Keep up the good work and keep posting. Why any one use cross join? Data output does not make sense. Thanks for sharing the very useful info about Oracle and please keep updating The purpose of a join is to combine the data across tables.

A join is actually performed by the where clause which combi Monday, 6 August JOINS IN ORACLE-different joins in oracle with examples. A join is actually performed by the where clause which combines the specified rows of tables.

If a join involves in more than two tables then Oracle joins first two tables based on the joins condition and then compares the result with the next table and so on. Assume that we have the following tables. Joining the table itself is called self join. Natural join compares all the common columns. This will gives the cross product. Outer join gives the non-matching records along with matching records. This will display the all matching records and the records which are in left hand side table those that are not in right hand side table.

This will display the all matching records and the records which are in right hand side table those that are not in left hand side table.

This will display the all matching records and the non-matching records from both tables. This will display all the records that have matched. PLEASE CHECK OUT OUR LATEST BLOG on: WHAT IS A PARTITION IN ORACLE. WHAT IS AN INLINE VIEW?
