How to remove SQL Azure Data Sync objects manually

Question

Having given up on SQL Azure Data Sync for synchronizing data between two SQL Azure databases, how can I remove all the DataSync related objects (tables, triggers etc)?

Answer 1

I recently ran into this issue and while the script in the accepted answer did remove the DataSync schema, it did not remove the dss or TaskHosting schemas nor the symmetric key objects that were preventing me from exporting my database.

I ended up needing to contact Azure support to get everything removed. Here is the script that they gave me:

declare @n char(1)

set @n = char(10)



declare @triggers nvarchar(max)

declare @procedures nvarchar(max)

declare @constraints nvarchar(max)

declare @views nvarchar(max)

declare @FKs nvarchar(max)

declare @tables nvarchar(max)

declare @udt nvarchar(max)



-- triggers

select @triggers = isnull( @triggers + @n, '' ) + 'drop trigger [' + schema_name(schema_id) + '].[' + name + ']'

from sys.objects

where type in ( 'TR') and name like '%_dss_%'



-- procedures

select @procedures = isnull( @procedures + @n, '' ) + 'drop procedure [' + schema_name(schema_id) + '].[' + name + ']'

from sys.procedures

where schema_name(schema_id) = 'dss' or schema_name(schema_id) = 'TaskHosting' or schema_name(schema_id) = 'DataSync'



-- check constraints

select @constraints = isnull( @constraints + @n, '' ) + 'alter table [' + schema_name(schema_id) + '].[' + object_name( parent_object_id ) + ']    drop constraint [' + name + ']'

from sys.check_constraints

where schema_name(schema_id) = 'dss' or schema_name(schema_id) = 'TaskHosting' or schema_name(schema_id) = 'DataSync'



-- views

select @views = isnull( @views + @n, '' ) + 'drop view [' + schema_name(schema_id) + '].[' + name + ']'

from sys.views

where schema_name(schema_id) = 'dss' or schema_name(schema_id) = 'TaskHosting' or schema_name(schema_id) = 'DataSync'



-- foreign keys

select @FKs = isnull( @FKs + @n, '' ) + 'alter table [' + schema_name(schema_id) + '].[' + object_name( parent_object_id ) + '] drop constraint [' + name + ']'

from sys.foreign_keys

where schema_name(schema_id) = 'dss' or schema_name(schema_id) = 'TaskHosting' or schema_name(schema_id) = 'DataSync'



-- tables

select @tables = isnull( @tables + @n, '' ) + 'drop table [' + schema_name(schema_id) + '].[' + name + ']'

from sys.tables

where schema_name(schema_id) = 'dss' or schema_name(schema_id) = 'TaskHosting' or schema_name(schema_id) = 'DataSync'



-- user defined types

select @udt = isnull( @udt + @n, '' ) +

    'drop type [' + schema_name(schema_id) + '].[' + name + ']'

from sys.types

where is_user_defined = 1

and schema_name(schema_id) = 'dss' or schema_name(schema_id) = 'TaskHosting' or schema_name(schema_id) = 'DataSync'
