Rule to open the New Business
Consider as an example that you want to create a business rule to match the age of all customers listed in the age column of a defined table. You want to filter all the age records to identify those that fulfill the specified criterion.
In the Name field, enter a name for this
new SQL business rule.
Avoid using special characters in the item names including:
"~", "!", "`", "#", "^", "&", "*", "\\", "/", "?", ":", ";", "\"", ".", "(", ")", "'", "¥", "'", """, "«", "»", "<", ">".
These characters are all replaced with "_" in the file system and you may end up creating duplicate items.
Set other metadata (purpose, description and author name) in the
corresponding fields and then click Next.
In the Where clause field, enter the
WHERE clause to be used in the analysis.
In this example, the WHERE clause is used to match the records where customer age is greater than 18.
Click Finish to close the New Business Rule wizard.
A sub-folder for this new SQL business rule is displayed under the Rules folder in the DQ Repository tree view. The SQL business rule editor opens with the defined metadata.Note: In the SQL business rule editor, you can modify the WHERE clause or add a new one directly in the Data quality rule view.
If required, set a value in the Criticality
This will act as an indicator to measure the importance of the SQL business rule.
This value is saved in the database and can be used later in the Talend DQ Portal.For more information about the Portal, see the Talend DQ Portal User and Administrator Guide. For more information about installing the Portal, see the Talend Installation and Upgrade Guide.
