Inner Joins: Joins are basically used to obtain data from two or more table simultaneously.Not Like: This operator is the opposite of the LIKE operator.Like: This operator is used to select a value by describing a certain pattern for it.Between: This is operator is used when we have a range of values to be selected.This is used to identify that none of the value matches with the values in the list or the subquery. Not In: This operator works the other way round of the IN operator.In: This operator is used with the WHERE clause to find out if the value matches any values in the list or the subquery.Or: This operator is similarly used for the filtering process and for comparison purpose.And: This operator is used for the filtering process with the Boolean logic.Be it sorting in ascending or in descending order. Order By: This clause is used to sort the data according to our requirements.Where: This clause is used to filter out the data according to the conditions provided.From: This clause is used to define the name of the table FROM which data is selected.Select: This clause is used to SELECT the data you require from the respective table.Let’s know about few data manipulation statements: Referential Integrity: To make sure that the foreign key value is always pointing to an existing one, we need Referential Integrity.Index: Just like an index which we have at the back of the book, here we have an index in the database which works as the same.Foreign key: Foreign key is used to establish the relation or the connection between two tables.Since it is a combination of unique + not null. This key value cannot occur twice in the table. Primary key: Primary key is a unique key constraint.Column: Also known as attribute or field.The cols are used to specify the type of data considering that the rows contain the actual data itself. Table: It consists of rows and columns, a matrix with data.Database: The collection of tables with relevant data is known as a Database.In prior to starting with MySQL basics, let us see a few definitions correlated to the database: The XYZ Company may have a database that would require the tables for their employees, their products, the customers and also about the orders. These databases are benefiting us by storing the information categorically. Since we know MySQL is used to store the data in the form of tables. We can avail multiple tables for the end-users with the help of many SQL queries and combined useful information.It also brings forth the Referential Integrity between the rows or columns of various database tables.It also permits us to carry through the database operations on tables, rows, columns and also indexes.It describes the relationship of a database in the form of the tables which are also known as relations.
