如何手动删除SQL Azure数据同步对象

Question

放弃SQL Azure Data Sync以在两个SQL Azure数据库之间同步数据，如何删除所有与DataSync相关的对象（表，触发器等）？

例如：

DataSync.<table>_dss_tracking
DataSync.schema_info_dss
DataSync.scope_config_dss
DataSync.scope_info_dss

还有其他所有物品吗？是否有可以运行的脚本？

Answer 1

msgooroo.com上有一篇文章：

https://msgooroo.com/GoorooTHINK/Article/15141/Removing-SQL-Azure-Sync-objects-manually/5215

基本上脚本如下：

-- Triggers
DECLARE @TRIGGERS_SQL VARCHAR(MAX) = (
    SELECT
        'DROP TRIGGER [' + SCHEMA_NAME(so.uid) + '].[' +  [so].[name] + '] ' 
        FROM sysobjects AS [so]
        INNER JOIN sysobjects AS so2 ON so.parent_obj = so2.Id
        WHERE   [so].[type] = 'TR'
        AND     [so].name LIKE '%_dss_%_trigger'
    FOR XML PATH ('')
)
PRINT @TRIGGERS_SQL
IF LEN(@TRIGGERS_SQL) > 0
BEGIN
    EXEC (@TRIGGERS_SQL)
END     


-- Tables
DECLARE @TABLES_SQL VARCHAR(MAX) = (
    SELECT
        'DROP TABLE [' + table_schema + '].[' + table_name + '] ' 
    FROM 
        information_schema.tables where table_schema = 'DataSync' 
    FOR XML PATH ('')
)
PRINT @TABLES_SQL
IF LEN(@TABLES_SQL) > 0
BEGIN
    EXEC (@TABLES_SQL)
END    

-- Stored Procedures
DECLARE @PROC_SQL VARCHAR(MAX) = (
    SELECT 'DROP PROCEDURE [' + routine_schema + '].[' + routine_name + '] ' 
    FROM    INFORMATION_SCHEMA.ROUTINES where ROUTINE_SCHEMA = 'DataSync' and routine_type = 'PROCEDURE'
    FOR XML PATH ('')
)
PRINT @PROC_SQL
IF LEN(@PROC_SQL) > 0
BEGIN
    EXEC (@PROC_SQL)
END    


-- Types
DECLARE @TYPE_SQL VARCHAR(MAX) = (
  SELECT
  'DROP TYPE [' + SCHEMA_NAME(so.uid) + '].[' + [so].[name] + '] ' 
  FROM systypes AS [so]
  where [so].name LIKE '%_dss_bulktype%'
  AND SCHEMA_NAME(so.uid) = 'Datasync'
  FOR XML PATH ('')
)
PRINT @TYPE_SQL
IF LEN(@TYPE_SQL) > 0
BEGIN
  EXEC (@TYPE_SQL)
END    


-- Schema
DROP SCHEMA DataSync    

Answer 2

我最近遇到了这个问题，尽管接受的答案中的脚本确实删除了DataSync架构，但是它没有删除阻止我导出数据库的dss或TaskHosting架构，也没有删除对称密钥对象。

我最终需要联系Azure支持以删除所有内容。这是他们给我的脚本：

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 + ']'

Answer 3

如果您的Azure和SQL Server之间的体系结构仍然存在 - 您只需从SQL数据同步代理中取消注册即可删除上述对象。

Answer 4

Microsoft不久前发布了此script。如果您需要删除单个表，则非常方便

declare @TableName nvarchar(max)
set @TableName = 'yourTableName'
--In case you wish to delete objects related to all the tables you can uncomment the following:
--set @TableName = ''

-- Generate the script to drop Data Sync tables
select 'drop table [DataSync].['+ st.name+ '];' from sys.tables as st join sys.schemas as ss on ss.schema_id = st.schema_id 
where ss.name = 'DataSync' and st.name like '%' + @TableName + '_dss_%'

-- Generate the script to drop Data Sync stored procedures
select 'drop procedure [DataSync].['+ sp.name+ '];' from sys.procedures as sp join sys.schemas as ss on ss.schema_id = sp.schema_id 
where ss.name = 'DataSync' and sp.name like '%' + @TableName + '_dss_%'

-- Generate the script to delete Data Sync triggers
select 'drop trigger [' + schema_name(schema_id) + '].[' + name + ']'
from sys.objects where type = 'TR' and name like '%' + @TableName + '_dss_%'

-- Generate the script to delete Data Sync-related udtt
select 'drop type  [DataSync].['+ st.name+ '];' from sys.types as st join sys.schemas as ss on st.schema_id = ss.schema_id 
where ss.name = 'DataSync' and st.name like '%' + @TableName + '_dss_%'

如果您在本地 SQL Server 上进行了同步设置，从 Azure 同步代理界面取消注册数据库将进行必要的清理。
