I need to copy a record from a Database DBa
, Table Tbl1
to Database DBx
, Table Tbl1
and get the Scope Identity
inside the same SQL Server 2005
server
I have already checked this:
How to Dynamically change the database using TSQL
but my issue is more complicated.
I do want just to execute something in the DBx
being inside DBa
.
I want to copy a record from one database to one of the other (same) databases in the same server and get the scope_identity back.
The Dynamic SQL is a string. What do we do when we want to copy variables of other datatypes as well?
Example code:
CREATE PROCEDURE dbo.pr_consolidation_copy_group @group_id numeric(10,0),@database_to varchar(100)
AS
DECLARE @group_name char(100),@arrival datetime,@departure datetime,@contact_id char(82)
SELECT @group_name = group_name ,
@arrival = arrival,
@departure = departure,
@contact_id = contact_id
FROM grp
WHERE group_id = @group_id
DECLARE @exec nvarchar(max) = QUOTENAME(@database_to) + N'.sys.sp_executesql',
@sql nvarchar(max) = N'INSERT grp(group_name, arrival, departure, contact_id)
SELECT @group_name, @arrival, @departure, @contact_id;SELECT SCOPE_IDENTITY()'; //How do we handle the variables?
EXEC @exec @sql;
go
Get all variables to string and put CONVERT inside the Dynamic SQL?
I hope I can find another solution because my table is around 300 columns 🙁

Unless I am mistaken, your problem is not as complicated as you think. From what I understand, you want to take some data from your current database, store it in variables and then insert that into another database, returning the id that was inserted. If so, this will do what you need:
You can find more information about outputting a variable in the documentation for sp_executeSql.
