UDF disappearing after backup database sql server

Question

Hi. A have a database. After backup I cannot find User Defined Functions. How can I solve it?

Answer 1

My guess is that you had created the function inside a transaction which you had not committed. When the other dev restarted SQL Server, the transaction was rolled back.

Answer 2

Hi @Zokir Sobirjonov ,

Welcome to Microsoft Q&A!
Firstly, you can use the following script to check if the UDF is gone:

SELECT  
     name AS 'Function Name',  
     SCHEMA_NAME(schema_id) AS 'Schema',  
     type_desc AS 'Function Type',   
     create_date AS 'Created Date'  
FROM  
     sys.objects  
WHERE  
     type in ('FN', 'IF', 'FN', 'AF', 'FS', 'FT');  

Yes. As TiborKaraszi said, > That shouldn't happen either.
You can use DBCC CHECKDB to check is the database corrupted.
If there is any corruption, you can restore another good backup. If you don't have a good backup, consider using the DBCC CHECKDB option REPAIR_ALLOW_DATA_LOSS. Of course, in order to prevent data loss, the best option is to restore a new good backup.

Best regards,
Seeya
