A SOQL query pulls certain records and fields into Apex Code. This post explains a SOQL query that includes Contacts and their related Opportunities from the Year End Tax Receipt app, but I aim to help you understand SOQL in general.
For those of you that want to modify the Year End Tax Receipt for your specific donors:
- Follow along with this post to modify which records will be displayed in the table of gifts last year. We’ll look at an example of only included gifts marked tax deductible.
- Look at the original post to learn how to modify which columns appear in the gift table.
Understand the SOQL
Here’s my SOQL query. This is how I get the records and fields that I’m going to do something with later on in the code.
1 [SELECT LastName, id,Gifts_Last_Year__c,
2 (SELECT Id, CloseDate, Amount FROM Opportunities
3 WHERE CALENDAR_YEAR(CloseDate) =:year
4 AND IsWon = True
5 ORDER BY CloseDate)
6 FROM Contact WHERE npo02__OppAmountLastYear__c > 0
7 WITH SECURITY_ENFORCED]
