Ühenduse omadused
If you double-click a connection between two linked fields in the query design, or if you choose Insert - New Relation, the Join Properties dialog appears. These properties will be used in all queries created in the future.

Asjassepuutuvad väljad

Sätted
Tüüp
Specifies the link type of the selected link. Some databases support only a subset of the possible types.
Sisemine ühendus
With the internal join, the results table contains only the records for which the content of the linked fields is the same. In LibreOfficeDev SQL this type of link is created by a corresponding WHERE clause.
Vasakpoolne ühendus
With the left join, the results table contains all fields of the left table and only those fields of the right table for which the content of the linked fields is the same. In LibreOfficeDev SQL this type of link corresponds to the LEFT OUTER JOIN command.
Parempoolne ühendus
With the right join, the results table contains all fields of the right table and only those fields of the left table for which the content of the linked fields is the same. In LibreOfficeDev SQL this type of link corresponds to the RIGHT OUTER JOIN command.
Täielik ühendus
For a full join, the results table contains all fields of the left and right tables. In the SQL of LibreOfficeDev this type of link corresponds to the FULL OUTER JOIN command.
Loomulik
Lisab SQL-lausesse relatsiooni määratleva võtmesõna NATURAL. See relatsioon ühendab kõik veerud, mille nimi on mõlemas tabelis sama. Tulemusena loodav ühendtabel sisaldab igast sama nimega veerupaarist ainult ühte.
