FIX: The dynamic query statement appears in the query execution plan of an encrypted stored procedure

View products that this article applies to.

SYMPTOMS

When you run an encrypted stored procedure that contains a dynamic query, and you have turned on the SET STATISTICS PROFILE option, the dynamic query statement or statements may appear in the execution plan of the encrypted stored procedure.

Note In SQL Query Analyzer, turn on the Show Execution Plan option on the Query menu to view the execution plan that the encrypted stored procedure generates.

WORKAROUND

To work around this problem, include the SET SHOWPLAN_ALL ON Transact-SQL statement or the SET SHOWPLAN_TEXT ON Transact-SQL statement when you run an encrypted stored procedure that contains a dynamic query if you have turned on the SET STATISTICS PROFILE option.

For example, use the following Transact-SQL statements to work around this problem.

SET STATISTICS PROFILE ON 
GO

SET SHOWPLAN_ALL ON
GO

--  Run the encrypted stored procedure that contains dynamic SQL statements
EXEC sp_EncryptedStoredProc 
GO

MORE INFORMATION

Steps to reproduce the behavior

Start SQL Query Analyzer, and then connect to SQL Server database.

Run the following Transact-SQL statement in SQL Query Analyzer to create an encrypted stored procedure.

CREATE PROCEDURE sp_EncryptedStoredProc 
WITH ENCRYPTION AS 
BEGIN 
	--  Standard SQL Statement
	SELECT GETDATE()

	--  Dynamic SQL Statement
	EXEC('SELECT @@VERSION')
END

Turn on the SET STATISTICS PROFILE option, and then run the encrypted stored procedure that you created in step 2. To do this, run the following Transact-SQL statements.
SET STATISTICS PROFILE ON GO EXEC sp_EncryptedStoredProc GO
Notice the dynamic Transact-SQL statement that appears under the StmtText column in the Results pane. The StmtText column appears in the clear text format. However, the standard Transact-SQL statement is encrypted.
