Specifies the join type of the selected join. Some databases support only a subset of the various possible types.

In an inner join, the results table contains only those records for which the content of the linked fields is the same. In LibreOffice SQL this type of link is created by a corresponding WHERE clause.

แƒ›แƒแƒ แƒชแƒฎแƒœแƒ”แƒ แƒจแƒ”แƒ”แƒ แƒ—แƒ”แƒ‘แƒ

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 LibreOffice SQL this type of link corresponds to the LEFT OUTER JOIN command.

แƒ›แƒแƒ แƒฏแƒ•แƒ”แƒœแƒ แƒจแƒ”แƒ”แƒ แƒ—แƒ”แƒ‘แƒ

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 LibreOffice SQL this type of link corresponds to the RIGHT OUTER JOIN command.

แƒกแƒ แƒฃแƒšแƒ˜ แƒจแƒ”แƒ”แƒ แƒ—แƒ”แƒ‘แƒ

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

Natural

In a natural join, the keyword NATURAL in 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.
