为什么下面的语法在PHP 5.4中运行而在PHP 5.2中不运行?
$stmt = $this->pdo->prepare('SELECT *, COALESCE(( 6371 * acos( cos( radians(:lat_params) ) *
cos( radians( tbl_restaurants_restaurants.lat ) ) *
cos( radians( tbl_restaurants_restaurants.lon ) - radians(:lon_params) ) +
sin( radians(:lat_params1) ) *
sin( radians( tbl_restaurants_restaurants.lat ) ) ) ), 0) AS
distance FROM
tbl_restaurants_restaurants WHERE tbl_restaurants_restaurants.is_deleted = 0
ORDER BY distance ASC LIMIT 0, :max');
$stmt->execute( array('lat_params' => $lat, 'lon_params' => $lon, 'lat_params1' => $lat, 'max' => $max ));
return $stmt;
由于PHP 5.2的兼容性,我遇到了错误。在PHP 5.4中,此脚本正常工作。
此link会再现相同的错误。
致命错误:未捕获的异常' PDOException'与消息 ' SQLSTATE [42000]: 语法错误或访问冲突:1064 SQL语法中有错误; 查看与您的MySQL服务器版本对应的手册,以获得在' 20'''''''''' 在第10行'在D:... \ ControllerRest.php:56 堆栈跟踪:#0 D:... \ ControllerRest.php(56): PDOStatement-> execute(Array)#1 D:... \ get_data.php(42): ControllerRest-> getRestaurantsNearbyResultsAtCount(' -20.290190',' -40.293366',' 20') #2 {main}抛出D:...... \ ControllerRest.php第56行
在PHP 5.2上运行此脚本是否有其他替代方法?
== UPDATE ==
shivanshu patel的答案确实有效!但现在该错误是由以下SQL语句生成的:
$stmt = $this->pdo->prepare("SELECT COALESCE(( 6371 * acos( cos( radians(:lat_params) ) * cos( radians( 'tbl_restaurants_restaurants'.'lat' ) ) * cos( radians( 'tbl_restaurants_restaurants'.'lon' ) - radians(:lon_params) ) + sin( radians(:lat_params1) ) * sin( radians( 'tbl_restaurants_restaurants'.'lat' ) ) ) ), 0) AS distance FROM 'tbl_restaurants_restaurants' ORDER BY distance DESC LIMIT 0, :default_to_find_distance");
$stmt->execute( array('lat_params' => $lat, 'lon_params' => $lon, 'lat_params1' => $lat, 'default_to_find_distance' => $default_to_find_distance) );
答案 0 :(得分:1)
尝试用``覆盖列和表,并确保max在int。
<?php
$stmt = $this->pdo->prepare('SELECT *, COALESCE(( 6371 * acos( cos( radians(:lat_params) ) *
cos( radians( `tbl_restaurants_restaurants`.`lat` ) ) *
cos( radians( `tbl_restaurants_restaurants`.`lon` ) - radians(:lon_params) ) +
sin( radians(:lat_params1) ) *
sin( radians( `tbl_restaurants_restaurants`.`lat` ) ) ) ), 0) AS
distance FROM
`tbl_restaurants_restaurants` WHERE `tbl_restaurants_restaurants`.`is_deleted` = 0
ORDER BY distance ASC LIMIT 0, :max');
$stmt->bindValue(':max', $max, PDO::PARAM_INT);
$stmt->execute( array('lat_params' => $lat, 'lon_params' => $lon, 'lat_params1' => $lat ));
return $stmt;
