what is joins please explain breffly ??
Answer / sravanthi
The Join keyword is used to query data from 2 or more
tables based on the relationship between the columns in the
table.
1. Join : Returns records when there is atleast one matched
record in both the tables.
2. Left Join : Returns all the records of the left table
irrespective match records in both the tables.
3. Right join : It is just reverse case of left join.
4. Full Join : Returns all the records from both the tables
irrespective matching.
