The records that are explicitly included depend on which side of the connection is used. The left OUTER join contains information from the table on the right side, and it comes from the side.The commonly used usage is to find which records in one table do not match the records in another table .For null values, two null is not equal.

although the result of our previous query was orderly, the new table generated after the run was not sorted by Subprenum and the order was chaotic.It was discovered that this was due to the limitations of SQL Server itself and that if there was a special need to require the data in the staging table to be ordered, the problem could be solved by "creating a clustered Index".
