How to select columns that are from different tables SQL -


i have table named items , table named orders. orders table need select artists column , orders table need select order_date , ship_date; how can this?

in selecting columns in different tables can use join, left join, or right join connect 2 tables. in doing need 1 same column in both of tables.

join

select table1.colmun_name, table2.column_name table1_name table1  join table2_name table2 on table1.primarykey = table2.table1_primarykey 

for example:

select items.artists, order.order_date, order.ship_date items items left join orders order on item.item_id=order.item_id 

item_id common column in table1 , table2 2 tables can connect each other.

edit: changed table name

as ^ need elaborate question clear want because can put changed table name in query.
