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.

We can also say that SQL tables are kind of data structure which are used by database for efficient storage of data. To create a table in our database we use SQL CREATE TABLE command. SQL CREATE TABLE is a type of DATA DEFINITION LANGUAGE also known as DDL. To Create a table in your schema you will require CREATE TABLE system privilege. In our future videos we will see what are system and object privileges and how to grant them to a user. Today for this video we will be using Sample schema HR which already has all the necessary privileges. Ohk Let's see the syntax. CREATE TABLE table name ( column name1 Data-Type(size), column name2 Data-Type(size), ..... ); CREATE TABLE is an oracle reserved word or say an Oracle key word whereas There are 3 different ways of creating a table in Oracle database. Creating a table using Command Line Interface (CLI) in Oracle database For demonstrating how to create table in oracle database using CLI, I'll be using Command prompt. Thats how we create table using command prompt. you can check your table structure by DESCRIBE command for that just write DESC and your table name. Like this Another way of creating a table is by using Graphic user interface (GUI) in Oracle database To demonstrate how to create table using GUI we will use SQL developer. Lets open our SQL developer I am connected to HR schema if you do not know how to create a connection to database using SQL developer please watch my oracle database tutorial 4 that explains database connectivity using SQL developer and command prompt. Link for this video is in the description below. So lets create a table. Creating a table using SQL developer is very easy we do not have to fire any query here. Let's start First of all right click on your connection in which you want to create a table and choose schema browser. This will open a separate schema browser pane or you can expend your connection by clicking this + sign and then right click on table and choose New Table. However I prefer working with schema browser so let's skip to schema browser pane here from the first drop-down list you can choose connection name and in the second drop down list you can choose what database objects you want to work with we want to create a table thus I'll choose table and then click this arrow here and choose option for new table Ok we have created a table wizard first of all give a unique name to your table and add some column as well. For this, click the green plus button. Now we already have a column so give it some name. Also choose a datatype from the list and specify any size you can check this not null column if in case you want to make this a mandatory column you can also specify default value and constraint If you want to make this column a primary key you can click here In my future video i'll show you what are these constraints and different ways of applying them on a column in a table. for this video we will concentrate on create table only so when you are done with all your columns click ok Thats your table You can double click on your table here and can see its structure. Thats it

What is a VIEW in Oracle? An Oracle VIEW, in essence, is a virtual table that does not physically exist. Rather, it is created by a query joining one or more tables. Create VIEW Syntax The syntax for the CREATE VIEW Statement in Oracle/PLSQL is: CREATE VIEW view_name AS SELECT columns FROM tables [WHERE conditions]; view_name The name of the Oracle VIEW that you wish to create. WHERE conditions Optional. The conditions that must be met for the records to be included in the VIEW. Example Here is an example of how to use the Oracle CREATE VIEW: CREATE VIEW sup_orders AS SELECT suppliers.supplier_id, orders.quantity, orders.price FROM suppliers INNER JOIN orders ON suppliers.supplier_id = orders.supplier_id WHERE suppliers.supplier_name = 'Microsoft'; This Oracle CREATE VIEW example would create a virtual table based on the result set of the SELECT statement. You can now query the Oracle VIEW as follows: SELECT * FROM sup_orders; Update VIEW You can modify the definition of an Oracle VIEW without dropping it by using the Oracle CREATE OR REPLACE VIEW Statement. Syntax The syntax for the CREATE OR REPLACE VIEW Statement in Oracle/PLSQL is: CREATE OR REPLACE VIEW view_name AS SELECT columns FROM table WHERE conditions; view_name The name of the Oracle VIEW that you wish to create or replace. Example Here is an example of how you would use the Oracle CREATE OR REPLACE VIEW Statement: CREATE or REPLACE VIEW sup_orders AS SELECT suppliers.supplier_id, orders.quantity, orders.price FROM suppliers INNER JOIN orders ON suppliers.supplier_id = orders.supplier_id WHERE suppliers.supplier_name = 'Apple'; This Oracle CREATE OR REPLACE VIEW example would update the definition of the Oracle VIEW called sup_orders without dropping it. If the Oracle VIEW did not yet exist, the VIEW would merely be created for the first time. Drop VIEW Once an Oracle VIEW has been created, you can drop it with the Oracle DROP VIEW Statement. Syntax The syntax for the DROP VIEW Statement in Oracle/PLSQL is: DROP VIEW view_name; view_name The name of the view that you wish to drop. Example Here is an example of how to use the Oracle DROP VIEW Statement: DROP VIEW sup_orders; This Oracle DROP VIEW example would drop/delete the Oracle VIEW called sup_orders. Frequently Asked Questions Question: Can you update the data in an Oracle VIEW? Answer: A VIEW in Oracle is created by joining one or more tables. When you update record(s) in a VIEW, it updates the records in the underlying tables that make up the View. So, yes, you can update the data in an Oracle VIEW providing you have the proper privileges to the underlying Oracle tables. Question: Does the Oracle View exist if the table is dropped from the database? Answer: Yes, in Oracle, the VIEW continues to exist even after one of the tables (that the Oracle VIEW is based on) is dropped from the database. However, if you try to query the Oracle VIEW after the table has been dropped, you will receive a message indicating that the Oracle VIEW has errors. If you recreate the table (the table that you had dropped), the Oracle VIEW will again be fine.

