Hello group,
I'm using mySql in my app, and this database don't provide functions like INTERSECT or MINUS.
So I need some alternative solution for this. I'm thinkig about array_intersect but unfortunately I don't know anything about arrays. So maybe you will help me with this...
db SELECT give me two groups of numbers:
A -> 43,44,87
B -> 42,43,44
Now, how can I make two arrays, and intersect them -> in the result I shoud be given this: 43,44.
How can I do it ?
