PDOStatement::execute 值不适用于 WHERE 条件和 HAVING 条件

Question

我有一个错误的 PDOStatement::execute Values with WHERE Con​​dition & HAVING Condition in the same requette

我如何在 WHERE、HAVING 两个主题中执行准备值

$MyRequetteRecords = "
SELECT 
    _md_currencies._fd_currency,
    (
        SELECT GROUP_CONCAT( _md_tasks_level1._fd_name SEPARATOR ' + ') FROM _x_md_currencies_x_md_tasks
                
        LEFT JOIN 
            _md_tasks AS _md_tasks_level1 ON
            _x_md_currencies_x_md_tasks.ID_md_tasks = _md_tasks_level1.ID  
        
            WHERE _x_md_currencies_x_md_tasks.ID_md_currencies = _md_currencies.ID
    ) AS Many2Many_Currency

From 
    _md_currencies 
WHERE 
    _md_currencies._fd_currency  LIKE '% :value0 %' 
HAVING 
    Many2Many_Currency LIKE '% :value1 %'   
";


$ValueRequette=[
  'value0' => 'Currency 1',
  'value1' => 'Task' 
];


$statement = $bdd_dataManger->prepare($MyRequetteRecords); 
$statement->execute($ValueRequette);

$Record = $statement->fetchAll(\PDO::FETCH_ASSOC);
$statement->closeCursor();

错误： 参数号无效：绑定变量数与标记数不匹配

你的 mysql 代码首先会运行有问题，所以你总是应该测试你的查询

WHERE _x_md_currencies_x_md_tasks.ID_md_currencies = _md_currencies.ID),"") sho9uld 该行看起来像，因为列和表名用点分隔，ifnull 还需要一个参数，所以你需要先关闭一个括号

php部分的错误，首先是你使用单引号alreadx来确定字符串，所以在字符串内部使用它们是有问题的，因为你真的不需要它。

正如您在$ValueRequette=看到的那样，您必须使用带双点的palcehoders 名称

$MyRequetteRecords = '
     
        SELECT `_md_currencies`.`_fd_currency`,
                        IFNULL(
                                (SELECT GROUP_CONCAT( _md_tasks_level1._fd_name SEPARATOR ' + ') FROM _x_md_currencies_x_md_tasks
                                    
                            LEFT JOIN 
                                _md_tasks AS _md_tasks_level1 ON
                                _x_md_currencies_x_md_tasks.ID_md_tasks = _md_tasks_level1.ID  
                            
                                WHERE _x_md_currencies_x_md_tasks.ID_md_currencies = _md_currencies.ID),"") 
                             AS Many2Many_Currency

        From 
        `_md_currencies` 

        WHERE `_md_currencies`.`_fd_currency`  LIKE :value0  
        HAVING Many2Many_Currency LIKE :value1 

'


$ValueRequette=[
  ':value0' => '%' +'Currency 1'+'%' ,
  ':value1' => '%' +'Task'+'%'  
]
