Question

Consider the two following tables. In bold the field name. Below the field name, the field content:

tableA :
group
ops side west
ops north area
commando alpha
backUp
admin

tableB :
groups
ops
commando

What I would like is to make an inner join like query. I tried the following in phpMyAdmin but it is not working:

SELECT tableA.group
FROM tableA
INNER JOIN tableB
ON tableA.group LIKE "'tableB.groups'%"
GROUP BY tableA.group

The expected result would be to have:

ops side west
ops north area
commando alpha

Hope someone can help. Thank you in advance. Cheers. Marc.

Answer 1

SELECT  DISTINCT tableA.group
FROM    tableB
INNER JOIN
        tableA
ON      tableA.group LIKE CONCAT(tableB.groups, '%')
