我如何基于另一个表中的值创建重复记录 [英] How can i create duplicate records based the value in another table

问题描述

我的数据库中有两个表， Work_Order 表是存储工作订单信息的源表，我也有 Work_Schedule 表，其中包含工作时间表，这些工作表告诉人们生产车间要建造什么，何时建造以及要建造多少.

Work_Order表看起来像

 工单ItemCode大小数量Qty_per_HR41051 600111 14L-16.1 55 10 

我想根据每小时工时在上面的工作单表中复制上述工作单行，并自动创建工作计划程序，如下所示.

其中 TARGET = Work_Order.Qty/Work_Order.Qty_per_HR

工作时间表表

  Id开始日期/时间结束日期/时间工作订单工作中心TARGET ACTUAL1001 2019-07-22 7:00 AM 2019-07-22 8:00 AM 41051 1 101001 2019-07-22 8:00 AM 2019-07-22 9:00 AM 41051 1 101001 2019-07-22 9:00 AM 2019-07-22 10:00 AM 41051 1 101001 22019-07-22 10:15 AM 2019-07-22 11:00 AM 41051 1 101001 22019-07-22 11:00 AM 2019-07-22 12:00 PM 41051 1 101001 2019-07-22 1:30 PM 2019-07-22 2:30 PM 41051 1 5 

我的计划是在用户工作单创建重复项后立即使用 AfterInsert 触发器.

解决方案

对于递归CTE，这似乎很自然:

 ，cte为(选择convert(datetime，'2019-07-22 7:00 AM')作为dt，工作单，1作为工作中心，qtyperh作为目标，itemcode，size，(qty-qtyperh)as qty，qtyperh从T全部合并选择dateadd(hour，1，dt)，工作单，工作中心，(如果qty> qtyperh然后qtyperh否则qty结束)作为目标，项目代码，大小，(数量-qtyperh)，qtyperh来自cte数量>0)选择cte.*，dateadd(second，60 * 60 * target/qtyperh，dt)作为end_dt来自cte按工作单排序，dt； 

这里是db< fiddle.

I have two tables in my database, Work_Order table which is the source table where work order information's stored i also have Work_Schedule table which contains work schedules which tell peoples in the production floor what to build, when and how much to build.

Work_Order Table looks like

Work order  ItemCode    Size          Qty    Qty_per_HR 
41051        600111    14L-16.1        55          10

I want duplicate the above work order line in work order table above based on the Qty per hour and automatically create a work scheduler as shown below.

where TARGET = Work_Order.Qty/Work_Order.Qty_per_HR

Work_Schedule Table

Id      Start Date/Time        End Date/Time       Work Order       Work Center     TARGET   ACTUAL
1001    2019-07-22 7:00AM      2019-07-22 8:00AM       41051             1         10       
1001    2019-07-22 8:00AM      2019-07-22 9:00AM       41051             1         10    
1001    2019-07-22 9:00AM      2019-07-22 10:00AM      41051             1         10    
1001    22019-07-22 10:15AM    2019-07-22 11:00AM      41051             1         10    
1001    22019-07-22 11:00AM    2019-07-22 12:00PM      41051             1         10  
1001    2019-07-22 1:30PM      2019-07-22 2:30PM       41051             1         5      

My plan is to use AfterInsert trigger as soon as the user a work order create the duplicates.

解决方案

This seems like a natural for a recursive CTE:

with cte as (
      select convert(datetime, '2019-07-22 7:00AM') as dt, workorder, 1 as workcenter, qtyperh as target,
             itemcode, size, (qty - qtyperh) as qty, qtyperh
      from t
      union all
      select dateadd(hour, 1, dt), workorder, workcenter,
             (case when qty > qtyperh then qtyperh else qty end) as target,
             itemcode, size, (qty - qtyperh), qtyperh
      from cte
      where qty > 0
     )
select cte.*,
       dateadd(second, 60 * 60 * target / qtyperh, dt) as end_dt
from cte
order by workorder, dt;

Here is a db<>fiddle.
