Schema of an existing table schema-of-an-existing-table
Overview overview
When the application needs to access the data of an existing table, an SQL view, or data from a remote database, create its schema in Adobe Campaign with the following data:
- Name of table: enter the name of the table (with its alias when a dblink is used) with the “sqltable” attribute,
- schema key: reference the reconciliation field(s),
- indexes: used to generate queries,
- The fields and their location in the XML structure: fill in only the fields used in the application,
- links: if there are joins with the other tables of the base.
Implementation implementation
To create the corresponding schema, apply the following stages:
-
Edit the Administration>Configuration>Data schemas node of the Adobe Campaign tree and click New .
-
Select the Access data from an existing table or an SQL view option and click Next .
-
Choose the table or the existing view:
-
Adapt the schema content to suit your needs.
The schema must be populated with the view=“true” attribute on the
<srcSchema>root element in order not to generate a table creation SQL script.
Example :
<srcSchema name="recipient" namespace="cus" view="true">
<element name="recipient" sqltable="dbsrv.recipient">
<key name="email">
<keyfield xpath="@email"/>
</key>
<attribute name="email" type="string" length="80" sqlname="email"/>
</element>
</srcSchema>
