What is SQL

SQL stands for Structured Query Language. It is used to communicate with a database.SQL statements are used to perform tasks such as update data on a database, or retrieve data from a database. Some common relational database management systems that use SQL are: Oracle, Sybase, Microsoft SQL Server, Access, Ingres, etc.

​

The standard SQL commands such as "Select", "Insert", "Update", "Delete", "Create", and"Drop" can be used to accomplish almost everything that one needs to do with a database.

Types of SQL

Here are five types of widely used SQL queries.

• Data Definition Language (DDL)

• Data Manipulation Language (DML)

• Data Control Language(DCL)

• Transaction Control Language(TCL)

• Data Query Language (DQL)

Data Definition Language(DDL) helps you to define the database structure or schema. Data Manipulation Language (DML) allows you to modify the database instance by inserting, modifying, and deleting its data. It is responsible for performing all types of data modification in a database. DCL (Data Control Language) includes commands like GRANT and REVOKE, which are useful to give "rights & permissions.". Transaction control language or TCL commands deal with the transaction within the database. Data Query Language (DQL) is used to fetch the data from the database.

Let's explore some basic concept in SQL

SQL - Table Fundamentals

A table is a database object that holds user data OR A relational database system contains one or more objects called tables. The data or information for the database are stored in these tables.

​

Each table in SQL associated with the specific data types-

​

• Char(size): This data type is used to store character strings values of fixed length.

• Varchar(size): This data type is used to store variable-length alphanumeric data.

• Date(size): This data is used to represent date and time.

• Number(size): The number data type is used to store numbers(fixed or floating-point).

• Long(size): This data type is used to store variable-length character strings containing up to 2GB.

• Raw/Long raw: The RAW/LONG RAW data tupes is used to store binary data, such as digitized pictures or

• images.

​SQL - Create Table Command

Table creation is done using the create table syntax.

Syntax:
CREATE TABLE tablename (
   columnname1 datatype(size) constraints(if required),
   columnname2 datatype(size) ,
   columnname3 datatype(size) ,
   .
   .columnnameN datatype(size) );

​

Create table command defines each column of the table uniquely. Each column has a minimum of three attribute, a name, data type and size(i.e. column width)

Example: Create table employee

CREATE TABLE employee (
   ID int NOT NULL,
   LastName varchar(255) NOT NULL,
   FirstName varchar(255) NOT NULL,
   Age int,
   Address varchar(100),
   City varchar(50),
   State varchar(50)
);

SQL- Inserting data into a table

The insert statement is used to insert or add a row of data into the table.  Once Table is created the most natural thing to do is load this table with data to be manipulated later. To insert records into a table, enter the key words insert into followed by the table name, followed by an open parenthesis, followed by a list of column names separated by commas, followed by a closing parenthesis, followed by the keyword values, followed by the list of values enclosed in parenthesis.

​

Syntax:
INSERT INTO table_name (column1, column2, column3, ...) VALUES (value1, value2, value3, ...);

OR
INSERT INTO table_name VALUES (value1, value2, value3, ...);

Example:
INSERT INTO employee (ID, lastName, FirstName, Age, Address, City, State) VALUES (101570, ‘Kumar’, ‘Naveen’, 28, ‘XYZ’, ‘Etah’, ‘UP’);

Note: Character statement placed within the insert into statement must be enclosed in single quotes(‘). It has a one-to-one relationship, which means we insert one value in each column at a time.
