我有以下选择查询:
SELECT `tbl_calendar`.`id_tech` count(`tbl_calendar`.`id_tech`) AS scheduled ,
(
SELECT `tbl_calendar`.`id_tech` ,
`tbl_client`.`c_name` AS name ,
count(`tbl_calendar`.`id_tech`) AS quantity
FROM `tbl_calendar`
LEFT JOIN `tbl_client`
ON (
`tbl_calendar`.`id_tech` = `tbl_client`.`id_client`)
LEFT JOIN `tbl_service_report`
ON (
`tbl_service_report`.`id_service_case` = `tbl_calendar`.`id_service_case`)
WHERE `tbl_service_report`.`timeout` !='')
FROM `db_pm`.`tbl_service_case`
INNER JOIN `db_pm`.`tbl_calendar`
ON (
`tbl_service_case`.`id_service_case` = `tbl_calendar`.`id_service_case`)
INNER JOIN `db_pm`.`tbl_service_report`
ON (
`tbl_service_case`.`id_service_case` = `tbl_service_report`.`id_service_case`) AS finished
GROUP BY `tbl_calendar`.`id_tech`
需要输出:
|----|-----------|----------|
| ID | Scheduled | Finished |
|----|-----------|----------|
| 1 | 2 | 1 |
|----|-----------|----------|
但结果是
操作数应包含1列
请帮忙
