Types of Rdbms Point Query Properties
An example Rdbms Point Device Ext used with a SqlServer database is shown below.
The Rdbms Point Query component properties are described in the following list:
- Status
This is a read-only indication of the component's state.
- Fault Cause
This is a read-only indication of the reason for a fault.
- Enabled
This property allows you to enable (true) or disable (false) the execution of the query associated with this component.
- Update Frequency
This value dictates how often the query is automatically executed.
- Last Update
This value indicates the last time that the query was executed.
- Sql
This property provides a field (one of several available) for viewing and editing the query statement. The query provides the criteria for database point discoveries initiated from the Rdbms Point Query Manager View and other views.
NOTE: The SQL field is actually BFormat. This means that additional syntax can be added to the SQL string that will be processed before the SQL is sent to the database.
- Key Column1
It often (but not always) defines the primary key. Use this property together with Key Column2, if necessary, to establish the unique "composite key". See About Key Columns and Primary Keys.
- Key Column2
Use this field if Key Column1 is not enough to establish a unique Key for the imported data. See About Key Columns and Primary Keys.
