mysql - 如何使用来自不同表的查询结果填充一个表？

Question

我创建了一个查询，该查询可以工作并提供我想要的内容，但它不会在批处理文件中执行。如何使用成功执行的查询的结果填充另一个表？

这是我的查询

select  

isnull (start_charge.account,'No account at start') Start_charge_account
,Finish_charge.account start_charge_account   
,case when start_charge.account is null then finish_charge.account else       start_charge.account end "account" 
,isnull (start_charge.Branch,99999999999) Start_charge_Branch
,Finish_charge.Branch Finish_charge_Branch
,case when start_charge.branch is null then finish_charge.branch else  start_charge.branch end " branch"
,isnull (start_charge. site_number,99999999999) Start_charge_site_number
,Finish_charge. site_number Finish_charge_site_number
,case when start_charge.site_number is null then finish_charge.site_number else start_charge.site_number end "site_number"
,isnull (start_charge. service_code, 'No account at start') Start_charge_service_code
,Finish_charge. service_code finish_charge_service_code
,isnull (start_charge. item_code,'No account at start') Start_charge_item_code
,Finish_charge. item_code finish_charge_item_code
,isnull (start_charge. why_code, 'No account at start') Start_charge_why_code
,Finish_charge. why_code finish_charge_why_code
,isnull (start_charge. why_type, 'No account at start') Start_charge_why_type
,Finish_charge. why_type finish_charge_why_type

,Start_charge.Start_charge
,isnull(Finish_charge.Finish_charge,0) Finish_charge
,isnull(Start_charge.Start_charge,0)-isnull(Finish_charge.Finish_charge,0) Variance


from

select

account

有两种处理方法:

CREATE TABLE mytable AS
  (SELECT ... )

将使用查询结果创建一个新表。

INSERT INTO mytable (field1, field2, ...)
  (SELECT ... )

会将查询结果插入到现有表中。当然，您需要确保列列表匹配。如果查询返回的列列表与您现有的表完全匹配，那么您不需要指定字段列表，您的语句就会变得简单

INSERT INTO mytable (SELECT ... )
