DSP® Application Development
BOA reserved columns are (required fields are indicated by an *):
- boaStatus*
- AddedOn*
- AddedBy*
- AddedVia*
- ChangedBy*
- ChangedOn*
- ChangedVia*
- LockedOn
- LockedBy
- boaLockType
The required columns above must be added to every table.
When the user clicks the Append Columns icon on the Page toolbar of the Data Sources page’s Vertical View, most of these reserved columns are appended to all of the tables that do not already have them in the database. A Designer can also add these columns manually.
NOTE: This feature is used for local SQL data sources only.
NOTE: LockedOn and LockedBy must be added manually where appropriate. Add these columns for any table where multiple users may be editing the same page at the same time to prevent multiple users from editing the same record at the same time.
With the exception of boaStatus, the appended column should not display on the page so should not be added to the view.
NOTE: If the columns exist on the table, they display when a user hovers the mouse cursor over the row edit pencil icon. This allows the developer to exclude the columns from the view, but still take advantage of them.
NOTE: Reserved columns are only automatically added to tables when the Append Columns icon is clicked on the Data SourcesVertical View. Columns are not automatically appended to tables added after this operation is performed. In other words, if tables are added to the data source later, click the Append Columns icon again to add the reserved columns to the new tables.
NOTE: If the columns exist on the table, they display in the Information pane below the Navigation pane when a user hovers the mouse cursor over a row’s edit pencil icon. This allows the Designer to exclude the columns from the view, but still display the column's values on the page.
