sql - Keeping variable scope throughout a script -


i have script has number of select statements connects various linked servers.

i want able run script multiple times in each case servers , databases change , couple of table names change.

i hoping use variables define servers once @ beiginning follows, of course goes out of scope local variables.

declare @table_that_changes varchar(100)  declare @linked_server1 varchar(20) declare @linked_server2 varchar(20) declare @db_onserver1 varchar(100)  declare @db_onserver2 varchar(100) select @linked_server1 = '[server109]',        @linked_server2 = '[server104]',        @db_onserver1 = '[database203434]',        @db_onserver2= '[database416541]',        @table_that_changes = 'losstable_2191'

what's best way store these values equivilant of (for example)

select * @linked_server1.@db_onserver1.dbo.table1

that works throughout script contains lots of select statements?

not want, 1 approach script views on tables remote servers using dynamic sql along lines of (not tested)

declare @table_that_changes varchar(100)  declare @linked_server1 varchar(20) declare @linked_server2 varchar(20) declare @db_onserver1 varchar(100)  declare @db_onserver2 varchar(100) select @linked_server1 = '[server109]',        @linked_server2 = '[server104]',        @db_onserver1 = '[database203434]',        @db_onserver2= '[database416541]',        @table_that_changes = 'losstable_2191'  declare @sql varchar(1000)  set @sql = 'create view linked1.table1 select * ' +            @linked_server2 + '.' + @db_onserver1  + '.table1'  exec( @sql)
