First of all. Thanks for good question and trying to confuse uses 🙂 .

If you check msdn, then you will find that every create store procedure and create function, always contains a "GO" statement before the definition.

GO statement will use to create a separate batch. Check below link.

Good try and keep it up. 🙂

Thanks

Nice question Gary!!

This is how Create procedure and function should be written, so that they work:

-- Query #4

USE DBDB;

GO

IF OBJECT_ID('dbo.uspUSP') IS NULL

EXEC ('CREATE PROCEDURE dbo.uspUSP AS SET NOCOUNT OFF')

GO

-- Query #6

USE DBDB;

GO

IF OBJECT_ID('dbo.udfUDF') IS NULL

EXEC ('CREATE FUNCTION dbo.udfUDF(@f int) RETURNS INT AS BEGIN SET @f=1 RETURN @f END ')

GO

did I miss something ???

or there are more than 2 failures ...

select db_id('dbdb')

-- and the second one

select object_id('dbdb')

I don't think it will return the same value for a database.

I dig a little bit on the Object_id for a reference .. and in msdn

http://msdn.microsoft.com/en-us/library/ms190328.aspx

it says

OBJECT_ID Returns the database object identification number of a schema-scoped object.

It would return NULL ..

so the query

USE master;

GO

IF OBJECT_ID('DBDB') IS NULL CREATE DATABASE DBDB

-- it should be IF DB_ID('DBDB') IS NULL CREATE DATABASE DBDB

GO

it would fail, if the database already exist..

EDIT : Okay, in the question , the first query drops the database .. so , it would be fine in this Qotd , but in general.. I think it would be an information while using it in the code..

the explanations says

The CREATE PROCEDURE statement cannot be combined with other Transact-SQL statements in a single batch. The same rule applies to Functions as well, but this is not noted in MSDN.

simplifying it a little bit .. "Create Procedure" can't be inside a BEGIN..END statement..

But Drop Procedure can be

so this will work..

IF OBJECT_ID('dbo.uspUSP') IS not NULL

drop PROCEDURE dbo.uspUSP

GO

so, as lokesh says .. Create a proc using dynamic query 😀 , With IF condition 😛

select db_id('dbdb') -- and the second one select object_id('dbdb')

Nice catch demonfox....I misread and thought both are using DB_ID() 🙂

+1

Drop statement can be also be used 🙂

Lokesh, If you check below links then you will find that before creating store procedure and function there is a "GO" keyword.

GO is used to separate two batches.

Check below two examples. Example 1 generate an error like 'CREATE/ALTER PROCEDURE' must be the first statement in a query batch. But example 2 executes successfully.

---- Example 1

select 1

Create proc Test

AS

select 2

GO

---- Example 2

select 1

GO

Create proc Test

AS

select 2

I hope this will help you. 🙂

Thank you Danny! I know how GO is used as a batch separator 🙂

Actually the confusion was this statement

"every create store procedure and create function, always contains a "GO" statement before the definition."

Reading this, I thought that "GO" is embedded inside create procedure and create function statements automatically........."human craziness, keeps them thinking in all wacky ways :-D"

I am clear now.

Thank! Much Appreciated..

I think , it was the word "Always" accountable for the confusion , if inferred as a general understanding.... GO is actually not required to create a stored procedure .. it is just used as a batch separater.. and hence the error as stated by Vinay..

Good question.

This "create proc (or create function) must be the first thing in the batch" nonsense has long been one of my pet hates. Another is that proc bodies are not delimited, the only thing that can define the end of a proc definition is the end of the batch. These two features are, I believe, the antithesis of sensible language design.
