Question

我需要运行一个if else语句，然后在其中运行一个map，否则运行查询，但是它只是作为异步运行。

下面的代码已损坏。我不知道如何解决它。

function newRank() {
    return new Promise((resolve, reject) => {
        // If the select from target table is empty, then run this if below
        if (rank_atual.length == 0) {
            console.log('RANK ATUAL IF')
            // Map new rank to add into target table
            rank_gender.map(async (rnk) => {
                // Query that will be feed by rank array and put that on the target table
                let sql_insert = `INSERT INTO rnk_rank_diario (nr_rank_sem_genero, qt_tocadas, fk_id_fonogramas, fk_id_artista, fk_id_rnk_local_record, fk_id_rnk_tipo_emissora, fk_id_rnk_relevancia_local, fk_id_rnk_tipo_emissora_nr_relevancia, dh_sem_genero_criado, dh_sem_genero_alterado, nr_rank_com_genero, dh_com_genero_criado, dh_com_genero_alterado, fl_ativo, fk_id_fonogramas_genero, fl_record_sem_genero, fl_record_com_genero) VALUES (${rnk.rank}, ${rnk.total}, ${rnk.fonograma}, ${rnk.artista}, 1, ${rnk.categoria}, 5, 5, current_timestamp(), NULL, ${rnk.rank_genero}, current_timestamp(), NULL, 1, ${rnk.genero}, 1, 1)`;
                // console.log(sql_insert)
                // Run the query above, and check if everything goes fine.
                conInsert.query(sql_insert, function (err, result) {
                    if (err) return reject(err);
                })
            })
        }
else {
    console.log('RANK ATUAL ELSE')
    // Map new rank to add into target table
    rank_gender.map((rnk) => {
        // Find the index on the actual rank using the new rank fonogram
        let ra = rank_atual.findIndex(obj => obj.fk_id_fonogramas == rnk.fonograma)

        if (ra > 0) {

            if (rnk.rank < rank_atual[ra].nr_rank_sem_genero && rnk.rank_genero < rank_atual[ra].nr_rank_com_genero ) {
                // console.log(rank_atual[ra + 1].nr_rank_sem_genero)
                // Query to update the old record changing the date and the flag to set inactive
                let sql_update = `UPDATE rnk_rank_diario SET dh_sem_genero_alterado = current_timestamp(), dh_com_genero_alterado = current_timestamp(), fl_ativo = 0 WHERE fk_id_fonogramas = ${rank_atual[ra].nr_rank_sem_genero} AND fk_id_rnk_local_record = 1 AND fk_id_rnk_tipo_emissora = 5 AND fl_ativo = 1;`;

这是代码正在执行的示例，而不是等待完成并运行

5. newRank rodou ok

当屏幕上显示5. newRank rodou ok时，然后通过全部if else语句传递后，查询开始运行，我是否丢失了某些内容？

为什么即使我有Promise和await值，我的代码仍为什么以异步方式运行
