Class CallbackStatement

__construct()source public

__construct( Cake\Database\StatementInterface $statement , Cake\Database\Driver $driver , callable $callback )

Constructor

Parameters

Cake\Database\StatementInterface $statement

The statement to decorate.

Cake\Database\Driver $driver

The driver instance used by the statement.

callable $callback

The callback to apply to results before they are returned.

Overrides

Cake\Database\Statement\StatementDecorator::__construct()

fetch()source public

fetch( string $type 'num' )

Fetch a row from the statement.

The result will be processed by the callback when it is not false.

Parameters

string $type optional 'num'

Either 'num' or 'assoc' to indicate the result format you would like.

Returns

array|false

Overrides

Cake\Database\Statement\StatementDecorator::fetch()

fetchAll()source public

fetchAll( string $type 'num' )

Fetch all rows from the statement.

Each row in the result will be processed by the callback when it is not `false.

Parameters

string $type optional 'num'

Either 'num' or 'assoc' to indicate the result format you would like.

Returns

array

Overrides

Cake\Database\Statement\StatementDecorator::fetchAll()

__get()source public

__get( string $property )

Magic getter to return $queryString as read-only.

Parameters

string $property

internal property to get

Returns

mixed

bind()source public

bind( array $params , array $types )

Binds a set of values to statement object with corresponding type.

Parameters

array $params

list of values to be bound

array $types

list of types to be used, keys should match those in $params

Implementation of

Cake\Database\StatementInterface::bind()

bindValue()source public

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.

Examples:

$statement->bindValue(1, 'a title');
$statement->bindValue('active', true, 'boolean');
$statement->bindValue(5, new \DateTime(), 'date');

Parameters

string|integer $column

name or param position to be bound

mixed $value

The value to bind to variable in query

string $type optional 'string'

name of configured Type class

Implementation of

Cake\Database\StatementInterface::bindValue()

closeCursor()source public

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.

Implementation of

Cake\Database\StatementInterface::closeCursor()

columnCount()source public

columnCount( )

Returns the number of columns this statement's results will contain.

Example:

$statement = $connection->prepare('SELECT id, title from articles');
$statement->execute();
echo $statement->columnCount(); // outputs 2

Returns

integer

Implementation of

Cake\Database\StatementInterface::columnCount()

count()source public

count( )

Statements can be passed as argument for count() to return the number for affected rows from last execution.

Returns

integer

Implementation of

Cake\Database\StatementInterface::count()

errorCode()source public

errorCode( )

Returns the error code for the last error that occurred when executing this statement.

Returns

integer|string

Implementation of

Cake\Database\StatementInterface::errorCode()

errorInfo()source public

errorInfo( )

Returns the error information for the last error that occurred when executing this statement.

Returns

array

Implementation of

Cake\Database\StatementInterface::errorInfo()

execute()source public

execute( array|null $params null )

Executes the statement by sending the SQL query to the database. It can optionally take an array or arguments to be bound to the query variables. Please note that binding parameters from this method will not perform any custom type conversion as it would normally happen when calling bindValue.

Parameters

array|null $params optional null

list of values to be bound to query

Returns

boolean
true on success, false otherwise

Implementation of

Cake\Database\StatementInterface::execute()

getInnerStatement()source public

getInnerStatement( )

Returns the statement object that was decorated by this class.

Returns

Cake\Database\StatementInterface

getIterator()source public

getIterator( )

Statements are iterable as arrays, this method will return the iterator object for traversing all items in the result.

Example:

$statement = $connection->prepare('SELECT id, title from articles');
foreach ($statement as $row) {
  //do stuff
}

Returns

Iterator

Implementation of

IteratorAggregate::getIterator()

lastInsertId()source public

lastInsertId( string|null $table null , string|null $column null )

Returns the latest primary inserted using this statement.

Parameters

string|null $table optional null

table name or sequence to get last insert value from

string|null $column optional null

the name of the column representing the primary key

Returns

string

Implementation of

Cake\Database\StatementInterface::lastInsertId()

rowCount()source public

rowCount( )

Returns the number of rows affected by this SQL statement.

Example:

$statement = $connection->prepare('SELECT id, title from articles');
$statement->execute();
print_r($statement->rowCount()); // will show 1

Returns

integer

Implementation of

Cake\Database\StatementInterface::rowCount()

cast()source public