We cannot use Where clause with TRUNCATE. TRUNCATE removes all rows from a table. Minimal logging in transaction log, so it is performance wise faster. TRUNCATE TABLE removes the data by deallocating the data pages used to store the table data and records only the page deallocations in the transaction log. Identify column is reset to its seed value if table contains any identity column. To use Truncate on a table you need at least ALTER permission on the table. Truncate uses the less transaction space than Delete statement. Truncate cannot be used with indexed views. DELETE DELETE is a DML command. DELETE is executed using a row lock, each row in the table is locked for deletion. We can use where clause with DELETE to filter & delete specific records. The DELETE command is used to remove rows from a table based on WHERE condition. It maintain the log, so it slower than TRUNCATE. The DELETE statement removes rows one at a time and records an entry in the transaction log for each deleted row. Identity of column keep DELETE retain the identity. To use Delete you need DELETE permission on the table. Delete uses the more transaction space than Truncate statement. Delete can be used with indexed views. DROP The DROP command removes a table from the database. All the tables' rows, indexes and privileges will also be removed. No DML triggers will be fired. The operation cannot be rolled back. DROP and TRUNCATE are DDL commands, whereas DELETE is a DML command. DELETE operations can be rolled back (undone), while DROP and TRUNCATE operations cannot be rolled back. #HindiTutorial #DilipSir #askDilipSir #Youtuber #YouTube #you_tuber #Dilip #sir #india #tech #technology #videos #best #tutorial #how #know_how #CSharp #Excel #Word #HTML #CSS #ComputerTips_Tricks #ASP.net #WinFormApp #HowtoFix #VisualStudio #MSPowerPoint #OutLook #SQL #Hindi #Urdu #SocialTech #Facebook #GamePlays #gameplay #game_play #playGame #CallofDuty #CsharpinHindi #HTML5 #Advance_Excel #IA, #RRB, #IBPS, #SSC, #UPPSC, #2nd Grade, #LDC, #POLICE, #COMPUTER, #RAILWAY, #ASSISTANT, #TEACHER

SQL View
 
11:19
SQL is a standard Structured query language for storing, manipulating and retrieving data in databases. View 1) What is a View? A view is a saved SQL query. A view can also be considered as a virtual table. actually retrieves the data from the underlying base tables. vtblEmployee, vtblDepartment Create View vWName as sql query Views can be used to reduce the complexity of the database schema, for non IT users. Views can be used as a mechanism to implement row and column level security. Row Level Security where tblDepartment.DeptName = 'IT' To look at view definition - sp_helptext vWName ; To modify a view - ALTER VIEW statement ; To Drop a view - DROP VIEW vWName. 2) Updateable Views Is it possible to Insert, Update and delete rows, from the underlying tblEmployees table, using view vWEmployeesDataExceptSalary? Yes, SQL server views are updateable. Update vWEmployeesDataExceptSalary Set Name = 'Mikey' Where Id = 2 3) Indexed views when you create an index, on a view, the view gets materialized. This means, the view is now, capable of storing data. In SQL server, we call them Indexed views and in Oracle, Materialized views. vtblProduct , vtblProductSales If you want to create an Index, on a view, the following rules should be followed by the view. For the complete list of all rules, please check MSDN. 1. The view should be created with SchemaBinding option 2. If an Aggregate function in the SELECT LIST, references an expression, and if there is a possibility for that expression to become NULL, then, a replacement value should be specified. In this example, we are using, ISNULL() function, to replace NULL values with ZERO. 3. If GROUP BY is specified, the view select list must contain a COUNT_BIG(*) expression 4. The base tables in the view, should be referenced with 2 part name. In this example, tblProduct and tblProductSales are referenced using dbo.tblProduct and dbo.tblProductSales respectively. Limitation : 1. You cannot pass parameters to a view. Table Valued functions are an excellent replacement for parameterized views. 2.Rules and Defaults cannot be associated with views. 3.The ORDER BY clause is invalid in views unless TOP or FOR XML is also specified. 4.Views cannot be based on temporary tables.

SQL with Oracle 10g XE - Using CREATE TABLE to Build a Table
 
08:17
In this video I use the CREATE TABLE command to create three tables: Books, Publisher, and Author. I use these three tables as sample data. The code I entered in is: CREATE TABLE BOOK ( BOOK_ID VARCHAR(4) PRIMARY KEY, ISBN_10 VARCHAR(10), ISBN_13 VARCHAR(13), TITLE VARCHAR(50), CATEGORY VARCHAR(15), PRICE DECIMAL(6,2), BINDING VARCHAR(1), PUB_DATE VARCHAR(4), AUTHOR_ID SMALLINT, PUBLISHER_ID SMALLINT ); CREATE TABLE PUBLISHER ( PUBLISHER_ID SMALLINT PRIMARY KEY, PUBLISHER_NAME VARCHAR(40) ); CREATE TABLE AUTHOR ( AUTHOR_ID SMALLINT PRIMARY KEY, AUTHOR_LAST VARCHAR(25), AUTHOR_FIRST VARCHAR(20) ); I have to create each table individually in the SQL commands window. This video is part of a series of videos with the purpose of learning the SQL language. For more information visit Lecture Snippets at http://lecturesnippets.com.
