The objective of this SQL Server tutorial is to teach you how to use the OFFSET FETCH clause combination with the ORDER BY clause for pagination.
A table might consist of thousands or even millions of tuples.

Pagination is the process of breaking up a large volume or chunk of information into pages so that ...
The OFFSET FETCH clause combination can only and only be used in a SELECT statement with the ORDER BY clause. It cannot be used otherwise.
The OFFSET clause is the mandatory clause in the combination and follows the ORDER BY clause. The FETCH clause is optional and follows the OFFSET clause. Both the clauses take the number of rows as an argument. The number of rows specified with the OFFSET clause indicates the number of rows that must be skipped in the resultset or the number of row...
The basic syntax of SQL Server OFFSET FETCH clause combination is as follows. In this syntax, 1. expressions – expressions defined here the column(s) or calculation you want to retrieve. If you want to retrieve all the columns simply use * in the place of expressions. 2. tables – one or more than one table from where you want to retrieve data. 3. O...

We will see the different usage scenarios for the OFFSET FETCH clause combination using an example table. Let us consider the case of a music store which has a table called music_genre that stor...
