--- title: SQL Drop View Statement --- ## SQL Drop View Statement ### Introduction This guide covers the SQL statement for dropping (deleting) one or more view objects. A View is an object that presents data from one or more tables. Note: before deleting or changing data or objects, remember to have a fresh backup. We will cover: * Using SQL to drop a table * Using the workbench to drop a view We'll be using MySQL for the demontration. Check the manual for this function in other Database Managers. we'll use student table in this tutorial. ```sql select studentID,FullName,sat_score from student; ``` Result : ```text +------------+---------------------+-----------+ | studentID | FullName | sat_score | +------------+---------------------+-----------+ | 1 | Vincent Uvalle | 400 | | 2 | Merle Veres | 800 | | 3 | Donte Emmons | 1000 | | 4 | Demetrius Mccaster | 1200 | | 5 | Tim Goudy | 1400 | | 6 | Stephan Monfort | 1600 | | 7 | Maximo Backstrom | 1800 | | 8 | Dean Pickel | 200 | +------------+---------------------+-----------+ ``` First of all let's create a view. ```sql create view [Failures] AS select studentID, FullName , sat_score from student where sat_score <= 400; ``` Let's see what Failures view consists of ```sql select * from [Failures] ``` Result : ```text +------------+---------------------+-----------+ | studentID | FullName | sat_score | +------------+---------------------+-----------+ | 1 | Vincent Uvalle | 400 | | 8 | Dean Pickel | 200 | +------------+---------------------+-----------+ ``` ### Basic Syntax ```sql drop view [IF EXISTS] view_name [, view_name] ... ``` ### Drop View SQL The if exists portion will "trap" errors, should the view not exist. ```sql drop view if exists [Failures]; ``` Result : ```text Failures table dropped successfully. ``` ### Using the Workbench From the workbench: 1) Right click on the view to drop 2) select drop view from the menu 3) Select either either a) run SQL to review the SQL statement to be executed or b) drop new *As with all of these SQL things there is MUCH MORE to them than what's in this introductory guide. I hope this at least gives you enough to get started. Please see the manual for your database manager and have fun trying different options yourself.*
