note 69291 added to function.pdo-prepare

Attention using MySQL and prepared statements. Using a placeholder multiple times inside a statement doesn't work. PDO just translates the first occurance und leaves the second one as is. select id,name from demo_de where name LIKE :name OR name=:name You have to use select id,name from demo_de where name LIKE :name OR name=:name2 and bind name two times. I don't know if other databases (for example Oracle or MSSQL) support multiple occurances. If that's the fact, then the PDO behaviour for MySQL should be changed. ---- Server IP: 66.163.161.117 Probable Submitter: 84.173.146.220 ---- X-Spam-Status: No, hits=3.1 required=5.0 tests=DATE_MISSING,FROM_NO_LOWER autolearn=no version=2.64 ---- Manual Page -- http://www.php.net/manual/en/function.pdo-prepare.php Edit -- https://master.php.net/note/edit/69291 Del: integrated -- https://master.php.net/note/delete/69291/integrated Del: useless -- https://master.php.net/note/delete/69291/useless Del: bad code -- https://master.php.net/note/delete/69291/bad+code Del: spam -- https://master.php.net/note/delete/69291/spam Del: non-english -- https://master.php.net/note/delete/69291/non-english Del: in docs -- https://master.php.net/note/delete/69291/in+docs Del: other reasons-- https://master.php.net/note/delete/69291 Reject -- https://master.php.net/note/reject/69291 Search -- https://master.php.net/manage/user-notes.php
