  1. Inner Join

  6. Temporal Join

1. Inner Join : This join type returns all the records when there is at least one match in both the tables.

2. Left Outer Join : This join type returns all the records from the left table and the matched rows from the right table.

3. Right Outer Join : This join type returns all the records from the right table and the matched rows from left table.

4. Text Join : This join type is used to get the language specific data from the text tables using theĀ  language column-“SPRAS”. It is only available for Attribute Views.

5. Referential Join : This join type is similar to Inner join type, assuming referential integrity is maintained among the tables.Referential Integrity means, the left table always have a corresponding entry on the right table.
