Get to Know How to Decrypt Function in SQL Server
Scenario 1: “Whenever I try to process SQL function, I get an error message that says the text is encrypted and it cannot be processed. This is an annoying condition and I want to get rid of this. I heard from some experts that the SQL objects are encrypted and decrypting them is the only solution to this problem. Please provide me with some effective method to decrypt function in SQL Server.“
Scenario 2: “I was going through some online sites to decrypt function in SQL Server. As I have the decryption key, I tried some method mentioned in a blog. Even after accessing as DAC, I was unable to decrypt SQL function. I got a message saying “Cannot perform alter on ‘dbo.FunctionName because it is an incompatible object type.” Can anyone tell me if there a correct way to decrypt SQL Server version 2012? Is it possible to decrypt using the passcode that I have? Since this is my first attempt to decrypt some SQL objects, please help me out with detailed information.”
Thousands of SQL Server users face the similar situation when they try to decrypt SQL function. Encryption is a commonly used method to safeguard SQL database. But database objects cannot remain encrypted all the time. At some point, the objects have to be decrypted to view and use them. So, we can say that if you are encrypting database function and other objects, you must know how to decrypt function in SQL Server too.
But the main problem is, SQL function decryption is tougher that object encryption. The scripts used for the process is a long one. Therefore, SQL experts suggest using automated tool. That is why, we are going to describe the process to decrypt function in SQL Server with the help of the software.
Decrypt Function in SQL Server is not a Herculean Task Anymore
If you have ever tried to decrypt SQL functions with manual scripts, you must know how complex it is. For the others, we would suggest not to waste your time attempting the approach. Rather go for SQL Decryptor Tool by SysTools that can decrypt all SQL encrypted objects like views, functions, stored procedures, and triggers. The application can process objects located in SQL Server 2019, 2017, 2016, 2014, 2012, 2008, 2005, and 2000. Let us tell you how to run this program to decrypt a particular function named “FnCharLength.”
1. Install the tool on your Computer and proceed with clicking on Start option.
2. On the next screen, select Source Server from the auto-fetched list. If there is no list, type the server name.
3. Choose between Windows and SQL Server as Login Mode. If SQL Server Authentication is chosen, you have to enter Server user name and password. Finally, choose the database name.
4. If you want to view the objects, you can do that in the Preview Page.
5. Expand Functions list and select “FnCharLength” function as this application supports selective data decryption. Users can also select all the functions, if required.
6. Select SQL Server or SQL Server Compatible Scripts as export mode and Select Without Encryption to decrypt.
7. If you have chosen SQL Server Compatible Scripts, the software will prompt you to select the destination location.
8. In case of Live SQL Server, you have to enter target Server name, authentication mode, and target database.
9. Click on Export to transfer the decrypt SQL function to the chosen location.
Conclusion
The knowledge about SQL Server object encryption and decryption both are important for the SQL users. Here we have added the complete guide to decrypt function in SQL Server. By following this simple method, users can get rid of critical script execution technique that often leads to errors.
