Advantages of Outer Join
- Increased Data Retrieval: Outer joins can retrieve more data than inner joins since they include non-matching rows in the result set.
- Data Integrity: Outer joins can help maintain data integrity by ensuring that all records in the primary table are returned, even if there are no corresponding records in the secondary table.
- Data Analysis: Outer joins can be useful for data analysis, especially when exploring relationships between data sets and identifying trends and patterns.
Inner Join vs Outer Join
Inner Join and Outer Join are the types of join. The inner join has the work to return the common rows between the two tables, whereas the Outer Join has the work of returning the work of the inner join in addition to the rows which are not matched.
Let’s discuss both of them in detail in this article. Before moving ahead, let’s discuss what is Join in SQL.
In a relational database management system (RDBMS), there are different types of joins that can be used to combine data from two or more tables in a database. The two most common types of joins are Inner Join and Outer Join.
