SQL: Delete Vs Truncate Vs Drop
 
08:27
In this tutorial, you'll learn the difference between delete/drop and truncate. PL/SQL (Procedural Language/Structured Query Language) is Oracle Corporation's procedural extension for SQL and the Oracle relational database. PL/SQL is available in Oracle Database (since version 7), TimesTen in-memory database (since version 11.2.1), and IBM DB2 (since version 9.7).[1] Oracle Corporation usually extends PL/SQL functionality with each successive release of the Oracle Database. PL/SQL includes procedural language elements such as conditions and loops. It allows declaration of constants and variables, procedures and functions, types and variables of those types, and triggers. It can handle exceptions (runtime errors). Arrays are supported involving the use of PL/SQL collections. Implementations from version 8 of Oracle Database onwards have included features associated with object-orientation. One can create PL/SQL units such as procedures, functions, packages, types, and triggers, which are stored in the database for reuse by applications that use any of the Oracle Database programmatic interfaces. PL/SQL works analogously to the embedded procedural languages associated with other relational databases. For example, Sybase ASE and Microsoft SQL Server have Transact-SQL, PostgreSQL has PL/pgSQL (which emulates PL/SQL to an extent), and IBM DB2 includes SQL Procedural Language,[2] which conforms to the ISO SQL’s SQL/PSM standard. The designers of PL/SQL modeled its syntax on that of Ada. Both Ada and PL/SQL have Pascal as a common ancestor, and so PL/SQL also resembles Pascal in several aspects. However, the structure of a PL/SQL package does not resemble the basic Object Pascal program structure as implemented by a Borland Delphi or Free Pascal unit. Programmers can define public and private global data-types, constants and static variables in a PL/SQL package.[3] PL/SQL also allows for the definition of classes and instantiating these as objects in PL/SQL code. This resembles usage in object-oriented programming languages like Object Pascal, C++ and Java. PL/SQL refers to a class as an "Abstract Data Type" (ADT) or "User Defined Type" (UDT), and defines it as an Oracle SQL data-type as opposed to a PL/SQL user-defined type, allowing its use in both the Oracle SQL Engine and the Oracle PL/SQL engine. The constructor and methods of an Abstract Data Type are written in PL/SQL. The resulting Abstract Data Type can operate as an object class in PL/SQL. Such objects can also persist as column values in Oracle database tables. PL/SQL is fundamentally distinct from Transact-SQL, despite superficial similarities. Porting code from one to the other usually involves non-trivial work, not only due to the differences in the feature sets of the two languages,[4] but also due to the very significant differences in the way Oracle and SQL Server deal with concurrency and locking. There are software tools available that claim to facilitate porting including Oracle Translation Scratch Editor,[5] CEITON MSSQL/Oracle Compiler [6] and SwisSQL.[7] The StepSqlite product is a PL/SQL compiler for the popular small database SQLite. PL/SQL Program Unit A PL/SQL program unit is one of the following: PL/SQL anonymous block, procedure, function, package specification, package body, trigger, type specification, type body, library. Program units are the PL/SQL source code that is compiled, developed and ultimately executed on the database. The basic unit of a PL/SQL source program is the block, which groups together related declarations and statements. A PL/SQL block is defined by the keywords DECLARE, BEGIN, EXCEPTION, and END. These keywords divide the block into a declarative part, an executable part, and an exception-handling part. The declaration section is optional and may be used to define and initialize constants and variables. If a variable is not initialized then it defaults to NULL value. The optional exception-handling part is used to handle run time errors. Only the executable part is required. A block can have a label. Package Packages are groups of conceptually linked functions, procedures, variables, PL/SQL table and record TYPE statements, constants, cursors etc. The use of packages promotes re-use of code. Packages are composed of the package specification and an optional package body. The specification is the interface to the application; it declares the types, variables, constants, exceptions, cursors, and subprograms available. The body fully defines cursors and subprograms, and so implements the specification. Two advantages of packages are: Modular approach, encapsulation/hiding of business logic, security, performance improvement, re-usability. They support object-oriented programming features like function overloading and encapsulation. Using package variables one can declare session level (scoped) variables, since variables declared in the package specification have a session scope.

