database - SQL JOIN and different types of JOINs -


i have been going through many threads on so , other forums. thought summarize "what sql join?" , "what different types of sql joins?".

better illustration on theory

inner join - records match condition in both tables

left join - records table 1 in conjunction records match condition in table 2

right join - records table 2 in conjunction records table 1 match condition

full outer join - combination of both left , right outer joins matching on clause preserving both tables
