Selecting SQL from two related tables
I have two tables in MySQL customer
andcontacts
each line in customer
can have multiple lines in contacts
and contacts.company
will equalcustomer.sequence
how can I run a query to search both tables and only return results from the table customer
?
for example, if I have this data:
customer:
sequence = 123
company = Company A
sequence = 321
company = Company B
contacts:
company = 123
forename = John
company = 123
forename = Steve
company = 321
forename = Joe
company = 321
forename = Andy
company = 321
forename = John
and I'm looking for Andy - he must return Company A
If I am looking for John, he must return Company A
andCompany B
