The Sql property is a text editor used to create and display the query statement. Named columns are optional. Unnamed columns are
displayed as “column1, column2, ...” and so on. Key columns are optional. If no key column is specified, the driver uses the
first column as the primary key.
You can execute this query manually and also set a regular interval time for updates using the Update Frequency property.
In a addition to the standard properties (Status, Fault Cause and Enabled), these properties support point queries.
| Property | Value | Description |
|---|---|---|
| Update Frequency | hours, minutes, seconds | Dictates how often the driver automatically executes the query. |
| Last Update | date and time | Indicates the last time the driver executed the query. |
| Sql | text editor | Provides an editor (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: This property is actually BFormat. This means that you can add additional syntax to the SQL string that processes before the
driver sends the query to the database.
