Create dynamic stored procedure for all databases with specific table - sql-server

Question

I would like to add the following stored procedure to all existing databases which contain the table schichten. All my approaches have failed so I'm looking for help here.
This is my approach:
IF object_id('tempdb.dbo.#database') is not null
drop TABLE #database
GO
CREATE TABLE #database(id INT identity primary key, name sysname)
GO
SET NOCOUNT ON
INSERT INTO #database(name)
SELECT name
FROM sys.databases
WHERE source_database_id is null
ORDER BY name
SELECT * FROM #database
DECLARE #id INT, #cnt INT, #sql NVARCHAR(MAX), #currentDb SYSNAME;
SELECT #id = 1, #cnt = max(id) FROM #database
WHILE #id <= #cnt
BEGIN
BEGIN TRY
SELECT #currentDb = name
FROM #database
WHERE id = #id
IF OBJECT_ID(#currentDb+'.dbo.schichten') IS NOT NULL
CREATE PROCEDURE #currentDb.[dbo].[Ausw_Tabelle_Taxi_Pers_Jahr]
#ColumnName nvarchar(MAX),
#Selector nvarchar(MAX),
#Gesamtergebnis nvarchar(MAX)
AS
BEGIN
SET NOCOUNT ON;
DECLARE #sql1 AS NVARCHAR(MAX),
#ASSelector nvarchar(MAX),
#IFPers nvarchar(MAX);
IF #Selector = 'konz'
BEGIN
SET #ASSelector = 'Taxi'
SET #IFPers=''
END
ELSE
BEGIN
SET #ASSelector = 'Personal'
SET #IFPers = '[name] AS Name,'
END
SET #sql1 = N';WITH temp AS (SELECT *
FROM (
SELECT
ISNULL((DATENAME(m,[datum])+ cast(datepart(yyyy,[datum]) as varchar(5))),0) AS MONTHYEAR,
ISNULL(['+ #Selector +'],0) AS '+ #ASSelector +','+ #IFPers +'
ISNULL((ISNULL([umsum],0) +
ISNULL([sonst_0],0) +
ISNULL([sonst_7],0) +
ISNULL([sonst_16],0) +
ISNULL([sonst_z],0) -
ISNULL([ff],0)),0) AS UMSATZSUMME
FROM [dbo].[schichten]
) AS SOURCE
PIVOT (SUM([UMSATZSUMME]) FOR [MONTHYEAR] IN ('+ #ColumnName + N' )) AS UMSAETZE )
SELECT *, '+ #Gesamtergebnis +' AS Gesamtergebnis FROM temp ORDER BY '+ #ASSelector +''
EXEC sp_executesql #sql
END
END TRY
BEGIN CATCH
END CATCH
SET #id = #id + 1;
END
GO
I am hoping that there is someone who can help me.

