Everything about Join (SQL)

SQL clause

A join clause in the Structured Query Language (SQL) combines columns from one or more tables into a new table. The operation corresponds to a join operation in relational algebra. Informally, a join stitches two tables and puts on the same row records with matching fields. There are several variants of JOIN: INNER, LEFT OUTER, RIGHT OUTER, FULL OUTER, CROSS, and others.
