With the element JOIN - 1:1 it is possible to display in the search result the data of a table related to the layer.

If you, e.g. want to display attributes of a specific city district which are not available in the layer itself then it is possible to provide access to additional district specific attributes/fields by configuring a join element.

For a join it is necessary to specify a source table and a target table:

•source table: can be a layer or table that is configured in your WebOffice 10.9 R4 project configuration

•target table: a table configured in WebOffice 10.9 R4 whose attributes should be joined to the source table

 

The JOIN relationship is defined by specifying a key field in both tables, which is used to link them (reference to result field, reference to table field). In this process, one feature of the target table is assigned to each feature of the source table.

 

In the sample below, the cadastral municipality number (KGNR & KG_NR) fields of the involved table and layer are used as key fields.

Properties

Description

Keep all records

Specifies whether all records are retained in the result of the join (Yes, outer join) or not (No, inner join).

icon_comment

Consider the difference between outer and inner joins when having two tables A and B:

•Outer join: All data of table A are displayed, although there is no data in table B. Consequently, all records are retained.

•Inner join: Only values of table A with a matching value in table B will be kept. Some records may be dropped.
