Dropping table in Sql-Server using try-catch block

Question

The code below works and is quite precise, but is it OK to do it like this as against the other 'standard' ways ?

--Drop table if exists
begin try
    drop table #temp
end try

begin catch 
    print 'table does not exist'
end catch

--Create table
create table #temp(a int, b int)

Answer 1

It is better to use

If Object_Id('Tempdb..#temp') Is Not Null
Drop Table #temp
create table #temp

As you intend to create a #temp Table ultimately which does not require try catch to give a error message that #temp Table does not exists

if the create statement was inside the try, it may have some use

Answer 2

Use EXISTS statement, IF tables exists then only drop table. Otherwise create table directly:

BEGIN TRY
  IF Object_Id('Tempdb..#temp') Is Not Null
     DROP Table #temp
  CREATE table #temp
END try
BEGIN CATCH
  PRINT 'table does not exist'
END CATCH
