An SQL join clause combines records from two or more tables in a database. It creates a set that can be saved as a table or used as it is. AJOIN
is a means for combining fields from two tables by using values common to each. ANSI-standard SQL specifies five types of JOIN
: INNER
, LEFT OUTER
, RIGHT OUTER
, FULL OUTER
and CROSS
. As a special case, a table can JOIN
to itself in a self-join.
