mysqld_stmt_execute 的参数不正确，参数匹配查询

Question

我正在尝试使用

LIKE

使用 mysql2 搜索 mysql 表中的行，但我在控制台中收到有关参数不正确的错误。准备好的语句的参数与查询字符串的需求相匹配。

代码：

import mysql from "mysql2";

export const searchMovies = (phrase: string, limit: number): Promise<Movie[]> => {
    return new Promise((resolve, reject) => {
        const pattern = `%${phrase.replace("!", "!!").replace("%", "!%").replace("_", "!_")}%`;
        const sql = "SELECT * FROM movies WHERE `Name` LIKE ? LIMIT ?";
        const params = [pattern, limit];
        db.execute(sql, params, (err, rows: RowDataPacket[]) => {
            if (err) reject(err);
            if (rows == undefined) return [];
            resolve(rows.map(x => ({
                id: x.ID,
                name: x.Name,
                language: x.Language,
                year: x.Year
            })));
        });
    });
};

控制台错误：

/home/node/app/node_modules/mysql2/lib/packets/packet.js:728
    const err = new Error(message);       
                ^

从“mysql2”导入mysql；

export const searchMovies =（短语：字符串，限制：数量）：Promise => { 返回新的 Promise((解决, 拒绝) => { const 模式 =

%${phrase.replace("!", "!!").replace("%", "!%").replace("_", "!_")}%

; const sql = "从电影中选择 *

Name

LIKE ? LIMIT ?"; const params = [模式，限制]； db.execute(sql, params, (err, rows: RowDataPacket[]) => { 如果（错误）拒绝（错误）； if (行==未定义) return []; 解析（rows.map（x =>（{ id：x.ID， 姓名：x.姓名， 语言：x.语言， 年份: x.Year }）））； }); }); };
