+/**
+ * TDbExpression represents a DB expression that does not need escaping.
+ * TDbExpression is mainly used in {@link CActiveRecord} as attribute values.
+ * When inserting or updating a {@link CActiveRecord}, attribute values of
+ * type TDbExpression 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.
