In an interview, the best method to describe SQL Joins is to discuss its core function of merging data from two or more tables in SQL. All of the tables involved should have at least one common data column for this to work.
It is typically used to retrieve data, update table contents, or perform operations on the database or tables' structure, utilising any database tools with a user interface to do the operations on the database. SQL is applicable to both relational and multidimensional databases.
The difference between an LEFT JOIN and an LEFT OUTER JOIN is minimal. In PL/SQL, both forms of the syntax provide the same result. Some people suggest using outer in an LEFT JOIN clause to make it clear that you're doing an outer join, but this is completely optional.
