After you create the object query and specify the conditions, you validate it.
Click Validate to run the query validation. The Validate Query window displays the validation results. If the validation returns an error, review the error message and validate the query again.
After you validate the query, you can save it for later use. For example, if you regularly run an object query on checkin histories, you might want to save the object query so that you can easily run it again.
