Question

I have a table with a column that has concatenated values like this

Table CHILD:

    ChildId       Values
    2           x123,j455
    3           f456,z789 
    4           m333,y567
    5           x123,h888

And I have a master table MASTER that has

Table MASTER:

    MainValues
    x123
    f456
    y567

I need to get a query that’ll select the following data

ChildId MainValues
2       x123
3       f456
4       y567
5       x123

Basically match value from MASTER in child values and return only the master value. How can I do this ? I have tried IN and LIKE clause matching with second table but that doesnt help much since the values are csv. Is there a way to split and match in sqlite ?

EDIT: Table and column names are fictional and intended just to explain this question better

Answer 1

Use a regular expression:

SELECT ChildId,MainValues FROM CHILD INNER JOIN MASTER WHERE ','||[Values]||',' like '%,'||MainValues||',%'

Also, please refrain from using keywords like values for column names…
