有一个BOM表，表中很多记录的一个关键字（比如product_id）都是一样的值(比如都是“AAA”)
我想新建记录，直接从所有“AAA”的记录拷贝到“BBB”
用存储过程如何写？
- SQL code
CREATE PROCEDURE [dbo].[CopyNode]( @product_id varchar(25), @product_id_new varchar(25))ASdeclare @lft intdeclare @rgt intif exists(select product_id from BOM where product_id = @product_id) begin SET XACT_ABORT ON BEGIN TRANSACTION select * from BOM where product_id = @product_id //如何写呢？ //insert into BOM where product_id = @product_id COMMIT TRANSACTION SET XACT_ABORT OFF end
------解决方案--------------------
select * from BOM where product_id = @product_id
//如何写呢？
//insert into BOM where product_id = @product_id
:
insert into bom
select 除了product_id 列外的其他所有列,'BBB'
from bom where product_id='AAA'
注意上面product_id在字段列表中的位置.
------解决方案--------------------
- SQL code
SET XACT_ABORT ONBEGIN TRANSACTION insert into BOM select @product_id_new,[product_id外的其他字段] from BOM where product_id = @product_idCOMMIT TRANSACTION
------解决方案--------------------
- SQL code
insert into BOM select @product_id_new,其他字段 from BOM where product_id = @product_id
------解决方案--------------------
SET XACT_ABORT ON
BEGIN TRANSACTION
insert into BOM
select @product_id_new,[product_id外的其他字段]
from BOM where product_id = @product_id
COMMIT TRANSACTION
