在具有相同表名的SQL Server 2016中创建同义词时出错

Question

We have a synonym created for the DB that is year specific ie DST2016. I want to create synonym for the database for the 2017 year ie DST2017, so that all our jobs point to the year 2017 automatically.

When I run the command create synonym ABS for [DST2017].[dbo].[ABS] I get the following error:

There is already an object named 'ABS' in the database.

Any idea how I can get around this?

I'm not sure where you have created the old ones (synonym), but maybe you could do something like this to remove the old ones:

select 'drop  synonym ' + name 
from sys.tables order by name 

Then use this command to create the new ones:

declare @db as varchar(50) = (select db_name())
select 'create synonym ' + name + ' for ' + @db + '.dbo.' + name 
from sys.tables order by name 

You also need to be in a different database that the tables are in, otherwise you will get the error above.
