问题 I'm using createCommand in Yii Framework and I want to know about use bindValue for the params, Ex: Yii::app()->db->createCommand() ->update('table', array( 'field'=>'$valuefield', ), 'id_table=:id_table', array(':id_table'=>$id_table)); In this case, the value of $valuefield and $id_table are protected? Or I should create the sql query manually and pass the parameters with bindValue? Thank you! 回答1: In this case, the value of $valuefield and $id_table are protected? Yes. Method update

Confusion between bindValue() and bindParam()?

问题 I am confuse between these two functions Bindvalue() and BindParam() I read on php.net it does not escape % and _ , so be careful when using LIKE . So i think BindValue() is not used when we are using LIKE query. when we using LIKE query BindParam() is used. Because as i know BindParam can escape these % and _ . BindValue() doesn't gives protection against sql injection. I am not sure about this, is it true? friends tell what i mention in these 3 points is right or wrong. i am beginner in PDO

问题 So far I have been using PDO->bindParam however while reading the manual I found PDO->bindValue from what I can tell PDO->bindValue passes by value where as PDO->bindParam passes by reference, is this the only difference? $modThread = db()->prepare("UPDATE `threads` SET `modtime` = UNIX_TIMESTAMP( ) WHERE `threadid` =:id LIMIT 1"); while(something) { $modThread->bindParam(':id', $thread); $modThread->execute(); //*******************HERE********************// } Again while reading the manual I

How define the variable type in PDOStatement::bindValue()?

问题 The PDOStatement::bindValue() method offers a way to specify the type of the variable bound: PDOStatement::bindValue ( $parameter , $value [, $data_type = PDO::PARAM_STR ] ) I'm wondering, what's the purpose of specifying the data type, whereas when leaved as default ( PARAM_STR ) eventually the database will anyway cast the value to the proper type before using it? For example, if you have these queries over an INTEGER field: INSERT INTO table (integerField) VALUES (?) ; SELECT * FROM table

What is the correct solution for this? I also thought adding the % in the bindValue(:firstname, $firstname%) but i need to use the :firstname in other places too that should not have the %..
