Structured Query Language(SQL) as we all know is the database language by the use of which we can perform certain operations on the existing database and also we can use this language to create a database. SQL uses certain commands like Create, Drop, Insert etc. to carry out the required tasks. These SQL commands are mainly categorized into four categories as discussed below: 1. DDL(Data Definition Language) : DDL or Data Definition Language actually consists of the SQL commands that can be used to define the database schema. It simply deals with descriptions of the database schema and is used to create and modify the structure of database objects in database. Examples of DDL commands:  CREATE – is used to create the database or its objects (like table, index, function, views, store procedure and triggers).  DROP – is used to delete objects from the database.  ALTER-is used to alter the structure of the database.  TRUNCATE–is used to remove all records from a table, including all spaces allocated for the records are removed.  COMMENT –is used to add comments to the data dictionary.  RENAME –is used to rename an object existing in the database. 2. DML(Data Manipulation Language) : The SQL commands that deals with the manipulation of data present in database belong to DML or Data Manipulation Language and this includes most of the SQL statements. Examples of DML:  SELECT – is used to retrieve data from the a database.  INSERT – is used to insert data into a table.  UPDATE – is used to update existing data within a table.  DELETE – is used to delete records from a database table. 3. DCL(Data Control Language) : DCL includes commands such as GRANT and REVOKE which mainly deals with the rights, permissions and other controls of the database system. Examples of DCL commands:  GRANT-gives user’s access privileges to database.  REVOKE-withdraw user’s access privileges given by using the GRANT command. 4. TCL(transaction Control Language) : TCL commands deals with the transaction within the database. Examples of TCL commands:  COMMIT– commits a Transaction.  ROLLBACK– rollbacks a transaction in case of any error occurs.  SAVEPOINT–sets a savepoint within a transaction.  SET TRANSACTION–specify characteristics for the transaction.

Oracle 12c PL/SQL Security New Features - Session 5 of 8 - The New Inherit Privileges Privilege
 
06:47
Learn the Oracle Database 12c Inherit Privileges Privilege. Demonstration and Examples. There's a whole new privilege. The inherit privileges privilege. We indeed inherit any privileges privileged. That's just in privileged of course. Any privileges - system privileges, any privileges is an object privilege or new type objects. We can now assign privileges, grant privileges on users. It limits the owner's inheritance of privileges from the invoker. Oracle Corporation is presumably reasonably happy with the way definer's rights code works and definer's rights code as I demonstrated can be highly dangerous. That hasn't really changed in the current release except is will see with the ability to grant roles to code because in invoker's rights we've got huge differences and that's the inheriting of privileges privilege. If you don't have the inheritance enabled, any attempt to execute invoker's rights code will fail because the definer will not be in able to inherit the rights of the invoker. So I'm going to go straight in to do it and then go through the rest of the slides so we can see the sort of issue. Let me lose 11g and go to 12c. What I shall do is create my low privileged user or drop user dev. I don't think he exists. He doesn't. So I'll create my low privileged user. Grant create session, create procedure, select any table to dev identified by dev. It's the same mechanism I use. The same command I use in 11g. I'm creating a developer with a bare minimum that he needs to do his job, which is writing code that lets people query the database. Then log on as him, comm dev/dev and create my procedure. I'll create a version of the code, create or replace procedure list_emp, author ID current user. Invoker's rights code. Remember, this gives my low privilege user dev the ability to insert something horrible in his code which shall then be executed with the invoker's rights. We create the procedure. Now connect / as sysdba - I'll be the highest possible person there is - set server output on and run the code. Execute dev.list_emp looking for the CLARKS. I can't do it. Even as user sys, I can't run that because of the lack of this new privilege. I can correct the situation. I can grant inherit privileges on user sys - which of course one would never normally do - to dev. So I'm now giving my low privilege user the ability to inherit the privileges of user sys when we are running invoker's rights code. And having done that, the code now succeeds. That's the general principle. Without this inherit any privileges code all that doesn't have any privileges privilege, all your invoker's rights code is now blocked. It simply won't run until you grant that privilege to your trusted user. So without inheritance the invoker's rights code will fail. This privilege is in fact granted by default in 12.1 when a user is created. I believe this is purely for backward compatibility. So you don't have to worry about all your codes ceasing to function the moment you have to upgrade but there's no guarantee that this situation will remain as we go through 12.2, 12.3. Also in upgrade I haven't had the time to test comprehensively every possible method of upgrade but certainly this simple test I've done so far, the privilege does appear to be being granted and we can see it. If we look at who's been granted this privilege so far Select grantee, table_name, privilege from dba_tab_privs where privilege like inherit and we see that straight out of the box inherit privileges on a number of users have been granted to public. They have been granted to public. So if I create a brand new user, I grant connect to jw identified by jw, we will see that in the current release - there he is - inherit has beeen granted to public. In the current release by default, your code will continue to function and Oracle often does this with their [05:46 inaudible] with powerful new features. By default, it's configured so there's no change and in the next release it all changes. That's happened to a quite a few releases, quite a few new features, and it wouldn't surprise me if by the time we get to say 12.2 and certainly by the time we get to 13 this behavior changes. So plan for it and look at that privilege and see who it's been granted to and secure your systems. What you need to do is revoke all the inherit privileges grants that's there by default and then grant inherit any privileges very, very sparingly only to a very few trusted users and that should tighten up the danger of definer's inheriting invoker's rights. So a few trusted schemas, create the code in those schemas only and control this very tightly indeed.

