計數和左連接不工作的權利

試圖做一個計數這些線路上的計數（engineerName）AS engineerCount，計數（managerName）作爲managerCount，計數（isContractor）作爲contractorCount 但它一直返回都是一樣的號碼三。所以我試圖添加一個Where爲每個，示例計數（isContractor，其中isContractor ='是'）作爲contractorCount但獲取錯誤請幫助，謝謝。計數和左連接不工作的權利

如果你的問題是關於SQL的，你可以編輯它來刪除所有的PHP噪聲，並用表格模式，一些示例數據和你試圖獲得的輸出替換它。您也可以比「獲取錯誤」更具體，因爲我們無法從這裏看到您的屏幕，也不知道「錯誤」的含義。試圖幫助你會更有用，並且可能會讓你更快得到答案。 –

SELECT 
    market, 
    areaName, 
    COUNT(engineerName) AS engineerCount, 
    Count(managerName) as managerCount, 
    Count(isContractor) as contractorCount 
FROM 
    employee.employees 
GROUP BY market

應該

Group By market,areaName在猜測。

這就是你所能看到的，因爲你沒有提供有用的信息。
