/** |
||||
* Sets the WHERE part of the query. |
||||
* |
||||
* The method requires a $condition parameter. |
||||
* |
||||
* The $condition parameter should be an array in one of the following two formats: |
||||
* |
||||
* - hash format: `['column1' => value1, 'column2' => value2, ...]` |
||||
* - operator format: `[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: |
||||
* |
||||
* - `['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. |
