Hello,

I have a script that i use to generate the tables and views in two databases.  In the script there is a view that has a join over tables in both databases.

The databases can have different names each time i run the script so this affects the database names in the views.

Is there anyway i can have parameters to a script so i can make it more generic?

Otherwise i must edit the script each time and there is a risk i make a mistake.

You can use NVARCHAR like below:
DECLARE @query NVARCHAR(300);
DECLARE @view1 NVARCHAR(128)
DECLARE @view2 NVARCHAR(128)

set @view1='view1_name'
set @view2='view2_name'

SET @query = N' select * from  ' + @view1 + ' union all  select * from ' + @view2 ;

EXEC sp_executesql @query ;

Open in new window

Create two variables in the top of the script, to store the database names, so you'll only has to change in one place.
Then work only with those variables in that View section.
