Single-Table JoinDefs
Although you can use a table as is for a query target, if you define a table as a single-table JoinDef you can:
• Specify that the table is displayed in table-field format rather than simple-field format.
• Set up a Master/Detail or Master/Master relationship between different fields (columns) in the same table.
• Delete columns containing sensitive or unnecessary information from the display by using the ChangeDisplay operation.
• Protect columns from updates but allow queries to display data by using the Rules operation.
• Disable deletion of rows by using the Rules operation.
• Save these formatting features in the database for later execution.