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.

How to disconnect all connections on sql server database |kill all connections |disconnect all users
 
03:06
use master ALTER DATABASE YourDatabase SET SINGLE_USER WITH ROLLBACK IMMEDIATE --do you stuff here ALTER DATABASE YourDatabase SET MULTI_USER This video is about killing or disconnect all connections to a database. The easiest way is bringing the database to single user mode and set it back to multiuser mode. This will disconnect all connections form all the users other than current one who is logged to the database. One important aspect here is, do not close the screen once you set the database to single user mode. Because when a database is in single user mode it will allow only a single connection to the database. If you allow dropping your connection and if any other connects to the database you will not be able to connect the database again. So you may have to Stop the SQL server and start again to connect the database. It is also possible to do this using SQL management studio. Right click on the database, go to properties, go to options and move to restrict access option. There you can select the single user mode or multiple user mode. Now The question is why do you need to do this. I mean when, do you want to kill all connections. It is mainly, when you want to have exclusive access to the database. For example a database is not allowing you to restore a backup on this because you cannot grant the exclusive access, then you can bring the database to single user mode; killing all connections; perform your activates and after that set it to the multi user mode. This way you can maintain the exclusive access while you are completing the work.

How to Create an user in Oracle
 
14:49
How to Create an user in Oracle with minimum grants/privileges we need to connect as SYSDBA lets ceate an user test you can see the user is created : But can it connect? lets open a new session we can see it lacks create session priv. so, we grant the create session privilege to user test lets test Its connecting. But is it able to create a table ,lets check. it lacks the ability to create table. SO lets give the privilege. lets test again the create table command. its throwing error regarding no Privilege on users tablespace . But we have given USERS as the default tablespace to test(user). So whats the problem? The problem is there is not quota defined for user test. lets give some quota like "10MB" or UNLIMITED , we will giev 10MB NOw let us test. So we can see that we now have sufficient / minimum privileges for the user test. Hope this will help in understanding the concept behind user creation

Oracle Database 12c Security - Oracle Virtual Private Database (VPD)
 
12:29
Learn how to use Oracle Virtual Private Database (VPD) to secure your data. See all lessons at http://skillbuilders.com/12c-TSDP-Tutorial First, Virtual Private Database. What is it? Answer: It's a declarative technique for enforcing security. Typically, it's based on user application context. That was the first limitation of 8i. Backed with 8i context were session-specific. The context variables were sort in the PGA. That means you simply couldn't use this in a web environment. However, global context, with use of 9i, Virtual Private Database became usable for web applications with connection pooling. But whether you're using it to client server or on a three tier environment, it's declarative technique rather than a programmatic technique. I can go behind the back of the application as a DBA and generate predicates to get appended to all SQLs. Select, insert, update, delete the end users. Issue the SQL and I will generate a predicate that filters the access. It's impossible to bypass. All users will have predicates appended to all their code. It doesn't matter whether they're using SQL Plus, Discoverer, Business Objects, Crystal Reports, eBusiness Suites, whatever they're using, I as DBA can filter their access to roles. The end result, different users see different data sets while running the same code and accessing the same tables, hence, the name Virtual Private Database. Different users will think they're seeing a totally different set of tables, but in fact it's one column database, one set of tables hosting a single application shared by all the users. The mechanism - you can apply VPD to tables, to views, to synonyms, and a declarative technique. Once the technique you write a function that generates the predicate, you associate the function with the table. From then on whenever the user issue SQL against that table the Cost-Based Optimizer rewrites the code. The Cost-Based Optimizer rewrites the user SQL to call the function to generate the predicate. The predicate is then appended to the SQL and it's the modified SQL that is parsed and executed. Let's see how this actually works. I'm working here by the way. This is just a perfectly normal 12.1 database. But what I'm going to demonstrate at this point will in fact work on 11g as well. I'm not going to be using any of the 12c enhancements to VPD for this little demonstration. I'll work in the scott schema. What do we have to do? We write a function to generate the predicate string. Create function. And I'll my function vpdf. The function must conform to a fixed specification. It must take two varchar arguments. One of the arguments is intended to be the schema to which the function will be applied. The other argument is the object within the schema to which the function will be applied. And it must return a varchar2, which is the generated predicate. Let's begin. Within this function you can do just about anything. There are some limitations. It's impossible for the function to query or update the table against which the VPD calls here is going to be applied or we violate the rules of purity that we come across so often with PL/SQL. But apart from that, it can do just about anything - including a number of dreadful side effects can be introduced by writing VPD functions. I'm going to do a very simple one on this one. I'll shall simple return immediately a predicate. What predicate? Ename, which is the ename column from this scott.emp table. Ename should equal sys_context. I'll go to the local context, my user end context, and just extract session user. We can see that John has tested this earlier today and therefore the object already was suggesting and he's just dropping it now and cleaning up the recreate. I hope you realize these really are live demonstrations. I'm not just running scripts. I've created a function. What's that function going to do? It's going to return this value here. Test it. Always test it and see what it's actually going to do. I'll select vpdf. I have to give it a couple of arguments. This one will do for now.

