Beispiel #1 mysql_xdevapi\RowResult::getColumns() example
<?php
$session = mysql_xdevapi\getSession("mysqlx://user:password@localhost");
$session->sql("DROP DATABASE addressbook")->execute();
$session->sql("CREATE DATABASE foo")->execute();
$session->sql("CREATE TABLE foo.test_table(x int)")->execute();
$session->sql("INSERT INTO addressbook.names values ('John', 42), ('Sam', 33)")->execute();
$sql = $session->sql("SELECT * from addressbook.names")->execute();
$cols = $sql->getColumns();
print_r($cols);
Das oben gezeigte Beispiel erzeugt eine ähnliche Ausgabe wie:
Array ( [0] => mysql_xdevapi\FieldMetadata Object ( [type] => 7 [type_name] => BYTES [name] => name [original_name] => name [table] => names [original_table] => names [schema] => addressbook [catalog] => def [collation] => 255 [fractional_digits] => 0 [length] => 65535 [flags] => 0 [content_type] => 0 ) [1] => mysql_xdevapi\FieldMetadata Object ( [type] => 1 [type_name] => SINT [name] => age [original_name] => age [table] => names [original_table] => names [schema] => addressbook [catalog] => def [collation] => 0 [fractional_digits] => 0 [length] => 11 [flags] => 0 [content_type] => 0 ) )
