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

Question

我有一个 erreur PDOStatement::execute 值在同一请求中具有 WHERE 条件和 HAVING 条件

我如何在 WHERE、HAVING 这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： 参数编号无效：绑定变量的数量与标记的数量不匹配

您的 mysql 代码首先遇到问题运行，因此您应该始终测试您的查询

WHERE _x_md_currencies_x_md_tasks.ID_md_currencies = _md_currencies.ID),"") 该行应该看起来像，因为列和 table 名称由点分隔，ifnull 还需要一个参数，所以您需要先关闭一个 brakcket

php 部分的错误首先是您使用单引号 alreadx 来确定字符串，因此在字符串内部使用它们是有问题的，因为您确实不需要它。

如您所见$ValueRequette=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'+'%'  
]

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

PDOStatement::execute Values doesn't work with WHERE Condition & HAVING Condition

php

mysql

pdo

having
