As illustrated in the video, Oracle Database is a program designed to hold lots of information, or data. There are all kinds of different databases and they all have their uses. Some of the most common ones are MySQL, SQL Server, Sybase, and MongoDB. All of these have different uses. The differences will be easier to understand after you learn more about each kind of database. We did not discuss it much in the video, but if you are wondering what “SQL” means in the title, it stands for structured query language. Structured query language is a human readable computer language that is used to tell databases to do things. We will discuss SQL and Oracle SQL Developer more in future videos.
Databases are better than spreadsheets because they allow multiple users at one time, different levels of access given to users, recovery options and transactions, and it is more protected from hacking and malicious destruction. Programming languages often have very useful functions or methods that can be used to communicate to a database and therefore they are a naturally good option for the back end of programs.
This course will go over all of the major parts of database programming using Oracle SQL. We will be using Oracle 11g, but these videos should still work with other versions, including the most recent 12c.
Q and A
~~~~~~
How much does Oracle cost? The full enterprise edition costs thousands. They have other versions for less and they even have a FREE VERSION! This is known as the XE version (eXpress Edition). That is the one we will be using.
How long does it take to learn SQL? You can learn all of the basics and be an efficient beginner database developer in only about a month of practice. To become an intermediate it can take anywhere from an additional 3 - 6 months with a only a few hours of studying and practicing each day.
How can I learn SQL faster? Take notes and actually mess around with making your own database. Watch these videos until you understand the concepts within them, read articles and books that teach in more depth.

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)

In this video we will discuss writing a SQL query to retrieve all student names that start with letter 'M' without using the LIKE operator.
If the interviewer has not mentioned not to use LIKE operator, we would have written the query using the LIKE operator as shown below.
SELECT * FROM Students WHERE Name LIKE 'M%'
We can use any one of the following 3 SQL Server functions, to achieve exactly the same thing.
CHARINDEX
LEFT
SUBSTRING
The following 3 queries retrieve all student rows whose Name starts with letter 'M'. Notice none of the queries are using the LIKE operator.
SELECT * FROM Students WHERE CHARINDEX('M',Name) = 1
SELECT * FROM Students WHERE LEFT(Name, 1) = 'M'
SELECT * FROM Students WHERE SUBSTRING(Name, 1, 1) = 'M'

SQL Server Query writing strategies is something I have yet to find in any book. When enthusiastic SQL students do this, they experience a revelation. The number of errors drops significantly and the speed at writing complex queries increases immediately. Knowing how to narrow down what we are looking for amongst a vast list of choices helps immensely. Grabbing the right tables first and then the fields second is akin to grabbing the right menu before ordering an item from it. In fact, one student named Tim took this back to his team of SQL developers and they immediately implemented this process.
We are all used to following steps. Most of the time, actions are sequential from top to bottom or left to right. Other times we complete things in phases. The two phases we are going to use in this exercise apply to joining tables. This is easy to implement as we only need remember to organize first and clean up second.
When visiting a new restaurant, we will ask to see the menu, because we want to see all they have to offer. The odds are that we might be interested in half of the items, but only need a few dishes for our group at the table. Looking at the menu is like starting a query with a ‘SELECT *’ statement. Once we have looked at all the fields, we narrow our choice(s) to only the items we want at the time.
Sometimes restaurants have multiple menus. My favorite restaurant has a kids’ menu, an adult menu, a gluten-free menu and a drink menu. These menus were each gathered at our table. Ultimately, in my head, a selection was narrowed to what was needed.
Phase I: Organize. When building a new query from many tables, we often find ourselves wondering, “Where do I start?” First, lay the steps out by identifying which tables contain the essential data. Second, get all the table joins working with a basic ‘SELECT *’ statement. Third, add any basic filtering criteria.
Phase II: Itemize. Once all joins and criteria, such as SELECT, FROM and WHERE are working, we are ready for Phase II. This entails going back and changing our ‘SELECT *’ to an itemized SELECT field list as the final step.
Let’s explore how this two-phase process of Organize and then Itemize can be a big time-saver. We are going to use one of the challenges from the last lab. In Lab 3.2 (Outer Joins), Skill Check 2, we needed to get four fields from two different tables. If we were to list all four desired fields and test one table at time, we will get an error as seen on the right side of the figure below.
In the figure below we write a SELECT statement and part of the FROM clause. When completed, the FROM clause will have two tables, but for now we just want to get the Location table working. By using the ‘SELECT *’ strategy, we remove any possible errors from line 1. From there, we can focus on the more complicated logic used for joining tables together. We can add tables one at a time until everything is working. This is the Organize phase.
