I have my query setup as the example the issue is I need information to be returned even if it is not in all three tables. Example: I have table A, B and C. A is student names and addresses. B is contact information for students. C is transportation information for students. All students are in table A and table B. In table C only students that have transportation information are in the table. When I run my query with the two left joins and I do not get all the students, I only get the students that are in all three tables. How do I get all the information for students from table A and table B even if they are not in table C? Thanks!

I was able to solve this by adding IS NULL for table B and C in the WHERE statement.
