CollectionModify::bindBind value to query placeholder

说明

Bind a parameter to the placeholder in the search condition of the modify operation.

The placeholder has the form of :NAME where ':' is a common prefix that must always exists before any NAME where NAME is the name of the placeholder. The bind method accepts a list of placeholders if multiple entities have to be substituted in the search condition of the modify operation.

参数

placeholder_values

Placeholder values to substitute in the search condition. Multiple values are allowed and have to be passed as an array of mappings PLACEHOLDER_NAME->PLACEHOLDER_VALUE.

返回值

A CollectionModify object that can be used to execute the command, or to add additional operations.

范例

Example #1 mysql_xdevapi\CollectionModify::bind() example

<?php
$session 
mysql_xdevapi\getSession("mysqlx://user:password@localhost");
$session->sql("DROP DATABASE IF EXISTS addressbook")->execute();
$session->sql("CREATE DATABASE addressbook")->execute();

$schema     $session->getSchema("addressbook");
$collection $schema->createCollection("people");

$result $collection
  
->add(
  
'{"name":   "Bernie",
    "traits": ["Friend", "Brother", "Human"]}'

  ->
execute();

$collection
  
->modify("name = :name")
  ->
bind(['name' => 'Bernie'])
  ->
arrayAppend('traits''Happy')
  ->
execute();

$result $collection
  
->find()
  ->
execute();

print_r($result->fetchAll());
?>

以上例程的输出类似于:

Array
(
    [0] => Array
        (
            [_id] => 00005b6b53610000000000000110
            [name] => Bernie
            [traits] => Array
                (
                    [0] => Friend
                    [1] => Brother
                    [2] => Human
                    [3] => Happy
                )
        )
)
