Creating stored procedure in another database - sql-server

Question

Any idea if it's possible to create a procedure in another database using T-SQL alone, where the name of the database is not known up front and has to be read from a table? Kind of like this example:
Use [MasterDatabase]
Declare #FirstDatabase nvarchar(100)
Select Top 1 #FirstDatabase=[ChildDatabase] From [ChildDatabases]
Declare #SQL nvarchar(4000)
Declare #CRLF nvarchar(10) Set #CRLF=nchar(13)+nchar(10)
Set #SQL =
'Use [+'#Firstdatabase+']'+#CRLF+
'Go'+#CRLF+
'Create Proc [Test] As Select 123'
Exec (#SQL)
See what I'm trying to do? This example fails because Go is actually not a T-SQL command but it something recognised by the query analyser/SQL management studio and produces an error. Remove the Go and it also fails because Create Proc must be the first line of the script. Arrgg!!
The syntax of T-SQL doesn't allow you do things like this:
Create [OtherDatabase].[dbo].[Test]
Which is a shame as it would work a treat! You can do that with Select statements, shame it's inconsistent:
Select * From [OtherDatabase]..[TheTable]

Answer 1

It's a pain, but this is what I do. I took this from an example I found on sqlteam, I think - you might have some quoting issues with the way I did the indiscriminate REPLACE:
DECLARE #sql AS varchar(MAX)
DECLARE #metasql as varchar(MAX)
DECLARE #PrintQuery AS bit
DECLARE #ExecQuery AS bit
SET #PrintQuery = 1
SET #ExecQuery = 0
SET #sql =
'
CREATE PROCEDURE etc.
AS
BEGIN
END
'
SET #metasql = '
USE OtherDatabase
EXEC (''' + REPLACE(#sql, '''', '''''') + ''')
'
IF #PrintQuery = 1
PRINT #metasql
IF #ExecQuery = 1
EXEC (#metasql)

DECLARE #UseAndExecStatment nvarchar(4000),
#SQLString nvarchar(4000)
SET #UseAndExecStatment = 'use ' + #DBName +' exec sp_executesql #SQLString'
SET #SQLString = N'CREATE Procedure [Test] As Select 123'
EXEC sp_executesql #UseAndExecStatment,
N'#SQLString nvarchar(4000)', #SQLString=#SQLString

Answer 3

This is how i have done with Alter Procedure:
DECLARE #metasql as varchar(MAX)
DECLARE #sql AS varchar(MAX)
SET #sql =
'ALTER PROCEDURE [dbo].[GetVersion]
AS
BEGIN
SET NOCOUNT ON;
SELECT TOP(1)[Version] from VersionTable
END'
SET #metasql = '
USE MyProdDb
IF (OBJECT_ID(''GetVersion'') IS NOT NULL OR OBJECT_ID(''GetVersion'', ''P'') IS NOT NULL)
BEGIN
EXEC (''' + REPLACE(#sql, '''', '''''') + ''')
END
'
--PRINT #metasql
EXEC (#metasql)

Answer 4

You could shell out to osql using xp_cmdshell, I suppose.

Answer 5

I dont think this can be done with TSQL.
You could use an SSIS package that looped the names and connected to the servers dynamically which creates the schema (procs ) you need.
This is probably what I would do as it means it is all contained within the package.
Configuration can be kept separate by either using a table or external xml file that contained the list of server/databases to deploy the schema to.

It's not necessary to use EXEC within EXEC.
You can simply use OtherDatabase.sys.sp_executesql
DECLARE #sql AS varchar(MAX) = N'
CREATE PROCEDURE etc.
AS
BEGIN
-- whatever
END
';
PRINT #sql;
EXEC OtherDatabase.sys.sp_executesql #sql;
