Question

I am trying to write a complicated stored procedure for the first time. My goal is to get the count with some condition from 2 tables.

Consider Merchant table and Email table.
Email table saves the Email invitations sent by the Merchant. Merchant table has all the Merchant Info along with Email IDs.
My goal is to get the count of EmailID s that are in the Merchant table by checking if the Email invitations sent by Merchant has signed up.

I have tried to make this question clear… Hope i am clear.

Thanks in advance..

Answer 1

Why a stored procedure? It sounds like it can be done in a single SQL query.

Let’s see if I understand your question correctly: Merchants invite other people to become a Merchant as well and you want a list with the number of accepted invitations per merchant?

Something along those lines:

select MerchantName, count(1)
from Merchants, Emails
where Merchants.Id = Emails.Id
and Emails.SignedUp = 'YES!'
group by MerchantName;
