Azure SQL Database SQL71562 error exporting to blob storage
This is an error I’ve seen after migrating to Azure; usually in stored procedures. The error is seen when something has a four-part table reference. For example: [server].[database].[schema].[table]. These are not supported and result in a SQL71562 error.
You may be able to identify the issue by querying your [sys] tables for procedures and views that specifically reference a server or database.
For stored procedures:
SELECT OBJECT_NAME(object_id),
       OBJECT_DEFINITION(object_id)
  FROM sys.procedures
 WHERE OBJECT_DEFINITION(object_id) LIKE '%[DB_NAME]%'

For views:
SELECT OBJECT_NAME(object_id),
       OBJECT_DEFINITION(object_id)
  FROM sys.views
 WHERE OBJECT_DEFINITION(object_id) LIKE '%[DB_NAME]%'

Be sure to replace DB_NAME with the name of one of your databases.
