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.
Classical way of droping multiple objects (tables,procedures,functions,views etc) is writing drop squery for each object separately like given below.
--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 GOBut 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,View3So 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.