NOTE: SELECT * never results in an Error message stating “invalid column name”, however; a SELECT list with itemized field(s) can have this error.
After our query is organized and working, we can go back and itemize the SELECT field list to display only the fields that are necessary. This is done during Phase II (Itemize). The steps for this system are broken down as follows:
Since SELECT is always the first statement in a query, it’s natural to want to write the field names before writing the FROM clause. However; we can save time and trouble by using the ‘*’ until the entire query is working properly. When this is complete, it is very easy to itemize the field list, with the confidence of knowing it will not cause any problems.
Exercise:
Simple membership for a club:
Table1 (id_Member,name_Member, email_member, title, age, company)
Table2 (id_Club,club_name, club_Location, address)
Table3 (id_club, id_member,membership_date)
Q1: Show all member names, email, age, and company from Table1
Q2: Show all club name, location, and address data
Q3: Show member name, club name, club location (hint: Use joins and all 3 tables)

In this tutorial, you'll learn how to use column name starting with digit or underscore.
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.

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.

1. Database fundamentals:
Spend some time on looking what a database is - understand how it works (what is a 'key'? what type of roles exist in a database? what is a table? etc.).
2. Relational databases:
Relational databases are probably the most used database organization. It is fairly easy to comprehend so give it a couple of hours.
3. Data types:
If you know nothing about data types - (If you cannot answer questions like what is a numeric(0,2)? or what is a string?) then you should definitely look into fundamentals about data types. Understanding the data types in SQL Server.
4. Joins methodology:
Understanding how data-sets can be joined across tables and how you extract data.
5. Download SQL Server Express:
Download the free version of MS SQL and create a database on your local computer.

Hey guys,
In this video we learn about some very important initial required commands working with Oracle SQL.It also fix the problem of forgotten password of system user of Oracle 11g .
We learn about three basic command of SQL that is--
create -- It is used for creating the new user in SQL database.
alter -- It is used for changing the password of the user.If you forget the password then it is very important for us.
drop -- It is used for deleting user which is already exists.
We also use grant command to give permission for particular user. This is also useful for starting with Oracle SQL.
This is Abhishek Saxena.This channel is about to solve problem which we faces generally in our daily life.Some times it take a long time to solve it.But we provide a easy solution for these problem.If you like then support us by share and subscribe our channel also press the Bell icon.Thank you for your support.

ORACLE/PLSQL: CASE STATEMENT
The Oracle/PLSQL CASE statement has the functionality of an IF-THEN-ELSE statement. Starting in Oracle 9i, you can use the CASE statement within a SQL statement.
The syntax for the Oracle/PLSQL CASE statement is:
CASE [ expression ]
WHEN condition_1 THEN result_1
WHEN condition_2 THEN result_2
...
WHEN condition_n THEN result_n
ELSE result
END
---------
ARGUMENTS:
expression is optional. It is the value that you are comparing to the list of conditions. (ie: condition_1, condition_2, ... condition_n)
condition_1 to condition_n must all be the same datatype. Conditions are evaluated in the order listed. Once a condition is found to be true, the CASE statement will return the result and not evaluate the conditions any further.
result_1 to result_n must all be the same datatype. This is the value returned once a condition is found to be true.
NOTE:
If no condition is found to be true, then the CASE statement will return the value in the ELSE clause.
If the ELSE clause is omitted and no condition is found to be true, then the CASE statement will return NULL.
You can have up to 255 comparisons in a CASE statement. Each WHEN ... THEN clause is considered 2 comparisons.
Lets apply this function on emp table.
Emp table has 3 dept numbers like 10,20 and 30.
So if I want to display the different dept names based on ID, I have to use IF THEN ELSE condition.
IF deptno=10
THEN
"DEPT1"
ELSE deptno=20
THEN
"DEPT2"
ELSE deptno=30
THEN
"DEPT3"
This entire IF block can be achived using CASE.
CASE deptno
WHEN 10
THEN 'DEPT1'
WHEN 20
THEN 'DEPT2'
WHEN 30
THEN 'DEPT3'
ELSE 'NO DEPT'
END;
Query used in Video:
select empno,ename,deptno,CASE deptno WHEN 10 THEN 'DEPT1' WHEN 20 THEN 'DEPT2' WHEN 30 THEN 'DEPT3' ELSE 'No Dept' END from emp;
