在数据中执行这条sql语句是没问题的

SELECT
	ANY_VALUE ( t1.id ) AS id,
	ANY_VALUE ( GROUP_CONCAT( CONCAT_WS( '-', t3.specification_id, t3.specification_value ) ) ) AS ids,
	ANY_VALUE ( GROUP_CONCAT( CONCAT_WS( '-', t4.name, t3.specification_value ) ) ) AS specification,
	ANY_VALUE ( GROUP_CONCAT( t2.goods_specification_value_id ) ) AS goods_specification_value_id 
FROM
	t_product t1
	LEFT JOIN t_product_specification t2 ON t1.id = t2.product_id
	LEFT JOIN t_goods_specification_value t3 ON t2.goods_specification_value_id = t3.id
	LEFT JOIN t_dictionary t4 ON t3.specification_id = t4.id 
WHERE
	t1.goods_id = 5 
GROUP BY
	t1.id

但是拷贝到代码中执行就报错了，一直找不到原因

	let productResult = await this.app.mysql.query('SELECT ANY_VALUE (t1.id) AS id,ANY_VALUE (GROUP_CONCAT(CONCAT_WS('-',t3.specification_id,t3.specification_value))) AS ids,ANY_VALUE (GROUP_CONCAT(CONCAT_WS('-',t4.name,t3.specification_value))) AS specification,ANY_VALUE (GROUP_CONCAT(t2.goods_specification_value_id)) AS goods_specification_value_id FROM t_product t1 LEFT JOIN t_product_specification t2 ON t1.id=t2.product_id LEFT JOIN t_goods_specification_value t3 ON t2.goods_specification_value_id=t3.id LEFT JOIN t_dictionary t4 ON t3.specification_id=t4.id WHERE t1.goods_id=5 GROUP BY t1.id');
    let productData = this.ctx.camelize(productResult);
    for (let x in productData) {
      let tempData = productData[x].specification.split(',');
      for (let y in tempData) {
        productData[x][tempData[y].split('-')[0]] = tempData[y].split('-')[1]
      }
    }

最后定位到这个字符串处理函数CONCAT_WS，用了这个函数就会报错
