SQL Server 2008 R2 error in generating the script - sql

Question

I am trying to generated the script of a database on SQL Server 2008 R2
I got this error
Microsoft.SqlServer.Management.Smo.PropertyCannotBeRetrievedException: Property TextHeader is not available for StoredProcedure '[dbo].[p_SYS_GetQDNPassword]'. This property may not exist for this object, or may not be retrievable due to insufficient access rights. The text is encrypted. at Microsoft.SqlServer.Management.SqlScriptPublish.GeneratePublishPage.worker_DoWork(Object sender, DoWorkEventArgs e) at System.ComponentModel.BackgroundWorker.OnDoWork(DoWorkEventArgs e) at System.ComponentModel.BackgroundWorker.WorkerThreadStart(Object argument)
Could you help please?
I don't know what other information you need, but whatever you need, tell me please to give you.

Answer 1

Using the sp_helptext dbo.p_SYS_GetQDNPassword should give you the result:
"The text for object 'YourProcedureName' is encrypted."
This means that stored procedure is created using WITH ENCRYPTION, and SQL Server internally stores the text with the definition of the object in an obfuscated format
The actual definition of an object is stored in system table sys.sysobjvalues which is not directly accessible. By connecting to SQL Server using the Dedicated Administrator Connection (DAC) you can select the imageval column in which the information is stored
Click on Database Engine Query button:
The Connect To Database Engine dialog will pop out. Type the "admin:" prefix before the server name and you'll be connected to DAC
You can find useful info here in this article
http://www.mssqltips.com/sqlservertip/2964/encrypting-and-decrypting-sql-server-stored-procedures-views-and-userdefined-functions/
When you're connected to DAC run the following script from the article:
SET NOCOUNT ON
GO
ALTER PROCEDURE dbo.TestDecryption WITH ENCRYPTION AS
BEGIN
PRINT 'This text is going to be decrypted'
END
GO
DECLARE #encrypted NVARCHAR(MAX)
SET #encrypted = (
SELECT imageval
FROM sys.sysobjvalues
WHERE OBJECT_NAME(objid) = 'TestDecryption' )
DECLARE #encryptedLength INT
SET #encryptedLength = DATALENGTH(#encrypted) / 2
DECLARE #procedureHeader NVARCHAR(MAX)
SET #procedureHeader = N'ALTER PROCEDURE dbo.TestDecryption WITH ENCRYPTION AS '
SET #procedureHeader = #procedureHeader + REPLICATE(N'-',(#encryptedLength
- LEN(#procedureHeader)))
EXEC sp_executesql #procedureHeader
DECLARE #blankEncrypted NVARCHAR(MAX)
SET #blankEncrypted = (
SELECT imageval
FROM sys.sysobjvalues
WHERE OBJECT_NAME(objid) = 'TestDecryption' )
SET #procedureHeader = N'CREATE PROCEDURE dbo.TestDecryption WITH ENCRYPTION AS '
SET #procedureHeader = #procedureHeader + REPLICATE(N'-',(#encryptedLength
- LEN(#procedureHeader)))
DECLARE #cnt SMALLINT
DECLARE #decryptedChar NCHAR(1)
DECLARE #decryptedMessage NVARCHAR(MAX)
SET #decryptedMessage = ''
SET #cnt = 1
WHILE #cnt <> #encryptedLength
BEGIN
SET #decryptedChar =
NCHAR(
UNICODE(SUBSTRING(
#encrypted, #cnt, 1)) ^
UNICODE(SUBSTRING(
#procedureHeader, #cnt, 1)) ^
UNICODE(SUBSTRING(
#blankEncrypted, #cnt, 1))
)
SET #decryptedMessage = #decryptedMessage + #decryptedChar
SET #cnt = #cnt + 1
END
SELECT #decryptedMessage
Of course change the dbo.TestDecryption with your procedure name in the script :)
This script works for me, hope it helps

Answer 2

Use
sp_helptext dbo.p_SYS_GetQDNPassword
and
Try to alter the stored procedure and try to get script
