MySQLStatement
class MySQLStatement extends Query (View source)
Provides a record-view for mysqli prepared statements
By default streams unbuffered data, but seek(), rewind(), or numRecords() will force the statement to buffer itself and sacrifice any potential performance benefit.
Properties
| protected deprecated | array | $currentRecord | The current record in the iterator. |
from Query |
| protected deprecated | int | $rowNum | The number of the current row in the iterator. |
from Query |
| protected deprecated | bool | $queryHasBegun | Flag to keep track of whether iteration has begun, to prevent unnecessary seeks |
from Query |
| protected | mysqli_stmt | $statement | The related mysqli statement object if generated using a prepared query |
|
| protected | mysqli_result | $metadata | Metadata result for this statement |
|
| protected | bool | $bound | Is the statement bound to the current resultset? |
|
| protected | array | $columns | List of column names |

Methods
Return an array containing all the values from a specific column. If no column is set, then the first will be returned
Return an array containing all values in the leftmost column, where the keys are the same as the values.
Iterator function implementation. Rewind the iterator to the first item and return it.
Iterator function implementation. Check if the iterator is pointing to a valid item.
Hook the result-set given into a Query class, suitable for use by SilverStripe.
