The SQL Series tutorials are as followsSQL TutorialSQL is the standard computer language for accessing and working with databases.In this tutorial, you'll learn how to access and manipulate data in a data system using SQL,Such databases include:

ROWNUMROWNUM: Represents a row number, which is actually a column, but this column is a pseudo-column that can appear in each table.Example: On the Query Employee table, add ROWNUMSELECT from EMP;From the running, the ROWNUM itself is in the form

1.ROWNUM Use--top-n AnalysisUsing the result set returned by the SELECT statement, you can use pseudo-column rownum if you want to query the top N records by specific criteria.RowNum is a pseudo-column that adds to the result set, which is the