Oracle 12c PL/SQL Security Enhancements - Session 2 of 8- Tutorial Agenda
 
04:11
What's in the SkillBuilders Oracle 12c PL/SQL Security New Features tutorial. John Watson: What I want to talk about today is some security issues with 11g PL/SQL and then moving on to Oracle Database 12c. [see how they've been addressed] In general previous releases of the database have had real problems with security particularly with PL/SQL. This does cause a bit of confusion out there when you read third party assessments contrasting Oracle security with say SQL server and so on. Some people will say that Oracle security is rubbish. Other people will say it's fantastic. What causes that paradox? It's because you can secure your database, but you have to do it. Out of the box the database is stuffed full of marvelous facilities - the developer's marvelous facilities for users - but many of them are potentially highly dangerous. So make no mistake. Oracle database can and should be totally secure, but if your DBAs and your programmers don't make it secure it may be wide open to abuse, wide open to hackers. This has always been a problem. With later releases 11 and now 12, the situation is improving. There are more and more things that one can do declaratively, more techniques for tightening up those wonderfully powerful facilities that can be open to abuse. So what I'm going to go through is spend some time with 11g. We have to. We have to understand what some of the problems are that are being addressed. Also, of course, 11g will be available to be useful for several years to come. I'll spend some time in 11g environment looking at some of the major issues in the PL/SQL environment. Then we will move on to 12c and see some of the new facilities and see how they tighten up the security issues that we see with 11g. If possible - I don't know if this will come true or not - I'll maybe have quick look at network access control list I completely re-implemented in 12c and maybe talk a bit about the advanced security option as well as that has changed somewhat too. That's the agenda I intend to follow. Beginning with 11g, we'll go through what are the definer's rights, what are invoker's rights for code, the relationship between roles and PL/SQL. These issues, definer's rights, invoker's rights and roles is potentially very useful but cause a lot of confusion. I remember when I installed PL/SQL, it first came when it was first introduced in version 7 many, many years ago I found this mind bogglingly confusing. Invoker's rights came in a couple of releases later and then died. That added to the confusion because invoker's rights attempted to fix the problem caused by definer's rights. Roles have always been confusing in the PL/SQL 11g environment. We then move on to the 12c techniques. It's a whole new privilege - inherit privileges or inherit any privileges. That tightens up some of the problems with both views and with PL/SQL. They're very nice facility indeed. We can now grow up roles to procedures, so the confusion of roles in PL/SQL, that is not removed, but we can use roles in a much more [03:31 inaudible] fashion with PL/SQL in 12c. Also, closer [03:35 inaudible], that's the concept of the bequeath view. Just as PL/SQL stored procedures they execute definer's rights to invoker's rights with the privileges of the person who owns the PL/SQL or with the privileges of the person who invokes the PL/SQL. It's the same with views. Historically views are always executed with the privileges of the owner. Now, to a certain extent we can have what I might always call an invoker's rights view. Then if we have time, a couple of other things as well.

PL/SQL: Object Type
 
08:31
In this tutorial, you'll learn what is a object type in sql/plsql 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.

SQL: WITH Clause
 
06:11
In this tutorial, you'll learn will learn how to use with clause 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.
