Set Parameter from Schema

This step allows you to set a parameter based on data located in the task’s schema.

 

For example, you may have a data source in the schema where the value changes daily. Instead of the value, you can set a parameter that will hold the update the value whenever it changes.

 

You can use an SQL query to set a parameter based on data located in the task's schema. It is recommended that you use the specific SQL syntax found here. You can examine the expression prior to running it. The result of the query listed is sent to the designated parameter.
