Question

当我在Database Workbench中运行它时，这个SQL（Firebird 2.5，方言1）查询工作正常，但是当我在IBO控制台下运行它时它失败了：

列列表和变量列表的计数不匹配。

如果我在IBO控制台下单独运行这两个查询，那么这两个查询会成功运行，所以我推断问题是因为＆＃34; Union。＆＃34;列的数量和类型匹配两个查询 - 返回字符串，smallint，字符串（IBO控制台将此视为备忘录），字符串 - 因此Union应该有效（并且DB Workbench会发现它）。考虑到数据的长度可能不同，我尝试将第三列作为VarChar（500）进行投射，但这并没有帮助。寻找关于为什么这不起作用的想法，因为我们的应用程序正在执行查询的部分显然是以与IBO控制台相同的方式窒息。

Select QBI.TXNID as ID,
  Cast (1 as SmallInt) as TransactionType,
  ("Invoice " || QBI.REFNUMBER || ": $" || round(QBI.SUBTOTAL, 2) || " on " || QBI.TXNDATE || " for " || QBI.CUSTOMERREF_FULLNAME) as description,
  case
    when (QBI.CLASSREF_LISTID = "") then "Invoice has no class in Quickbooks"
    else "Invoice class doesn't match any dept on job " || JA.JOBID
  end as Problem
from QBINVOICE QBI
Join JOBACCOUNTINGID JA
  on QBI.CUSTOMERREF_LISTID = JA.jobaccountingid
  and QBI.SOURCEID = JA.SOURCEID
left Join CHARTOFACCOUNTS CA
  on (CA.qblistid = QBI.CLASSREF_LISTID and CA.qbsourceID = QBI.SOURCEID)
  and CA.CHARTACCOUNTTYPE = "SYSTEM"
  and CA.CHARTFETCH = "Y"
left Join DEPARTMENTJOB DJ
  on JA.JOBID = DJ.JobID
  and DJ.departmentID = CA.DEPARTMENTID
where DJ.DEPARTMENTID is null
  and QBI.TXNDATE >= "02/01/2017"

union all

select 
  QBELD.TXNLINEID as ID, 
  Cast (2 as SmallInt) as TransactionType,
