Copying multiple stored procedures to other database - sql-server

Question

In below scenario, I'm trying to import hundreds of procedures into other database.
Solution: SQL Server
Source
SERVER: A
DATABASE: Apple
PROCEDURES: SP1, SP2, SP3 ... SP100
Destination
SERVER: B
DATABASE: Orange
First thing I did was find only non-existing procedures when compared to both databases.
To do so, I used INFORMATION_SCHEMA.ROUTINES from each database and compared in Excel.
After finding a list of procedures to be imported, I wanted to import all procedures at once.
However, if I create procedure in one-lined text, it will be saved one line which has zero visibility.
So, I used sp_helptext to copy by line for each. Then, created little query like below:
create table #proceduretext (runquery varchar(max))
insert into #proceduretext
exec sp_helptext 'SP1'
insert into #proceduretext select 'go'
insert into #proceduretext
exec sp_helptext 'SP2'
insert into #proceduretext select 'go'
insert into #proceduretext
exec sp_helptext 'SP3'
insert into #proceduretext select 'go'
.
.
.
insert into #proceduretext
exec sp_helptext 'SP100'
insert into #proceduretext select 'go'
Then do a select from temp table, paste result, run.
However, above was still insufficient.
Please help with below questions:
Is there a way to use INFORMATION_SCHEMA.ROUTINES for linked servers?
If there is an answer to question 1, how can I loop below query for all missing procedures?
insert into #proceduretext
exec sp_helptext 'SP100'
insert into #proceduretext select 'go'

You can do that with a linked server pretty easily. Here's an example I prepared for you. Run it from within the target database and change the [GREGT580] to whatever your linked server name is.
USE tempdb;
GO
-- Copying from [GREGT580] to local server
SET NOCOUNT ON;
DECLARE #MissingProcedures TABLE
(
MissingProcedureID int IDENTITY(1,1) PRIMARY KEY,
SchemaName sysname,
ProcedureName sysname,
ProcedureDefinition nvarchar(max)
);
INSERT #MissingProcedures
(
SchemaName, ProcedureName, ProcedureDefinition
)
SELECT s.[name], p.[name], sm.definition
FROM [GREGT580].AdventureWorks.sys.procedures AS p
INNER JOIN [GREGT580].AdventureWorks.sys.schemas AS s
ON p.schema_id = s.schema_id
INNER JOIN [GREGT580].AdventureWorks.sys.sql_modules AS sm
ON sm.object_id = p.object_id
WHERE NOT EXISTS (SELECT 1
FROM sys.procedures AS pl
INNER JOIN sys.schemas AS sl
ON sl.schema_id = pl.schema_id
AND sl.[name] = s.[name] COLLATE DATABASE_DEFAULT
AND pl.[name] = p.[name] COLLATE DATABASE_DEFAULT);
DECLARE #SchemaName sysname;
DECLARE #ProcedureName sysname;
DECLARE #ProcedureDefinition nvarchar(max);
DECLARE #Counter int = 1;
WHILE #Counter < (SELECT MAX(MissingProcedureID) FROM #MissingProcedures AS mp)
BEGIN
SELECT #SchemaName = mp.SchemaName,
#ProcedureName = mp.ProcedureName,
#ProcedureDefinition = mp.ProcedureDefinition
FROM #MissingProcedures AS mp
WHERE mp.MissingProcedureID = #Counter;
PRINT #ProcedureDefinition; -- Change to EXEC (#ProcedureDefinition) to create
SET #Counter += 1;
END;
I made the code just print out the procedures, so you could test it. Change the PRINT line to the EXEC option shown when you want to actually created them. (Note that PRINT will truncate what it shows if they are long but EXEC will be fine).
Hope that helps you.
