I'm looking to display balance when currency_symbol = KSD and user_id = AKWEYR

I have tried a lot of things but nothing works
thank you in advance.

Are you sure there must be records in your table with currency symbol "KSD"? In the example you included, I only see "KST". So that would explain why you don't get any results. But like jreklund says: it's hard to tell without knowing what you already tried.
