good idea to have the NID inside the data field as a plain text, better in a different column.
