是的CDbcriteria。？

Question

How to write the following query using CDBcriteria, I am trying to show my data in grid view using cdbcriteria.Is there any other way to show data in cgridview without using CDBcriteria.

SELECT * 
FROM  `user` 
WHERE role =  'employer'

I have tried like below:

$criteria = new CDbCriteria;

$criteria->condition = 'role=employer';
return new CActiveDataProvider('manageemployers', array(
'criteria'=>$criteria,

But its showing error

Answer 1

There is a few options, for example:

$criteria->compare('role', 'employer');

Or

$criteria->condition = 'role= :employer';
$criteria->params = ['employer'=>"employer"];

Your mistake was role="employer" - you forgot "". So you can also use this:

$criteria->condition = 'role = "employer"';

Answer 2

you can do that better way like

$model = Model::model()->findAll(array(
  'condition' => 'column_a = :name',
  'params'    => array(':name' => $someText)
));
