DDL Triggers in sql server
 
12:31
ddl trigger example ddl trigger example in sql server ddl triggers can be used to In this video we will discuss DDL Triggers in sql server. In SQL Server there are 4 types of triggers 1. DML Triggers - Data Manipulation Language. Discussed in Parts 43 to 47 of SQL Server Tutorial. 2. DDL Triggers - Data Definition Language 3. CLR triggers - Common Language Runtime 4. Logon triggers What are DDL triggers DDL triggers fire in response to DDL events - CREATE, ALTER, and DROP (Table, Function, Index, Stored Procedure etc...). For the list of all DDL events please visit https://msdn.microsoft.com/en-us/library/bb522542.aspx Certain system stored procedures that perform DDL-like operations can also fire DDL triggers. Example - sp_rename system stored procedure What is the use of DDL triggers If you want to execute some code in response to a specific DDL event To prevent certain changes to your database schema Audit the changes that the users are making to the database structure Syntax for creating DDL trigger CREATE TRIGGER [Trigger_Name] ON [Scope (Server|Database)] FOR [EventType1, EventType2, EventType3, ...], AS BEGIN -- Trigger Body END DDL triggers scope : DDL triggers can be created in a specific database or at the server level. The following trigger will fire in response to CREATE_TABLE DDL event. Use SampleDB Go CREATE TRIGGER trMyFirstTrigger ON Database FOR CREATE_TABLE AS BEGIN Print 'New table created' END To check if the trigger has been created 1. In the Object Explorer window, expand the SampleDB database by clicking on the plus symbol. 2. Expand Programmability folder 3. Expand Database Triggers folder Please note : If you can't find the trigger that you just created, make sure to refresh the Database Triggers folder. When you execute the following code to create the table, the trigger will automatically fire and will print the message - New table created Create Table Test (Id int) The above trigger will be fired only for one DDL event CREATE_TABLE. If you want this trigger to be fired for multiple events, for example when you alter or drop a table, then separate the events using a comma as shown below. ALTER TRIGGER trMyFirstTrigger ON Database FOR CREATE_TABLE, ALTER_TABLE, DROP_TABLE AS BEGIN Print 'A table has just been created, modified or deleted' END Now if you create, alter or drop a table, the trigger will fire automatically and you will get the message - A table has just been created, modified or deleted. The 2 DDL triggers above execute some code in response to DDL events (CREATE_TABLE, ALTER_TABLE, DROP_TABLE). Now let us look at an example of how to prevent users from creating, altering or dropping tables. To do this modify the trigger as shown below. ALTER TRIGGER trMyFirstTrigger ON Database FOR CREATE_TABLE, ALTER_TABLE, DROP_TABLE AS BEGIN Rollback Print 'You cannot create, alter or drop a table' END To be able to create, alter or drop a table, you either have to disable or delete the trigger. To disable trigger 1. Right click on the trigger in object explorer and select "Disable" from the context menu 2. You can also disable the trigger using the following T-SQL command DISABLE TRIGGER trMyFirstTrigger ON DATABASE To enable trigger 1. Right click on the trigger in object explorer and select "Enable" from the context menu 2. You can also enable the trigger using the following T-SQL command ENABLE TRIGGER trMyFirstTrigger ON DATABASE To drop trigger 1. Right click on the trigger in object explorer and select "Delete" from the context menu 2. You can also drop the trigger using the following T-SQL command DROP TRIGGER trMyFirstTrigger ON DATABASE Certain system stored procedures that perform DDL-like operations can also fire DDL triggers. The following trigger will be fired when ever you rename a database object using sp_rename system stored procedure. CREATE TRIGGER trRenameTable ON DATABASE FOR RENAME AS BEGIN Print 'You just renamed something' END The following code changes the name of the TestTable to NewTestTable. When this code is executed, it will fire the trigger trRenameTable sp_rename 'TestTable', 'NewTestTable' The following code changes the name of the Id column in NewTestTable to NewId. When this code is executed, it will fire the trigger trRenameTable sp_rename 'NewTestTable.Id' , 'NewId', 'column' Text version of the video http://csharp-video-tutorials.blogspot.com/2015/09/ddl-triggers-in-sql-server.html Slides http://csharp-video-tutorials.blogspot.com/2015/09/ddl-triggers-in-sql-server_9.html All SQL Server Text Articles http://csharp-video-tutorials.blogspot.com/p/free-sql-server-video-tutorials-for.html All SQL Server Slides http://csharp-video-tutorials.blogspot.com/p/sql-server.html All Dot Net and SQL Server Tutorials in English https://www.youtube.com/user/kudvenkat/playlists?view=1&sort=dd All Dot Net and SQL Server Tutorials in Arabic https://www.youtube.com/c/KudvenkatArabic/playlists

How to find all database constraints with SQL in Oracle.
 
