SELECT

column_names [,... n] FROM

Table_1 RIGHT JOIN Table_2 ON condition

3. 
   – rasm. Right outer join operatorining Venn diagraamsi orqali ko‘rinishi.
   

4. 
   CROSS JOIN operatori 1 jadvaldagi xar bir element uchun 2 jadvaldagi elementlarni bog`lab chiqadi.
   

SQL CROSS JOIN operatorining sintaksisi quyidagi ko‘rinishda bo‘ladi:

5. 
   SQL FULL OUTER JOIN operatori 1 jadvaldagi xar bir element uchun 2 jadvaldagi elementlarni bog`lab chiqadi. SQL FULL OUTER JOIN operatorining sintaksisi quyidagi ko‘rinishda bo‘ladi:
   

SELECT

column_names [,... n] FROM

Table_1 FULL JOIN Table_2 ON condition

4. 
   – rasm. Full outer join operatorining Venn diagrammasi orqali ko‘rinishi.
   

Ishni bajarish tartibi

1. 
   SQL INNER JOIN operatori
   

So‘rov: SELECT *FROM zavod_xodimlari INNER JOIN kon_xodimlari

ON zavod_xodimlari.FISH=kon_xodimlari.FISH;

Natija:

5. 
   - rasm. Inner join qo‘llanishi natijasi.
   

2. LEFT JOIN operatori

So‘rov: SELECT * FROM zavod_xodimlari LEFT JOIN kon_xodimlari

ON zavod_xodimlari.manzili = kon_xodimlari.manzili;

Natija:

5. 
   - rasm. Left join qo‘llanishi natijasi.
