I have found calculations and accessing variables not intuitive in the RAP environment so these are my notes to help eliminate some pain between tasks.
Basics: SQL = "Structured Query Langauge" Variable = "A container to hold a specific value, this could be an integer, string, etc.."

To get a good report out of Express Maintenance it starts with a good SQL query and how you join the tables to get the data you are looking for.
This example has several queries working together
To do that you first need to know what tables have the data you need.

Inner JOIN
This is the simplest, most understood Join and is the most common. This query will return all of the records in the left table (table A) that have a matching record in the right table (table B). This Join is written as follows:
SELECT <select_list> FROM Table_A A INNER JOIN Table_B B ON A.Key = B.Key
Example: Table A is units and Table B is WorkOrders. The output would be all of the WorkOrders where the Units from Table A matched.
Left JOIN
This query will return all of the records in the left table (table A) regardless if any of those records have a match in the right table (table B). It will also return any matching records from the right table. This Join is written as follows:
SELECT <select_list> FROM Table_A A LEFT JOIN Table_B B ON A.Key = B.Key
Right JOIN
This query will return all of the records in the right table (table B) regardless if any of those records have a match in the left table (table A). It will also return any matching records from the left table. This Join is written as follows:
SELECT <select_list> FROM Table_A A RIGHT JOIN Table_B B ON A.Key = B.Key
Outer JOIN
This Join can also be referred to as a FULL OUTER JOIN or a FULL JOIN. This query will return all of the records from both tables, joining records from the left table (table A) that match records from the right table (table B). This Join is written as follows:
SELECT <select_list> FROM Table_A A FULL OUTER JOIN Table_B B ON A.Key = B.Key
