#Sqlite inner join on no match full#
Full outer join (or full join) This will return all rows, as long as there's matching data in one of the tables. Non-Equi Join is also a type of INNER Join in which we need to retrieve data from multiple tables. Right outer join (or right join) This will return rows that have data in the right table (right of the JOIN keyword), even if there's no matching rows in the left table. Left outer join (or left join) This will return rows that have data in the left table (left of the JOIN keyword), even if there's no matching rows in the right table.
These are different in a subtle way Inner join This will only return rows when there is at least one row in both tables that match the join condition. Join Typesĭepending on your requirements, you can do an "inner" join or an "outer" join. You can use multiple joins in the same SQL statement to query data from as many tables as you like. These two columns contain data that is shared across both tables. When you perform a SQL join, you specify one column from each table to join on. You can JOIN with the same table more than once by giving the joined tables an alias, as in the following example: SELECT airline, fltno, fairport, tairport, depart, arrive, fare FROM flights INNER JOIN airports fromport ON (de flights.fairport) INNER JOIN airports toport ON (de flights.tairport) WHERE from. The SQL "join" refers to using the JOIN keyword in a SQL statement in order to query data from two tables. The SQLite INNER JOIN is a join where the values in the join columns are compared using an equals comparison operator.
