Question

在MS Access中，我已连接到具有只读访问权限的外部Oracle数据库表。该表跟踪文章（prodnr）的制作过程。在目标金额完成之前，可能会在一次运行或多次运行中生成一篇文章。

如何从该表中获取完整的AMOUNT（completekz = 1）或SUM（AMOUNT）（仅限completekz = 0条目）。

import express from 'express';
import path from 'path';

import webpack from 'webpack';
import webpackMiddleware from 'webpack-dev-middleware';
import webpackHotMiddleware from 'webpack-hot-middleware';
import webpackConfig from '../webpack.config.dev';

let app = express();
const compiler = webpack(webpackConfig);

app.use(webpackMiddleware(compiler, {
  hot: true,
  publicPath: webpackConfig.output.publicPath,
  noInfo: true,
}));
app.use(webpackHotMiddleware(compiler));

app.use('/assets',express.static(__dirname + '/assets'));


app.get('/*', (req, res) => {
  res.sendFile(path.join(__dirname,'../index.html'));
})

app.listen(3000, () => console.log('Running port 3000'));

这是我的查询返回所有四行。我似乎无法找到正确的方法。

PRODNR COMPLETEKZ BACOMPLETEKZ     AMOUNT
------ ---------- ------------ ----------
   ...            ...                 ...
    16 0          partial             500
    16 0          partial           20000
    16 0          partial            8000
    16 1          complete          40000
    17 1          complete            100
    18 0          partial           10000
    18 0          partial            1500
    19 1          complete          35000
   ...            ...                 ...

Answer 1

考虑

此

SELECT Q1.prodnr, Sum(IIf(([completekz]=1 And [MaxComp]=1) Or ([completekz]=0 And [MaxComp]=0),[Amount],0)) AS SumAmt FROM (SELECT aforueck.prodnr, aforueck.completekz, aforueck.bacompletekz, aforueck.amount, DMax("Completekz","aforueck","Prodnr='" & [prodnr] & "'") AS MaxComp FROM aforueck) AS Q1 GROUP BY prodnr;

或

SELECT aforueck.prodnr, Sum(IIf(([completekz]=1 And [MaxComp]=1) Or ([completekz]=0 And [MaxComp]=0),[Amount],0)) AS SumAmt FROM (SELECT aforueck.PRODNR, Max(aforueck.COMPLETEKZ) AS MaxComp FROM aforueck GROUP BY aforueck.PRODNR) AS Q1 INNER JOIN aforueck ON Q1.PRODNR = aforueck.PRODNR GROUP BY aforueck.prodnr;

两者都返回：
+--------+--------+ | prodnr | SumAmt | +--------+--------+ | 16 | 40000 | | 17 | 100 | | 18 | 11500 | | 19 | 35000 | +--------+--------+

这符合“完整AMOUNT（completekz = 1）或SUM（AMOUNT）（仅限completekz = 0条目）”的描述。如果这不是所需的输出，请提供一个示例。
