您好!我有一個需要輸出屏幕數據的查詢。
每個屏幕有4個展位可供展示。我需要一個查詢有一個結果(因爲我只有一個屏幕),並有4個展位(怎麼我分配的4個展位)在選擇查詢中選擇MYSQL
這裏是我的查詢:
$result = DB::select("
SELECT
`A`.`scr_name`,
`A`.`mission_id`,
`B`.`booth_id`,
`E`.`name`
FROM `tbl_screen` `A`
LEFT JOIN
`tbl_screen_booths` `B`
ON `B`.`screen_id` = `A`.`id`
LEFT JOIN
`tbl_service_booths` `C`
ON `B`.`booth_id` = `C`.`id`
LEFT JOIN
`tbl_missions_services` `D`
ON `C`.`mission_services_id` = `D`.`id`
LEFT JOIN
`tbl_services` `E`
ON `D`.`service_id` = `E`.`id`
WHERE `A`.`mission_id` = $mission_id
GROUP BY
`B`.`booth_id`;
");
return $result;
我想是這樣這樣的:
"scr_name": "Test Screen",
"mission_id": 2,
"name": "booth1", //index[0]
"name": "booth2", //index[1]
"name": "booth3", //index[2]
"name": "booth4" //index[4]
我的查詢返回的是這樣的:
[
{
"scr_name": "Test Screen",
"mission_id": 2,
"booth_id": 7,
"name": "booth1"
},
{
"scr_name": "Test Screen",
"mission_id": 2,
"booth_id": 9,
"name": "booth2"
},
{
"scr_name": "Test Screen",
"mission_id": 2,
"booth_id": 10,
"name": "booth3"
},
{
"scr_name": "Test Screen",
"mission_id": 2,
"booth_id": 11,
"name": "booth4"
}
]
那會做訣竅,謝謝! –
但是這不適合,如果我有多個屏幕,因爲它會返回多個結果。 –
然後你需要迭代數據..把一些邏輯..然後產生輸出..這只是你的數據的示例 – ZeroOne
