Question

我有3张桌子：

for line in <your results set>:
    line = line.rstrip()
    if '^Referer:' in line) :
        print line

我想做一个查询，显示JCTransactions表中的所有记录，但是有工作描述，成本代码描述和顶级成本代码描述。

例如：

1) JCTransactions
Job         CostCode    Date        Amount
36801-001   01-150      1/8/2015    55.00
36801-001   02-240      2/6/2015    26.00

2) JCCostCode
Job         CostCode    Description
36801-001   01-000      Land
36801-001   01-150      Land Legal Fees
36801-001   02-000      Holding Costs
36801-001   02-240      Property Taxes

3) JCJob
Job         Description
36801-001   BusinessCenter1
36901-001   BusinessCenter2(NotYetStarted)

我无法将TopLevelCostCode及其描述添加到结果中。

到目前为止我的代码运行良好，但它没有我想要的最后一列：

Job         CostCode    Date        Amount  JobDesc         CostCodeDesc    TopLevelCostCode    TopLevelCodeDesc
36801-001   01-150      1/8/2015    55.00   BusinessCenter1 Land Legal Fees 01-000              Land
36801-001   02-240      2/6/2015    26.00   BusinessCenter1 Property Taxes  02-000              Holding Costs

Answer 1

select * from JCCOSTCODE
select * from JCJOB 
select * from JCTRANSACTIONS

select Res1.job,Res1.costcode,res1.date,res1.amount,res1.jobdesc,res1.costdesc,res2.topLevelCode,res2.TopLevelCodeDesc from (
SELECT  JCTRANSACTIONS.Job,
JCTRANSACTIONS.CostCode,
JCTRANSACTIONS.Date,
JCTRANSACTIONS.Amount,
JCJOB.Description jobdesc,
JCCOSTCODE.Description as costdesc ,
row_number() over(order by JCTRANSACTIONS.CostCode) rowid
FROM JCCOSTCODE JCCOSTCODE
inner join JCJOB JCJOB on JCCOSTCODE.Job = JCJOB.Job
inner join   JCTRANSACTIONS JCTRANSACTIONS on JCJOB.Job = JCTRANSACTIONS.Job and JCCOSTCODE.CostCode = JCTRANSACTIONS.CostCode) Res1 inner join (
select costcode as topLevelCode, Description as TopLevelCodeDesc, ROW_NUMBER() over (order by costcode ) rowid from JCCOSTCODE where costcode not in (select costcode from JCTRANSACTIONS)) res2
on Res1.rowid = Res2.rowid

SQL查询从另一个表中查找2个值
