我在visual studio 2008的查询窗格中生成了一个错误，我似乎无法弄清楚。
函数参数列表出错：'='无法识别。无法解析查询文本。
在对语法进行一些清理并添加一些正确的引用后，问题仍然存在。无论如何我试图执行查询，最终在visual studio 2008中无休止地等待。
这是查询。

我正在使用ODBC，连接字符串包含Driver = {UNIMS}。这是一个非常古老的数据库，我必须在我的应用程序中支持。
某处的语法可能有问题，但我看不到它。
EDIT1： 以下是UNIMS数据库中“WORKS”的示例条件代码。 （取自旧应用程序中的AnsiString。）
condition(leg.tstohn = '" + pAuthorization[7] + "', shipment.pllaad, shipment.pllos)
condition(leg.tstohn = '" + pAuthorization[7] + "', shipment.tslzcd, shipment.tsuzcd)
condition(leg.tstohn = '" + pAuthorization[7] + "', shipment.lalaad, shipment.lalos)
condition(leg.tstohn = '" + pAuthorization[7] + "', shipment.nmlaad, shipment.nmlos) zkafz
condition(leg.tstohn = '" + pAuthorization[7] + "', shipment.adrlaa, shipment.adrlos)
EDIT2：
也无法找到有关UNIMS SQL UNIMS SQL的大量文档。这里有更多可能有用的信息。

Edit4： 当我删除下面的案例时，我注意到查询是无穷无尽的。我想我将首先重新考虑我的ODBC连接。
Edit5： 在大多数情况下，似乎不能在PuTTY中工作或直接在机器上工作。由于某种原因，它最终会在资源占用查询中结束。新方法：在PuTTY中使用正确的查询解决了问题，但在ODBC Unims
中尚未接受此问题 select

leg.tsrnum,
dosier.dosvlg,
condition(leg.tsakti = 1, dosier.lalaad, dosier.lalos),

最终修改：
尽管visual studio无法识别条件的unims语法，但上面的代码仍能正常工作。根据服务器，旧查询被卡住并且大小超过100 MB，从而杀死了这些进程。 10年的数据库确实很奇怪。
答案 0 :(得分：2)
我不熟悉UniMS，但也许下列之一可行：
(case when leg.tsakti = 1 then load.land else unload.land end),
(case when condition(leg.tsakti = 1 then load.postun else unload.postun end),
(case when condition(leg.tsakti = 1 then load.tsadr1 else unload.tsadr1 end)
或：
iif(leg.tsakti = 1, load.land, unload.land),
iif(leg.tsakti = 1, load.postun, unload.postun),
iif(leg.tsakti = 1, load.tsadr1, unload.tsadr1)
或：
if(leg.tsakti = 1, load.land, unload.land),
if(leg.tsakti = 1, load.postun, unload.postun),
if(leg.tsakti = 1, load.tsadr1, unload.tsadr1)
这些在其他一些数据库中有效。
