|
|
* - `['type' => 1, 'status' => 2]` generates `(type = 1) AND (status = 2)`.
|
|
|
|
* - `['id' => [1, 2, 3], 'status' => 2]` generates `(id IN (1, 2, 3)) AND (status = 2)`.
|
|
|
|
* - `['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,
|
|
|
|
* `['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,
|
|
|
|
* `['and', 'type=1', ['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, `['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,
|
|
|
|
* `['in', 'id', [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, `['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, `['like', 'name', ['%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.
