Javascript 如何避免在节点sqlite[knex，objectionJS]中插入重复记录

我从api中提取数据并存储到数据库中，下面是我从api中获取的值：

const optAdThisMonthsResult =  [
            [ 'google.com', 'Display', '2021-02-01', 3, 48, 76 ],
            [ 'google.com', 'a1.php', '2021-02-01', 94, 31, 42 ],
        ]

获取后，我将其存储在数据库中：

for (const data of optAdThisMonthsResult) {

        //1. Assign values to store
        let rowData = {
            url: data[0],
            tags: data[1],
            date: data[2],
            value1: data[3],
            value2:data[4],
            value3: data[5],
        };

        //2. Store to database
        let ret = await OptAd.query().insert(rowData);
        console.log(
            `Inserted OptAd data with return code: ${require("util").inspect(ret)}`
        );
    }

---

每次我运行这个脚本时，它也会存储数据库中已经存在的重复值，如果数据已经存在，我如何为此构建测试？不要插入，只更新此

value1

value2

value3

首先尝试使用Knex进行更新，如果返回零行更新，请尝试插入

for (const data of optAdThisMonthsResult) {
  //1. Assign values to store
  let rowData = {
    url: data[0],
    tags: data[1],
    date: data[2],
    value1: data[3],
    value2: data[4],
    value3: data[5],
  };

  // get count first
  const result = await OptAd.query()
    .count("tags as count")
    .where({ url: data[0], taga: data[1], date: data[2] })
    .first();
  try {
    if (result.count === 0) {
      // row not present insert data
      let ret = await OptAd.query().insert(rowData);
      console.log(
        `Inserted OptAd data with return code: ${require("util").inspect(ret)}`
      );
    } else {
      // row already presnt do update
      // checking if its not updated
      const { count } = await OptAd.query()
        .count("tags as count")
        .where(rowData)
        .first();
      if (count === 0) {
        const updated = await OptAd.query()
          .update(rowData)
          .where({ url: data[0], taga: data[1], date: data[2] });
        console.log("updated");
      } else {
        console.log("Not Changed");
      }
    }
  } catch (error) {
    console.log(error.message);
  }
}
