|---|---|---|---|
| $emulateExecution | whether to emulate the actual query execution, returning empty or false results. | ||
| $indexBy | string | callable | ||
| $limit | maximum number of records to be returned. If not set or less than 0, it means no limit. | ||
| $offset | zero-based offset from where the records are to be returned. If not set or less than 0, it means starting from the beginning. | ||
| $orderBy | how to sort the query results. This is used to construct the ORDER BY clause in a SQL statement. The array keys are the columns to be sorted by, and the array values are the corresponding sort directions which can be either SORT_ASC or SORT_DESC. The array may also contain [[Expression]] objects. If that is the case, the expressions will be converted into strings without any change. | ||
| $where | query condition. This refers to the WHERE clause in a SQL statement. For example, ['age' => 31, 'team' => 1]. |
| 메소드 | 설명 | |
|---|---|---|
| addOrderBy ( string | array | yii\db\Expression $columns ) | Adds additional ORDER BY columns to the query. | |
| andFilterWhere ( array $condition ) | Adds an additional WHERE condition to the existing one but ignores [[isEmpty()|empty operands]]. | |
| andWhere ( string | array $condition ) | Adds an additional WHERE condition to the existing one. | |
| emulateExecution ( boolean $value = true ) | Sets whether to emulate query execution, preventing any interaction with data storage. | |
| filterWhere ( array $condition ) | Sets the WHERE part of the query but ignores [[isEmpty()|empty operands]]. | |
| indexBy ( string | callable $column ) | Sets the [[indexBy]] property. | |
| limit ( integer $limit ) | Sets the LIMIT part of the query. | |
| offset ( integer $offset ) | Sets the OFFSET part of the query. | |
| orFilterWhere ( array $condition ) | Adds an additional WHERE condition to the existing one but ignores [[isEmpty()|empty operands]]. | |
| orWhere ( string | array $condition ) | Adds an additional WHERE condition to the existing one. | |
| orderBy ( string | array | yii\db\Expression $columns ) | Sets the ORDER BY part of the query. | |
| where ( string | array $condition ) | Sets the WHERE part of the query. |
| 메소드 | 설명 | |
|---|---|---|
| filterCondition ( array $condition ) : array | Removes [[isEmpty()|empty operands]] from the given query condition. | |
| isEmpty ( mixed $value ) : boolean | Returns a value indicating whether the give value is "empty". | |
| normalizeOrderBy ( array | string | yii\db\Expression $columns ) : array | Normalizes format of ORDER BY data |
| public addOrderBy ( string | array | yii\db\Expression $columns ) | ||
| $columns | string | array | yii\db\Expression | the columns (and the directions) to be ordered by. Columns can be specified in either a string (e.g. "id ASC, name DESC") or an array (e.g. `['id' => SORT_ASC, 'name' => SORT_DESC]`). The method will automatically quote the column names unless a column contains some parenthesis (which means the column contains a DB expression). Note that if your order-by is an expression containing commas, you should always use an array to represent the order-by information. Otherwise, the method will not be able to correctly determine the order-by columns. Since version 2.0.7, an [[Expression]] object can be passed to specify the ORDER BY part explicitly in plain SQL. |
| public andFilterWhere ( array $condition ) | ||
| $condition | array | the new WHERE condition. Please refer to [[where()]] on how to specify this parameter. |
| public emulateExecution ( boolean $value = true ) | ||
| $value | boolean | whether to prevent query execution. |
| protected filterCondition ( array $condition ) : array | ||
| $condition | array | the original condition |
| 리턴 | array | the condition with [[isEmpty()|empty operands]] removed. |
| public filterWhere ( array $condition ) | ||
| $condition | array | the conditions that should be put in the WHERE part. See [[where()]] on how to specify this parameter. |
| public indexBy ( string | callable $column ) | ||
| $column | string | callable | the name of the column by which the query results should be indexed by. This can also be a callable (e.g. anonymous function) that returns the index value based on the given row data. The signature of the callable should be: ```php function ($row) { // return the index value corresponding to $row } ``` |
| public orFilterWhere ( array $condition ) | ||
| $condition | array | the new WHERE condition. Please refer to [[where()]] on how to specify this parameter. |
| public orderBy ( string | array | yii\db\Expression $columns ) | ||
| $columns | string | array | yii\db\Expression | the columns (and the directions) to be ordered by. Columns can be specified in either a string (e.g. `"id ASC, name DESC"`) or an array (e.g. `['id' => SORT_ASC, 'name' => SORT_DESC]`). The method will automatically quote the column names unless a column contains some parenthesis (which means the column contains a DB expression). Note that if your order-by is an expression containing commas, you should always use an array to represent the order-by information. Otherwise, the method will not be able to correctly determine the order-by columns. Since version 2.0.7, an [[Expression]] object can be passed to specify the ORDER BY part explicitly in plain SQL. |