In Part 140, we have implemented "Search Page" using dynamic SQL. Since we have used parameters to build our dynamic SQL statements, it is not prone to SQL Injection attack. This is an example of good dynamic SQL implementation. I have seen lot of software developers, not just the beginners but even experienced developers, buidling their dynamic sql queries by concatenating strings instead of using parameters without realizing that they are opening the doors for SQL Injection. Please check my blog at the following link for code used in the demo. http://csharp-video-tutorials.blogspot.com/2017/04/prevent-sql-injection-with-dynamic-sql.html Since we are concatenating the user input values to build the dynamic sql statement, the end user can very easily inject sql. Imagine, what happens for example, if the user enters the following in the "Firstname" textbox. ' Drop database SalesDB -- With the above SQL injected into the "Firstname" textbox, if you click the "Search" button, the following is the query which is sent to SQL server. This will drop the SalesDB. Select * from Employees where 1 = 1 AND FirstName = '' Drop database SalesDB --' On the other hand, if you use parameters to build your dynamic SQL statements, SQL Injection is not an issue. The following input in the "Firstname" textbox, would not drop the SalesDB database. ' Drop database SalesDB -- The text the user has provided in the "Firstname" textbox is treated as the value for @Firstname parameter. The following is the query that is generated and executed. exec sp_executesql N'Select * from Employees where 1 = 1 AND [email protected]',N'@FirstName nvarchar(26)',@FirstName=N''' Drop database SalesDB --' We don't have this problem of sql injection if we are using stored procedures. "SearchPageWithoutDynamicSQL.aspx" is using the stored procedure "spSearchEmployees" instead of dynamic SQL. The same input in the "Firstname" texbox on this page, would generate the following. Notice, whatever text we typed in the "Firstname" textbox is treated as the value for @FirstName parameter. exec spSearchEmployees @FirstName=N''' Drop database SalesDB --' An important point to keep in mind here is that if you have dynamic SQL in your stored procedure, and you are concatenating strings in that stored procedure to build your dynamic sql statements instead of using parameters, it is still prone to SQL injection. If this is not clear at the moment don't worry, we will discuss an example of this in out next video. So in summary, while dynamic sql provides great flexibility when implementing complicated logic with lot of permutations and combinations, if not properly implemented it may open doors for sql injection. Always use parameters to build dynamic sql statements, instead of concatenating user input values. Another benefit of using parameters to build dynamic sql statements is that it allows cached query plans to be reused, which greatly increases the performance. We will discuss an example of this in our upcoming videos.
