Transparent Data Encryption is a encryption method for encrypting database files at rest. This method is native to the DB engine and is one of the most best methods to encrypt your data files to ensure performance doesn't take a hit. SQL Server and Oracle both support TDE natively on its database engine. Now let … Continue reading Enable TDE (Transparent Data Encryption) for SQL Server 2016
To prevent unauthorized access to your REST modules, APEX provides an easy, declarative way of adding basic authentication. This method utilizes APEX user accounts and RESTful Service Privileges. In order not to expose passwords, you should make sure to enable SSL/HTTPS!
First edit an existing APEX user account, and add the RESTful Services group to that user. In our example we’ll edit the APEX user SCOTT. To do this, navigate to Manage Users and Groups in the workspace where your REST modules are, edit a user, and assign the group in the Group Assignments region:
Next create the RESTful Service Privilege by navigating to RESTful Services in the SQL Workshop. In the Tasks sidebar on the right, click the RESTful Service Privilege link.
Fill out the form and select the modules you want to protect, by shuttling them to the right in Protected Modules.
That’s it! Everything under the…

For those that have never worked with arrays here’s a great way to understand them: If a variable is a piece of paper then the stack of papers is an array. It’s a list of variables or objects, and every programming/scripting language has ways to store these variables or objects linearly so you can access them later via a number of different methods.
So let’s look at how we can create an array of string objects in powershell:
$array = @("test1", "test2", "test3")$array
You can also add an element to the end of an array:
$array = @("test1", "test2", "test3")$array += "test4"$array
You can also add arrays together:
$array = @("test1", "test2", "test3") $array2 = @("test4", "test5") $array = $array + $array2 $array
You can access an element of an array if you know the index number of the element you want. Arrays are indexed by…

Any stored procedure or view or function can be encrypted when stored in the sql server , so a user can not see the code inside even if the user has SYSADMIN role and it is also not recommended to use this encryption option to hide the code because once you use the encryption option Microsoft sql server does not provide the option or the feature to reverse the setting or decrypt the object , so when you use the encryption option , save your code in a separate instance
