The problem with sending a SqlDataReader back to the caller is that all of the data will be marshaled through the CLR process space on its way back. Since, in this case, the caller generated the data (it came from a table in SQL Server), it would be nice to be able to make the caller return the data on its own without having to send the data back and forth. This is where the ExecuteAndSend() method comes into play. This method accepts a SqlCommand object, which should have both CommandText and Parameters (if necessary) defined. This tells the calling context to execute the command and process the output itself. Letting the caller do the work without sending the data back is quite a bit faster. In some cases, performance can improve by up to 50 percent. Sending all of that data between processes is a lot of

work But this performance improvement comes at a cost; one of the benefits of handling the data within the CLR routine is control Take the following code fragment, for example: commandCommandText = "SELECT * FROM SalesERRORSalesOrderHeader"; try { SqlDataReader reader = commandExecuteReader(); SqlContextPipeSend(reader); } catch (Exception e) { //Do something smart here } This fragment is similar to the fragment discussed in the Using the Send() Method section It requests all of the rows and columns from the table, and then sends the data back to the caller using the Send() method This work is wrapped in a try/catch block the developer, perhaps, can do something to handle any exceptions that occur And indeed, in this code block, an exception will occur the table SalesERRORSalesOrderHeader doesn t exist in the AdventureWorks database.

To do this, we set up a new 4,000-element char array to act as a buffer, and call the StreamReader s ReadBlock method, passing in this array, a starting position of zero (to indicate we want to store the data at the start of the array), and a value of 4,000 to say that we don t want to read more than 4,000 characters in one go This returns an int value containing the number of characters actually read This will return 4,000 if 4,000 or more characters are left in the string, or a value less than 4,000 if there are fewer characters left Once we ve got the character data into the buffer array, we can convert it into a string by calling one of the many overloads of the string constructor.

They can be breached successfully with a little effort and knowledge Vigilance through usage monitoring and effective security policy can limit the effectiveness of attacks, especially because most intrusions will be brute-force based and by definition require repeated access attempts to succeed This is where consultation with your trusty sysadmin will pay dividends Fortunately, within SSIS additional security measures can be implemented at package level to provide extra protection The following package-protection levels can be specified: DontSaveSensitive: Saves the package with all sensitive information, such as passwords, removed EncryptSensitiveWithUserKey: Sensitive data is encrypted using the user key Other users can open the package, but any sensitive data will be cleared Only the user who created and saved the package (and therefore encrypted it using their user key) can see the sensitive data EncryptSensitiveWithPassword: Sensitive data is encrypted using the password entered in the PackagePassword property.

This exception will occur in the CLR routine the ExecuteReader() method will fail At that point, the exception will be caught by the catch block But what about the following code fragment, which uses the ExecuteAndSend() method: commandCommandText = "SELECT * FROM SalesERRORSalesOrderHeader"; try { SqlContextPipeExecuteAndSend(command) } catch (Exception e) { //Do something smart here } Remember that the ExecuteAndSend() method tells the caller to handle all output from whatever T-SQL is sent down the pipe This includes exceptions; so in this case the catch block is hit, but by then it s already too late The caller has already received the exception, and catching it in the CLR routine isn t especially useful So which method, Send() or ExecuteAndSend(), is appropriate for the sales cross-tabulation stored procedure Given the simplicity of the example, the ExecuteAndSend() method makes more sense.

This isn t as secure as encrypting with the user key but is more portable EncryptAllWithPassword: This option encrypts the entire package and contents using the PackagePassword value This makes the package portable and moderately secure EncryptAllWithUserKey: The entire package is encrypted using the user key Obviously, this makes the package much less portable, because it is tied to a specific user account It does, however, make it more secure ServerStorage: Security considerations are deferred to SQL Server Care should therefore be taken to ensure SQL Server security is adequately configured! This option is available only if the package is saved to SQL Server instead of the filesystem..
