Finding features with a SQL query
A SQL query can be used to select features based on a combination of attribute values. For example, if you only wanted to find rivers with fluctuating tidal conditions, you could define a SQL query to locate those features.
The Execute SQL check also allows you to run predefined WHERE clauses in a batch on your databases. All features or rows whose parameters match those defined in the SQL query are returned.
Once you have defined the criteria for the check, you can configure the notes and a severity rating. The notes allow you to provide a more specific description for the feature that has been written to the Reviewer table and are copied to the Notes field in the Reviewer table. The severity rating allows you to indicate how important the results from a check are in terms of your quality assurance/quality control processes. The lower the number, the greater the priority the check's results have.
