Type of Joins

Type of Joins

INNER Join – Result will contain matching records from both tables

LEFT Join – Result will contain all records from the “left” table even if the join-condition does not find any matching record in the “right” table

RIGHT Join – Result will contain all records from the “right” table even if the join-condition does not find any matching record in the “left” table

FULL Join – Result will contain all records from both tables, and fill in NULLs for missing matches on either side

CROSS Join – Result will contain returns the cartesian product of the sets of records from the two joined tables (Dangerous with large tables)

Select

Insert
