SQL Server：通过SQL查询导出数据？

Question

I have FK and PK all over my db and table data needs to be specified in a certain order or else I get FK/PK insertion errors. I'm tired of executing the wizard again and again to transfer data one table at a time.

In the SQL Server export data wizard there is an option to "Write a query to specify the data to transfer". I'd like to write the query myself and specify the correct order.

1. Will this solve my problem?

2. How do I do this? Can you provide a sample query (or link to one)

   • The databases are on two different servers - SQL Server 2008 on each ; The database names & permissions are the same ; each table name & col is the same ; I need Identity Insert for each table.

Answer 1

Disable foreign keys before importing, enable them after the import:

ALTER TABLE tablename NOCHECK CONSTRAINT ALL

ALTER TABLE tablename WITH CHECK CHECK CONSTRAINT ALL

Update: Thanks for the comments, I fixed the syntax.

Answer 2

您可以始终保存该程序包，然后打开并编辑该程序包以按正确的顺序放置内容（您可能必须多次复制数据流并在它们之间放置依赖项）

Answer 3

You can use 3rd party tools to transfer a data; these tools disable/enable constraints automatically.
