A JOIN clause in SQL combines records from two tables in a relational database and results in a new (temporary) table, also called a "joined table". Structured Query Language () specifies two types of joins: inner and outer.A programmer writes a join  predicate to identify the records for JOINing. If the predicate evaluates true, then the combined record inserts into the joined (temporary) table; otherwise, it does not contribute. Any predicate supported by SQL can become a join-predicate , for example, WHERE-clauses.
