这是我的疑问：
SELECT
`inv_lc_details`.`lc_date`, `inv_lc_details`.`lc_no`,
`inv_lc_details`.`lc_amount`,
`inv_proforma_invoice`.`pi_no`, `inv_proforma_invoice_sub`.`pi_goods_des`,
`inv_proforma_invoice_sub`.`pi_amount`,
(SELECT `inv_lc_amend`.`lc_total_amount` FROM `inv_lc_amend` WHERE `inv_lc_amend`.`lc_no` = `inv_lc_details`.`lc_no`) AS lc_amend_amount,
(SELECT supplier_name FROM inv_supplier_details WHERE inv_supplier_details.supplier_id = `inv_proforma_invoice`.`supplier_id`) AS supplier_name,
(SELECT `inv_commercial_invoice`.`com_invoice_no` FROM `inv_commercial_invoice` WHERE `inv_commercial_invoice`.`lc_no` = `inv_lc_details`.`lc_no`)AS COM_NO,
(SELECT `inv_commercial_invoice`.`inv_receive_date` FROM `inv_commercial_invoice` WHERE `inv_commercial_invoice`.`lc_no` = `inv_lc_details`.`lc_no`)AS RCV_DATE,
(SELECT `inv_commercial_invoice_sub`.`no_kind` FROM `inv_commercial_invoice`, `inv_commercial_invoice_sub` WHERE `inv_commercial_invoice`.`com_invoice_no` = `inv_commercial_invoice_sub`.`com_invoice_no`) AS NO_KIND
FROM `inv_lc_details`,`inv_proforma_invoice`, `inv_proforma_invoice_sub`
WHERE
`inv_lc_details`.`lc_no` = `inv_proforma_invoice`.`lc_no`
AND `inv_proforma_invoice`.`pi_no` = `inv_proforma_invoice_sub`.`pi_no`
AND `inv_lc_details`.`lc_no` = 'lc01'
当我运行此查询时，会生成以下错误消息：
子查询返回超过1行。
问题是什么？如何解决？
