Hello all.

I have an SQL command that is somewhere like

"SELECT value FROM table WHERE date = '2017-02-28' AND product_id = 100 LIMIT 1"

There are multiple rows if I don't use limit. But for convenience's sake, I'll say I get the value row to be "A"

Now I put that SQL into a function. And when the function is called, it instead gave out "C", which also fulfilled the date and product_id requirement.

Is there a way I could get "A" no matter what? Hopefully without adding extra WHERE clauses

Thank you.
