Exemplos

Exemplo #1 mysql_xdevapi\Schema::createCollection() example

<?php
$session
= mysql_xdevapi\getSession("mysqlx://user:password@localhost");

$session->sql("DROP DATABASE IF EXISTS food")->execute();
$session->sql("CREATE DATABASE food")->execute();
$session->sql("CREATE TABLE food.fruit(name text, rating text)")->execute();

$schema = $session->getSchema("food");
$schema->createCollection("trees");

print_r($schema->gettables());
print_r($schema->getcollections());

O exemplo acima produzirá algo semelhante a:

Array
(
    [fruit] => mysql_xdevapi\Table Object
        (
            [name] => fruit
        )
)
Array
(
    [trees] => mysql_xdevapi\Collection Object
        (
            [name] => trees
        )
)

Exemplo #2 mysql_xdevapi\Schema::createCollection() example

<?php
$collection
= $schema->createCollection("mycollection", '{
"validation": {
"level": "strict",
"schema": {
"id": "http://json-schema.org/geo",
"description": "A geographical coordinate",
"type": "object",
"properties": {
"latitude": {
"type": "number"
},
"longitude": {
"type": "number"
}
},
"required": ["latitude", "longitude"]
}
}
}'
);
// Succeeds
$collection->add('{"latitude": 10, "longitude": 20}')->execute();

// Fails, invalid types (not numbers)
$collection->add('{"latitude": "lat", "longitude": "long"}')->execute();
