如何在 QUERY-PREPARE() 中使用 last-of？

如何解决如何在 QUERY-PREPARE() 中使用 last-of？

我编写了一个巨大的代码，需要很长时间来处理。按照这里的建议，我把它做得更短更好，现在它运行得更快了。但是，我注意到我应该得到这些值的总和，而我只是得到了这些值。我尝试使用 ACCUMULATE TOTAL，但它不起作用，因为 LAST-OF 只能与 BREAK BY 一起使用，而我的 break by 位于 QUERY-PREPARE() 内。

如何获得以下值的总和？

doc-fiscal.vl-cont-doc
doc-fiscal.vl-bicms
doc-fiscal.vl-icms
doc-fiscal.vl-icmsou
doc-fiscal.vl-ipIoU
doc-fiscal.vl-ipi

Bellow 是我正在使用的代码，它几乎完美运行。

//Query
cQuery = "FOR EACH doc-fiscal WHERE doc-fiscal.dt-docto >= " + QUOTER(pd-data-1) + " AND doc-fiscal.dt-docto <= " + QUOTER(pd-data-2) + " AND (doc-fiscal.cod-observa <> 4 OR doc-fiscal.tipo-nat <> 3) AND doc-fiscal.cd-situacao <> 06 AND doc-fiscal.cd-situacao <> 22".
cQuery = cQuery + semCodEmitente + comCodEmitente + CheckBoxindSitDoc.
cQuery = cQuery + ",EACH natur-oper USE-INDEX natureza WHERE doc-fiscal.nat-operacao = natur-oper.nat-operacao" + modeloEletronico + tipoEnTrada + natOper.
cQuery = cQuery + " BREAK BY doc-fiscal.dt-docto BY doc-fiscal.nr-doc-fis ".

QUERY qRelatorio:QUERY-PREPARE(cQuery).

QUERY qRelatorio:QUERY-open().

GET FirsT qRelatorio.
DEF VAR soma-vl-cont-doc AS DECIMAL.
do while AVAILABLE doc-fiscal:
    
    soma-vl-cont-doc = soma-vl-cont-doc + doc-fiscal.vl-cont-doc.

    IF LAST-OF(doc-fiscal.nr-doc-fis) THEN DO:
    CREATE tt-relatorio.
    ASSIGN
    tt-relatorio.nr-doc-fis = doc-fiscal.nr-doc-fis
    tt-relatorio.serie = doc-fiscal.serie
    tt-relatorio.char-2 = SUBSTRING(doc-fiscal.char-2,155,44,"CHAR")
    tt-relatorio.cod-model-nf-eletro = natur-oper.cod-model-nf-eletro
    tt-relatorio.tipo = natur-oper.tipo
    tt-relatorio.cod-estabel = doc-fiscal.cod-estabel
    tt-relatorio.cod-emitente = doc-fiscal.cod-emitente
    tt-relatorio.nome-ab-emi = doc-fiscal.nome-ab-emi
    tt-relatorio.cgc = doc-fiscal.cgc
    tt-relatorio.dt-emis-doc = doc-fiscal.dt-emis-doc
    tt-relatorio.dt-docto = doc-fiscal.dt-docto
    tt-relatorio.ind-sit-doc = doc-fiscal.ind-sit-doc
    tt-relatorio.vl-cont-doc = doc-fiscal.vl-cont-doc
    tt-relatorio.vl-bicms = doc-fiscal.vl-bicms
    tt-relatorio.vl-icms = doc-fiscal.vl-icms
    tt-relatorio.vl-icmsou = doc-fiscal.vl-icmsou
    tt-relatorio.vl-ipIoU = doc-fiscal.vl-ipIoU
    tt-relatorio.vl-ipi = doc-fiscal.vl-ipi
    tt-relatorio.imp-nota = natur-oper.imp-nota.
    
    GET NEXT qRelatorio.
    END.
END.

QUERY qRelatorio:QUERY-CLOSE().

感谢您的帮助，很抱歉我是个新手。我希望我的问题可以帮助其他人。

解决方法

我设法做到了。我使用了 LAST-OF() 方法。我的代码变成了以下。

public string RandomPassword() {
  string lettre = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz";
  string caractere = "!-_*+&$";
  string number = "0123456789";
  string ensemble = "";
  ensemble += lettre;
  ensemble += number;
  ensemble += caractere;

  // Ici,ensemble contient donc la totalité des caractères autorisés

  string password = "";
  int taillePwd = 8;
  Random rand = new Random();
  for (int i = 0; i < taillePwd; i++) {
    // On ajoute un caractère parmi tous les caractères autorisés
    password += ensemble[rand.Next(0,ensemble.Length)];
  }
  return password;
}

有了这个，我设法得到了我想要的答案，而且查询速度非常快。如果有任何关于如何使其更快的建议，我愿意接受。谢谢。
