Moved a few definitions from php_pdo_int.h to a new php_pdo_error.h
header file that can be included if drivers need PDO's own error
handling to be triggered within custom methods (e.g. PDO::pgsqlLOBOpen).

. Fix iterator based access
. Add new attribute ATTR_DEFAULT_FETCH_MODE: $bdh->setAttribute()
. Add new fetch mode: FETCH_PROPS_LATE, this fills object member
variables after calling the constructor (fixes #36428).

- Fix handling of read only property 'queryString'
- Fix overloading
- Move class init code to their defining .c files for simplification
- Mark class PDORow as final until there's a need to inherit this and
someone implements the handlers correct then.

fix my favourite typo.
fix compile warnings
|
|
|
|
|
|
|

- Verify fetch modes
- Add last fetch mode PDO_FETCH_FUNC (only valid inside fetchAll()) that
allows to completley customize the way data is treated on the fly

Allow drivers to add methods to dbh and stmt objects
(note that we can't use a class, because the use only sees the PDO class).
Clarify the api slightly:
PDO::exec() is used for one-shot queries that don't return rows
PDO::query() is a convenience function for returning a rowset without
having to go through the steps of preparing and executing.

PDOStatement::setFetchMode()
reset default fetch() mode for a statement to PDO_FETCH_BOTH
PDOStatement::setFetchMode(PDO_FETCH_NUM)
PDOStatement::setFetchMode(PDO_FETCH_ASSOC)
PDOStatement::setFetchMode(PDO_FETCH_BOTH)
PDOStatement::setFetchMode(PDO_FETCH_OBJ)
set default fetch() mode for a statement.
PDOStatement::setFetchMode(PDO_FETCH_COLUMN, int colno)
set default fetch() mode to retrieve colno-th column on each fetch() call.
PDOStatement::setFetchMode(PDO_FETCH_CLASS, string classname [, array ctor args])
set default fetch() mode to create an instance of classname,
calling it's ctor, passing the optional ctor args.
The names of the columns in the result set will be used as property names on
the object instance. PPP rules apply.
[NOTE: calling ctor is not yet implemented]
[TODO: this might crash PHP for persistent PDO handles]
PDOStatement::setFetchMode(PDO_FETCH_INTO, object obj)
Similar to PDO_FETCH_CLASS, except that each iteration will update the
supplied object properties.
[TODO: this might crash PHP for persistent PDO handles]
The default fetch() mode is used when no parameters are passed to
PDOStatement::fetch(). When using a statement in an iterator context,
PDOStatement::fetch() is called implicitly on each iteration.
object PDO::queryAndIterate(string sql, <PDOStatement::setFetchMode args>)
This is semantically equivalent to:
$stmt = $pdo->prepare($sql);
$stmt->execute();
$stmt->setFetchMode($args);
return $stmt;
Example/Intended usage:
/* fetch an array with numeric and string keys */
foreach ($pdo->queryAndIterate("select NAME, VALUE from test") as $row) {
debug_zval_dump($row);
}
/* fetch the value of column 1 into $row on each iteration */
foreach ($pdo->queryAndIterate("select NAME, VALUE from test",
PDO_FETCH_COLUMN, 1) as $row) {
debug_zval_dump($row); // string(3) "foo"
}
/* create a new instance of class Foo on each iteration */
foreach ($pdo->queryAndIterate("select NAME, VALUE from test",
PDO_FETCH_CLASS, 'Foo') as $row) {
debug_zval_dump($row);
/*
Object(Foo)#4 (2) refcount(2){
["NAME"]=>
string(12) "foo220051429" refcount(2)
["VALUE"]=>
string(12) "bar789825748" refcount(2)
}
*/
}
etc.
