我有一個相當複雜的mysqli插入語句來做,因爲我需要從另外兩個表中收集數據,並且還可以在一個語句中使用一些可用於php的變量。高級MySQLi查詢語法

由於準備好的語句的變量順序,我感到困惑。 - 我只插入四個值,但爲了獲得t1和t2的值,我還在bind_param語句中引用了這三個附加變量。

我應該填充jobRoleID,companyID,DepartmentID的,competenceID與$ newJobRoleID,$ newCompanyID,t1.id,t2.id

$addJobCompetencies = $con->prepare(" 
INSERT INTO jobRoleCompetencies (jobRoleID,companyID,departmentID,competenceID) 
WITH t1 AS (SELECT id FROM departments WHERE companyID = ? AND department = ?), 
    t2 AS (SELECT id FROM competencies WHERE companyID = ?) 
    SELECT ?,?,t1.id,t2.id FROM t1,t2"); 

if($addJobCompetencies) { 
    $addJobCompetencies->bind_param('isiii', $newCompanyID,$row['department'],$newCompanyID,$newJobRoleID,$newCompanyID); 
    $addJobCompetencies->execute(); 
} else { 
    echo $con->error; 
} 
$addJobCompetencies->free_result(); 

我得到一個語法錯誤,但我不是100%確定爲什麼。誰能幫忙?

感謝 丹

我還沒有解決與此查詢的語法問題,但都圍繞它得到了通過簡單組合的選擇語句檢索我需要在一個SELECT語句的所有信息...

SELECT?,?,departments.id AS departmentID,competencies.id AS competencyID FROM departments,competencies ... etc
