A statement decorator that implements buffered results.
This statement decorator will save fetched results in memory, allowing the iterator to be rewound and reused.
$_allFetched
protected boolean
$_count
protected integer
$_counter
protected integer
$_records
protected array
Returns the next row for the result set after executing this statement. Rows can be fetched to contain columns as names or positions. If no rows are left in result set, this method will return false.
__construct( Cake\Database\StatementInterface|null $statement null , Cake\Database\Driver|null $driver null )
Constructor
Cake\Database\StatementInterface
|null $statement
optional null Cake\Database\Driver
|null $driver
optional null Cake\Database\Statement\StatementDecorator::__construct()
execute( array|null $params null )
Execute the statement and return the results.
$params
optional null Cake\Database\Statement\StatementDecorator::execute()
fetch( string $type 'num' )
Returns the next row for the result set after executing this statement. Rows can be fetched to contain columns as names or positions. If no rows are left in result set, this method will return false.
$type
optional 'num' Cake\Database\Statement\StatementDecorator::fetch()
fetchAll( string $type 'num' )
Returns an array with all rows resulting from executing this statement.
$type
optional 'num' Cake\Database\Statement\StatementDecorator::fetchAll()
rowCount( )
Returns the number of rows affected by this SQL statement.
Cake\Database\Statement\StatementDecorator::rowCount()
__get( string $property )
Magic getter to return $queryString as read-only.
$property
bind( array $params , array $types )
Binds a set of values to statement object with corresponding type.
$params
$types
Cake\Database\StatementInterface::bind()
bindValue( string|integer $column , mixed $value , string $type 'string' )
Assign a value to a positional or named variable in prepared query. If using positional variables you need to start with index one, if using named params then just use the name in any order.
It is not allowed to combine positional and named variables in the same statement.
$statement->bindValue(1, 'a title'); $statement->bindValue('active', true, 'boolean'); $statement->bindValue(5, new \DateTime(), 'date');
$column
$value
$type
optional 'string' Cake\Database\StatementInterface::bindValue()
closeCursor( )
Closes a cursor in the database, freeing up any resources and memory allocated to it. In most cases you don't need to call this method, as it is automatically called after fetching all results from the result set.
Cake\Database\StatementInterface::closeCursor()
columnCount( )
Returns the number of columns this statement's results will contain.
$statement = $connection->prepare('SELECT id, title from articles'); $statement->execute(); echo $statement->columnCount(); // outputs 2
Cake\Database\StatementInterface::columnCount()
count( )
Statements can be passed as argument for count() to return the number for affected rows from last execution.
Cake\Database\StatementInterface::count()
errorCode( )
Returns the error code for the last error that occurred when executing this statement.
Cake\Database\StatementInterface::errorCode()
errorInfo( )
Returns the error information for the last error that occurred when executing this statement.
Cake\Database\StatementInterface::errorInfo()
getInnerStatement( )
Returns the statement object that was decorated by this class.
Cake\Database\StatementInterface
getIterator( )
Statements are iterable as arrays, this method will return the iterator object for traversing all items in the result.
$statement = $connection->prepare('SELECT id, title from articles'); foreach ($statement as $row) { //do stuff }
IteratorAggregate::getIterator()
lastInsertId( string|null $table null , string|null $column null )
Returns the latest primary inserted using this statement.
$table
optional null $column
optional null Cake\Database\StatementInterface::lastInsertId()
cast( mixed $value , Cake\Database\Type|string $type )
Converts a give value to a suitable database value based on type and return relevant internal statement type
$value
Cake\Database\Type
|string $type
matchTypes( array $columns , array $types )
Matches columns to corresponding types
Both $columns and $types should either be numeric based or string key based at the same time.
$columns
$types
