无法在node-sqlite3中执行此操作（使用for循环）

Question

我需要在node-sqlite3中获得相同的结果，因为我想在rest api中使用它，并且它必须是异步的。我该怎么办？

当我在for循环的node-sqlite3中尝试它时，结果总是随机的。我不明白为什么。请帮助我。

我认为这与node-sqlite3的异步性有关。但是后来我意识到我需要它是异步的。

在Better-sqlite3中

const Database = require('better-sqlite3');

const tsePath = './tseFiles/94-ENAR-000.tse';

const db = new Database(tsePath);

let rows = [];

const sqlGetLastId = db.prepare("SELECT COUNT(ROWID) AS countFilledIn FROM WRITE WHERE T2 not null");
const sqlGetLatestRead = db.prepare("SELECT * FROM READ WHERE ROWID = ?");
const sqlGetLanguage = db.prepare("SELECT Dir, Subtag FROM EXTDIR WHERE LangID=?");

const count = sqlGetLastId.get().countFilledIn;
for (let i = 1; i <= count; i++) {
   let option = {
      id: i,
      sourceLang: "",
      sourceDir: "",
      sourceText: "",
      translationLang: "",
      translationDir: "",
      translationText: ""
   };
   const result1 = sqlGetLatestRead.get(i);
   option.sourceText = result1.source_text;
   option.translationText = result1.translated_text1;
   const sourceLanguage = result1.source_language;
   const translationLanguage = result1.target_language;
   const result2 = sqlGetLanguage.get(sourceLanguage);
   option.sourceLang = result2.Subtag;
   option.sourceDir = result2.Dir;
   const result3 = sqlGetLanguage.get(translationLanguage);
   option.translationLang = result3.Subtag;
   option.translationDir = result3.Dir;
   rows.push(option);
}

console.log(rows);


The output is:
