XOSQL provides a simple query language for databinding objects to user interface controls. The syntax for XOSQL is nearly identical to traditional SQL (Structured Query Language).

The local XOS database (eXtensible Object Store) is queried. This query method is preferred over cloud-based remote queries (such as using SOQL) and results in a performance optimization.

Queried objects and fields must be persisted in the local XOS database to be returned in result sets. See ETL Manager for replicating data from remote data sources.

Example:

<dlog:Repeater id="Repeater1" XOSQL="SELECT TOP 10 FROM Solution WHERE Status='Published' ORDER BY CreatedDate DESC"
NoResultsText="No solutions available">
   <HeaderTemplate>
      <table>
   </HeaderTemplate>
   <ItemTemplate>
      <tr><td> <dlog:Label id="ItemLabel" FieldName="SolutionName" />  </td></tr>
   </ItemTemplate>
   <FooterTemplate>
      </table>
   </FooterTemplate>
</dlog:Repeater>

XOSQL Supported Keywords
