【问题描述】：

我的查询是这样的：

let query = `SELECT id, name FROM students WHERE school_code = "${schoolCode}" AND name REGEXP "${text}" `;

还有参数：

let params = [ schoolCode, text ];
let query = `SELECT id, name FROM students WHERE school_code = "?" AND name REGEXP "?" `

Model.dataSource.connector.query(query, params, (err, res) => {} );

这行不通

（下面的解决方案）

【解决方案1】：

我以为可能是 REGEXP 但

解决方案是：

删除问号周围的引号。

例如，这行得通：

let params = [ schoolCode, text ];
let query = `SELECT id, name FROM students WHERE school_code = ? AND name REGEXP ? `

Model.dataSource.connector.query(query, params, (err, res) => {} );
