In this article i am going to explain about how to drop multiple tables,procedures or functions at once. Sometimes we supposed to drop multiple tables. For explanation purpose i have created two tables namely testtable1 and testtable2 and i have created two procedures namely GetTestTable1 and GetTestTable2. Now i will explain the syntax and the query used using this two tables and procedures. Below is the sql script used to create the sample.


--Create table script for Students table

CREATE TABLE Students(Id INT IDENTITY,Name VARCHAR(10))

GO



--Create table script for Subjects table

CREATE TABLE Subjects(Subjectcode INT IDENTITY,SubjectName VARCHAR(10))

GO



--Create procedure script for GetAllStudents procedure

CREATE PROC GetAllStudents

AS

BEGIN

 -- returns all the available students

 SELECT * FROM Students

END

GO



--Create procedure script for GetAllStudents procedure

CREATE PROC GetAllSubjects

AS

BEGIN

 -- returns all the available subjects

 SELECT * FROM Subjects

END

GO


Classical way of droping multiple objects (tables,procedures,functions,views etc) is writing drop squery for each object separately like given below.

DROP TABLE Students
GO
DROP TABLE Subjects
GO
DROP PROC GetAllStudents
GO
DROP PROC GetAllSubjects
GO
But the disadvantage in the above statement is we need to write drop table query for each table or drop proc query to each procedure. Easy way to do this thing is explained below.
--For dropping multiple tables 
DROP TABLE Table1,Table2,Table3
--For dropping multiple procedures 
DROP PROC Procedure1,Procedure2,Procedure3
--For dropping multiple functions 
DROP FUNCTION Function1,Function2,Function3
--For dropping multiple views 
DROP VIEW View1,View2,View3
So it will remove the need for writing drop command for each object. If you have comments or suggestions please share it in the comment. If you have any question then write to us. In the next article i will explain how to drop all the tables,procedures,functions and views in a database using set of sql query.
