SQL statements (Data Manipulation Language)

  Writing SQL Commands: Before knowing what are DML commands have a glance at what are SQL commands and how to write these commands. well, Commands are the SQL statements that are written by following some syntax to extract data from the database mainly and later on perform some other operations to manage or retain the data according to constraint(rules) in the database. SQL statements consist of reserved words and User-defined words. Reserved words have some specific meanings and can be as it is. They must be spelled properly as required and can not be split across lines such as SELECT ,ALTER,UPDATE etc. User-defined words are created by the user (according to the syntax rule) and represent the name of various database objects such as table column Views etc. Although SQL is a free format language the statements can be made more readable by following these steps.

Types of joins in SQL Equi and Non_Equi join

  Types of Joins in SQL: As the starter of SQL when you will apply any query it has some limitation that the resultant table is generated from one table only but there is some situations arise in which we may have to retrieve data from multiple tables and in that case we will use JOIN operation. If we want to generate the joined table (which will be the resultant table) from row pairing then two tables must have columns with the same values. Joining is the process of combining rows from multiple tables. Through joining, we can generate a short-lived table with all accessed columns from multiple tables that are specified in join. So here we will discuss different types of joins in SQL. How can we perform SQL joins: For performing JOIN we can use more than one table name after FROM keyword. These are obviously the name of those tables from which we want to extract data. Both table names should be written by using a separator or comma between them. WHERE Clause is used to specify ...