14:49
I have written a small sql code to find out all database constraints. Just be sure you have dba permission, otherwise you might not view all constraints. To see constraints separately for dba and user you can use user or dba instead of all, like user_constraints or dba_constraints, user_cons_columns, dba_cons_columns. I have used all_ to find out everything instead in a single query.

A trigger is a special kind of stored procedure, which is attached with a database table and gets executed automatically in response to certain action on the table like insertion, deletion or updating. You cannot invoke/call it manually, the only way to execute it is to do the required action on the table. There are two types of Triggers: 1. After Triggers (For Triggers) 2.

Oracle 12c PL/SQL Security Features - Lesson 4 of 8 - Roles and PLSQL
 
06:21
Learn how Roles really work with Oracle PL/SQL and why a privilege granted via a role can't be used in PL/SQL. Demonstrations, examples. See all lessons and many more free Oracle Database tutorials at https://www.skillbuilders.com/free-oracle-database-tutorials John Watson: We have the business of roles - roles and PL/SQL. The point here is that roles are invisible to PL/SQL. When you compile your code, only direct privileges are available. When you run your code, only direct privileges are available. This is for definer's rights, I should say. When you run the code, only direct privileges are available to grant to the definer. In effect, the definer's rights code, all roles are disabled within the stored procedure. And certainly roles are disabled when compiling the code. Functionally, it's equivalent to having issued the command SET ROLE NONE. Why is this? Why is it you can't use your privileges? It's perfectly straightforward. It's a technology limitation. Quickly to see what's going on. If I go in and say - let me connect or create a clear schema. I'll create myself, grant dba to jw identified by jw. I've created a user and given him ridiculously high privileges. Connect.... What can you do? You can do pretty much anything. If he wants to delete from scott.emp, he can do it. Let's roll back, because along with his dba role, he has the ability to pretty much anything to use the data. Now we'll create a procedure. If I create a procedure, create delemp as begin, and in there I delete from scott.emp, end, compilation errors. What are they? Show error. At line 2 table of view doesn't exist. That's line 2 delete from scott.emp. I remember way back in version 7, this cause so much confusion before we realized what was going on. It's quite simple that when we are within the code, as the definer or the invoker, because this is definer's rights code, when we are within the definer's rights code block or indeed when we are compiling a definer's rights code block, the roles are disabled and that's why we cannot see it. But why is this and why do I say it's a technology limitation? It's because roles can be enabled and disabled. They can be enabled or disabled. That makes it logically impossible to consider a role when executing a stored procedure because I might have the role enabled while I compile it, but how do I know that it's going to be enabled when I run it? If I grant execute on the code to a third party, he doesn't have the role at all and that he must not even be logged on. So it becomes a logical impossibility because of the way roles are used because roles are enabled or disabled. You can dynamically switch them on and off. It's a logical impossibility to use role within definer's rights program module. Invoker's rights code, however, is very different. That infuses some interesting issues. Invoker's rights code can use any roles that happen to be enabled for the user at the time that he invokes it in exactly the same way that an anonymous PL/SQL can use any enabled roles. In the security point of view, the definer can in effect grab any roles within his code that the invoker happens to have. Dave: [Question], John, pardon. How do you enable or disable a role? John: Right now there's several techniques. I won't spend too much time demonstrating. The easiest technique will be alter - I can set role none. And that will have disabled all my roles. Now if you look at this, I've got nothing. If I try to run my code and query - let's see. Yes. If I try to delete from scott.emp I can't see it. So I'll set role dba and now of course I can. That's the easiest way. In fact, there are much more [05:07 inaudible] ways to switch roles on and off. We can do it with operating system authentication and I can do it with proxy authentication. We have a persistent session through application server as well as a user when we pass that session out to many of the users that can switch roles on and off. That's the persistent session switch identities. Perhaps, best of all, I can create what I call secure application roles well it protect the role with a package and that can contest any number of issues - environment variables, maybe the time, maybe your IP address, perhaps the program you're using and switch roles on and off accordingly. So there are many ways for controlling roles and you should do it. Blindly granting roles and letting them be enabled all the time is not good security. The end result for this, however, you can get some pretty unexpected results within your code. I've tried to run through in our first half hour some of the issues that we see with PL/SQL in release 11g and earlier. After a short break, we'll move on to the 12c features.