You have to execute the create procedure separately, so if you wrap it up into a variable and use exec sp_executesql it should work.
IF object_id('tempdb.dbo.#database') is not null
drop TABLE #database
GO
CREATE TABLE #database(id INT identity primary key, name sysname)
GO
SET NOCOUNT ON
INSERT INTO #database(name)
SELECT name
FROM sys.databases
WHERE source_database_id is null
ORDER BY name
SELECT * FROM #database
DECLARE #id INT, #cnt INT, #sql NVARCHAR(MAX), #currentDb SYSNAME;
SELECT #id = 1, #cnt = max(id) FROM #database
WHILE #id <= #cnt
BEGIN
BEGIN TRY
SELECT #currentDb = name
FROM #database
WHERE id = #id
IF OBJECT_ID(#currentDb+'.dbo.schichten') IS NOT NULL
begin
set #sql = 'CREATE PROCEDURE '+#currentDb+'.[dbo].[Ausw_Tabelle_Taxi_Pers_Jahr]
#ColumnName nvarchar(MAX),
#Selector nvarchar(MAX),
#Gesamtergebnis nvarchar(MAX)
AS
BEGIN
SET NOCOUNT ON;
DECLARE #sql1 AS NVARCHAR(MAX),
#ASSelector nvarchar(MAX),
#IFPers nvarchar(MAX);
IF #Selector = ''konz''
BEGIN
SET #ASSelector = ''Taxi''
SET #IFPers=''''
END
ELSE
BEGIN
SET #ASSelector = ''Personal''
SET #IFPers = ''[name] AS Name,''
END
SET #sql1 = N'';WITH temp AS (SELECT *
FROM (
SELECT
ISNULL((DATENAME(m,[datum])+ cast(datepart(yyyy,[datum]) as varchar(5))),0) AS MONTHYEAR,
ISNULL([''+ #Selector +''],0) AS ''+ #ASSelector +'',''+ #IFPers +''
ISNULL((ISNULL([umsum],0) +
ISNULL([sonst_0],0) +
ISNULL([sonst_7],0) +
ISNULL([sonst_16],0) +
ISNULL([sonst_z],0) -
ISNULL([ff],0)),0) AS UMSATZSUMME
FROM [dbo].[schichten]
) AS SOURCE
PIVOT (SUM([UMSATZSUMME]) FOR [MONTHYEAR] IN (''+ #ColumnName + N'' )) AS UMSAETZE )
SELECT *, ''+ #Gesamtergebnis +'' AS Gesamtergebnis FROM temp ORDER BY ''+ #ASSelector +''''
EXEC sp_executesql #sql1
END'
EXEC sp_executesql #sql
END TRY
BEGIN CATCH
END CATCH
SET #id = #id + 1;
END
GO

Assuming this is a one time need as opposed to a nightly maintenance task, you can use a built-in stored procedure, sys.sp_MSforeachdb, to execute a statement in each database. It is safe to use and has been discussed extensively on the web. However, it is an undocumented feature and can be removed without notice by Microsoft so you don't want to depend on it for recurring tasks.
Create and validate your statement in one database, then use this stored procedure to execute it in all of the databases. ? is the placeholder for the database name.
EXEC sys.sp_MSforeachdb #command1 =
'IF OBJECT_ID(''?.dbo.schichten'') IS NOT NULL
AND OBJECT_id(''?.[dbo].[Ausw_Tabelle_Taxi_Pers_Jahr]'') IS NOT NULL
BEGIN
CREATE PROCEDURE ?.[dbo].[Ausw_Tabelle_Taxi_Pers_Jahr]
#ColumnName nvarchar(MAX),
#Selector nvarchar(MAX),
#Gesamtergebnis nvarchar(MAX)
AS
BEGIN
SET NOCOUNT ON;
DECLARE #sql1 AS NVARCHAR(MAX),
#ASSelector nvarchar(MAX),
#IFPers nvarchar(MAX);
IF #Selector = ''konz''
BEGIN
SET #ASSelector = ''Taxi''
SET #IFPers=''''
END
ELSE
BEGIN
SET #ASSelector = ''Personal''
SET #IFPers = ''[name] AS Name,''
END
SET #sql1 = N'';WITH temp AS (SELECT *
FROM (
SELECT
ISNULL((DATENAME(m,[datum])+ cast(datepart(yyyy,[datum]) as varchar(5))),0) AS MONTHYEAR,
ISNULL([''+ #Selector +''],0) AS ''+ #ASSelector +'',''+ #IFPers +''
ISNULL((ISNULL([umsum],0) +
ISNULL([sonst_0],0) +
ISNULL([sonst_7],0) +
ISNULL([sonst_16],0) +
ISNULL([sonst_z],0) -
ISNULL([ff],0)),0) AS UMSATZSUMME
FROM [dbo].[schichten]
) AS SOURCE
PIVOT (SUM([UMSATZSUMME]) FOR [MONTHYEAR] IN (''+ #ColumnName + N'' )) AS UMSAETZE )
SELECT *, ''+ #Gesamtergebnis +'' AS Gesamtergebnis FROM temp ORDER BY ''+ #ASSelector +''''
EXEC sp_executesql #sql1
END
