query returns empty records despite having equal values in all relational tables.

P: 1
My team has made an online restaurant database.
It has following entities:
customer, admin, carrier, kitchen, fooditems and order (associative entity)

Some queries return correct records but some of them return empty records.
For example,
Customer, carrier, order
OR
admin, food items, carrier

Kindly help (we have a demo tomorrow)

You've provided almost no information for us to go on... What is the SQL? What are the columns in the tables? What is some sample data?
