Diagnosing SQL71562 Error When Deploying An Azure SQL Database
When using the “Deploy to Azure Database” option in Microsoft SQL Management Studio to move a database to Azure, you may sometimes come across the following error:
Error SQL71562: Error validating element [dbo].[f]: Synonym: [dbo].[f] has an unresolved reference to object [server].[database_name].[table_name]. External references are not supported when creating a package from this platform.
These type of errors are generated as you cannot setup a linked server in Azure and queries using four-part [server].[database].[schema].[table] references are not supported. I’ve come across a SQL71562 error in the past, but this one was different. Generally, the error details are a lot more helpful and relates to stored procedures or views where a table path contains the database name:
Error SQL71562: Procedure: [dbo].[store_procedure_name] has an unresolved reference to object [database_name].[dbo].[table_name]
Easy enough to resolve. The error I was getting this time threw me as it didn’t point me to any object in the database to where the conflict resides and would require me to look through all possible database objects. This would be easy enough to do manually on a small database, but not a large database consisting of over 50 stored procedures and 30 views. Thankfully, SQL to the rescue...
To search across all stored procedures and views, you can use the LIKE operator to search against the database’s offending system objects based on the details you can gather from the error message:
-- Stored Procedures
SELECT OBJECT_NAME(object_id),
OBJECT_DEFINITION(object_id)
FROM sys.procedures
WHERE OBJECT_DEFINITION(object_id) LIKE '%[database_name]%'
-- Views
SELECT OBJECT_NAME(object_id),
OBJECT_DEFINITION(object_id)
FROM sys.views
WHERE OBJECT_DEFINITION(object_id) LIKE '%[database_name]%'
