Sol Birleştirme

In a left join, the results table contains all records of the queried fields from the left table and only those records of the queried fields from the right table for which the content of the linked fields is the same. In Collabora Office SQL this type of link corresponds to the LEFT OUTER JOIN command.

Sağ Birleştirme

In a right join, the results table contains all records of the queried fields from the right table and only those records of the queried fields from the left table for which the content of the linked fields is the same. In Collabora Office SQL this type of link corresponds to the RIGHT OUTER JOIN command.

Tam Birleştirme

In a full join, the results table contains all records of the queried fields from the left and right tables. In the SQL of Collabora Office this type of link corresponds to the FULL OUTER JOIN command.

Doğal

In a natural join, the keyword NATURAL is inserted into the SQL statement that defines the relation. The relation joins all columns that have the same column name in both tables. The resulting joined table contains only one column for each pair of equally named columns.
