Question

每当我尝试为数据库测试端点时出现错误，它显示“代码”：“ER_PARSE_ERROR”

所以这是我的 mysql 数据库的 model：

let query = `UPDATE tbl_branch_info 
            SET 
            ${whats === undefined ? `` : `whats=${whats},`}
            ${twitter === undefined ? `` : `twitter='${twitter}',`}
            ${facebook === undefined ? `` : `facebook='${facebook}',`}
            ${snapchat === undefined ? `` : `snapchat='${snapchat}',`}
            ${instagram === undefined ? `` : `instagram='${instagram}',`}
            ${phone === undefined ? `` : `telephone=${phone},`}
            ${address === undefined ? `` : `address='${address}',`}
            ${email === undefined ? `` : `email='${email}',`}
            ${city_id === undefined ? `` : `city_id=${city_id},`}
            ${category_id === undefined ? `` : `category_id=${category_id},`}
            ${subCategoryId === undefined ? `` : `sub_cat_id=${subCategoryId},`}
            ${lon === undefined ? `` : `lon=${lon},`}
            ${lat === undefined ? `` : `lat=${lat}`}     
            WHERE branch_id = ${branch_id}`;

它给了我这个错误：

来自 postman 的错误消息

但是如果我改变了分支id之前的最后一行，这是lat到这个

lat='${lat}'

它会很好地传递数据，那么这里可能是什么问题？
