/**
 * CDbExpression represents a DB expression that does not need escaping.
 * CDbExpression is mainly used in {@link CActiveRecord} as attribute values.
 * When inserting or updating a {@link CActiveRecord}, attribute values of
 * type CDbExpression will be directly put into the corresponding SQL statement
 * without escaping. A typical usage is that an attribute is set with 'NOW()'
 * expression so that saving the record would fill the corresponding column
 * with the current DB server timestamp.
 *
 * Starting from version 1.1.1, one can also specify parameters to be bound
 * for the expression. For example, if the expression is 'LOWER(:value)', then
 * one can set {@link params} to be <code>array(':value'=>$value)</code>.
