/**
* Sets the WHERE part of the query.
*
* The method requires a $condition parameter, and optionally a $params parameter
* specifying the values to be bound to the query.
*
* The $condition parameter should be either a string (e.g. 'id=1') or an array.
* If the latter, it must be in one of the following two formats:
*
* - hash format: `array('column1' => value1, 'column2' => value2, ...)`
* - operator format: `array(operator, operand1, operand2, ...)`
*
* A condition in hash format represents the following SQL expression in general:
* `column1=value1 AND column2=value2 AND ...`. In case when a value is an array,
* an `IN` expression will be generated. And if a value is null, `IS NULL` will be used
* in the generated expression. Below are some examples:
*
* - `array('type' => 1, 'status' => 2)` generates `(type = 1) AND (status = 2)`.
* - `array('id' => array(1, 2, 3), 'status' => 2)` generates `(id IN (1, 2, 3)) AND (status = 2)`.
* - `array('status' => null) generates `status IS NULL`.
*
* A condition in operator format generates the SQL expression according to the specified operator, which
* can be one of the followings:
*
* - `and`: the operands should be concatenated together using `AND`. For example,
* `array('and', 'id=1', 'id=2')` will generate `id=1 AND id=2`. If an operand is an array,
* it will be converted into a string using the rules described here. For example,
* `array('and', 'type=1', array('or', 'id=1', 'id=2'))` will generate `type=1 AND (id=1 OR id=2)`.
* The method will NOT do any quoting or escaping.
*
* - `or`: similar to the `and` operator except that the operands are concatenated using `OR`.
*
* - `between`: operand 1 should be the column name, and operand 2 and 3 should be the
* starting and ending values of the range that the column is in.
* For example, `array('between', 'id', 1, 10)` will generate `id BETWEEN 1 AND 10`.
*
* - `not between`: similar to `between` except the `BETWEEN` is replaced with `NOT BETWEEN`
* in the generated condition.
*
* - `in`: operand 1 should be a column or DB expression, and operand 2 be an array representing
* the range of the values that the column or DB expression should be in. For example,
* `array('in', 'id', array(1, 2, 3))` will generate `id IN (1, 2, 3)`.
* The method will properly quote the column name and escape values in the range.
*
* - `not in`: similar to the `in` operator except that `IN` is replaced with `NOT IN` in the generated condition.
*
* - `like`: operand 1 should be a column or DB expression, and operand 2 be a string or an array representing
* the values that the column or DB expression should be like.
* For example, `array('like', 'name', '%tester%')` will generate `name LIKE '%tester%'`.
* When the value range is given as an array, multiple `LIKE` predicates will be generated and concatenated
* using `AND`. For example, `array('like', 'name', array('%test%', '%sample%'))` will generate
* `name LIKE '%test%' AND name LIKE '%sample%'`.
* The method will properly quote the column name and escape values in the range.
*
* - `or like`: similar to the `like` operator except that `OR` is used to concatenate the `LIKE`
* predicates when operand 2 is an array.
*
* - `not like`: similar to the `like` operator except that `LIKE` is replaced with `NOT LIKE`
* in the generated condition.
*
* - `or not like`: similar to the `not like` operator except that `OR` is used to concatenate
* the `NOT LIKE` predicates.

/**
* Sets the WHERE part of the query.
*
* The method requires a $condition parameter, and optionally a $params parameter
* specifying the values to be bound to the query.
*
* The $condition parameter should be either a string (e.g. 'id=1') or an array.
* If the latter, it must be in one of the following two formats:
*
* - hash format: `array('column1' => value1, 'column2' => value2, ...)`
* - operator format: `array(operator, operand1, operand2, ...)`
*
* A condition in hash format represents the following SQL expression in general:
* `column1=value1 AND column2=value2 AND ...`. In case when a value is an array,
* an `IN` expression will be generated. And if a value is null, `IS NULL` will be used
* in the generated expression. Below are some examples:
*
* - `array('type' => 1, 'status' => 2)` generates `(type = 1) AND (status = 2)`.
* - `array('id' => array(1, 2, 3), 'status' => 2)` generates `(id IN (1, 2, 3)) AND (status = 2)`.
* - `array('status' => null) generates `status IS NULL`.
*
* A condition in operator format generates the SQL expression according to the specified operator, which
* can be one of the followings:
*
* - `and`: the operands should be concatenated together using `AND`. For example,
* `array('and', 'id=1', 'id=2')` will generate `id=1 AND id=2`. If an operand is an array,
* it will be converted into a string using the rules described here. For example,
* `array('and', 'type=1', array('or', 'id=1', 'id=2'))` will generate `type=1 AND (id=1 OR id=2)`.
* The method will NOT do any quoting or escaping.
*
* - `or`: similar to the `and` operator except that the operands are concatenated using `OR`.
*
* - `between`: operand 1 should be the column name, and operand 2 and 3 should be the
* starting and ending values of the range that the column is in.
* For example, `array('between', 'id', 1, 10)` will generate `id BETWEEN 1 AND 10`.
*
* - `not between`: similar to `between` except the `BETWEEN` is replaced with `NOT BETWEEN`
* in the generated condition.
*
* - `in`: operand 1 should be a column or DB expression, and operand 2 be an array representing
* the range of the values that the column or DB expression should be in. For example,
* `array('in', 'id', array(1, 2, 3))` will generate `id IN (1, 2, 3)`.
* The method will properly quote the column name and escape values in the range.
*
* - `not in`: similar to the `in` operator except that `IN` is replaced with `NOT IN` in the generated condition.
*
* - `like`: operand 1 should be a column or DB expression, and operand 2 be a string or an array representing
* the values that the column or DB expression should be like.
* For example, `array('like', 'name', '%tester%')` will generate `name LIKE '%tester%'`.
* When the value range is given as an array, multiple `LIKE` predicates will be generated and concatenated
* using `AND`. For example, `array('like', 'name', array('%test%', '%sample%'))` will generate
* `name LIKE '%test%' AND name LIKE '%sample%'`.
* The method will properly quote the column name and escape values in the range.
*
* - `or like`: similar to the `like` operator except that `OR` is used to concatenate the `LIKE`
* predicates when operand 2 is an array.
*
* - `not like`: similar to the `like` operator except that `LIKE` is replaced with `NOT LIKE`
* in the generated condition.
*
* - `or not like`: similar to the `not like` operator except that `OR` is used to concatenate
* the `NOT LIKE` predicates.
