Property Details
Map of query condition to builder methods. These methods are used by buildCondition() to build SQL conditions from array syntax.
Mapping from abstract column types (keys) to physical column types (values).
Method Details
Builds a SQL statement for changing the definition of a column.
string alterColumn( $table, $column, $type ) | ||
$table | string | The table whose column is to be changed. The table name will be properly quoted by the method. |
$column | string | The name of the column to be changed. The name will be properly quoted by the method. |
$type | string | The new column type. The getColumnType() method will be invoked to convert abstract
column type (if any) into the physical one. Anything that is not recognized as abstract type will be kept
in the generated SQL. For example, 'string' will be turned into 'varchar(255)', while 'string not null'
will become 'varchar(255) not null'. You can also use PostgreSQL-specific syntax such as |
return | string | The SQL statement for changing the definition of a column. |
---|
Generates a batch INSERT SQL statement.
For example,
$sql = $queryBuilder->batchInsert('user', ['name', 'age'], [
['Tom', 30],
['Jane', 20],
['Linda', 25],
]);
Note that the values in each row must match the corresponding column names.
The method will properly escape the column names, and quote the values to be inserted.
string batchInsert( $table, $columns, $rows ) | ||
$table | string | The table that new rows will be inserted into. |
$columns | array | The column names |
$rows | array | The rows to be batch inserted into the table |
return | string | The batch INSERT SQL statement |
---|
Builds a SQL statement for enabling or disabling integrity check.
string checkIntegrity( $check = true, $schema = '', $table = '' ) | ||
$check | boolean | Whether to turn on or off the integrity check. |
$schema | string | The schema of the tables. |
$table | string | The table name. |
return | string | The SQL statement for checking integrity |
---|
Builds a SQL statement for dropping an index.
string dropIndex( $name, $table ) | ||
$name | string | The name of the index to be dropped. The name will be properly quoted by the method. |
$table | string | The table whose index is to be dropped. The name will be properly quoted by the method. |
return | string | The SQL statement for dropping an index. |
---|
Builds a SQL statement for renaming a DB table.
string renameTable( $oldName, $newName ) | ||
$oldName | string | The table to be renamed. The name will be properly quoted by the method. |
$newName | string | The new table name. The name will be properly quoted by the method. |
return | string | The SQL statement for renaming a DB table. |
---|
Creates a SQL statement for resetting the sequence value of a table's primary key.
The sequence will be reset such that the primary key of the next new row inserted will have the specified value or 1.
string resetSequence( $tableName, $value = null ) | ||
$tableName | string | The name of the table whose primary key sequence will be reset |
$value | mixed | The value for the primary key of the next new row inserted. If this is not set, the next new row's primary key will have a value 1. |
return | string | The SQL statement for resetting sequence |
---|---|---|
throws | yii\base\InvalidParamException | if the table does not exist or there is no sequence associated with the table. |
