Installation

composer require jetea/database=~2.0 -vvv

Usage

get connection

• MySql

$dsn = sprintf('mysql:host=%s;port=%s;dbname=%s;charset=%s', '127.0.0.1', 3306, 'es_demo', 'utf8mb4');
$conn = new MySqlConnection($dsn, 'root', 123123);

• Postgres

$dsn = sprintf('pgsql:host=%s;port=%s;dbname=%s', '127.0.0.1', 3306, 'es_demo');
$conn = new PostgresConnection($dsn, 'root', 123123);

insert and get insert id

$insertId = $conn->table('profile')->insertGetId([
    'name'      => 'test-name',
    'gender'    => 1,
    'birthday'  => '1988-12-01 01:00:01', //DATETIME
    'memo'      => 'this is a test memo',
    'lat'       => '30.54916000', //DECIMAL(10,8)
    'lng'       => '104.06761000' //DECIMAL(11,8)
]);

insert and get the number of rows affected

$affectNum = $conn->table('profile')->insert([
    [
        'name'      => 'test-name',
        'gender'    => 1,
        'birthday'  => '1988-12-01 01:00:01',
        'memo'      => 'this is a test memo',
        'lat'       => '30.54916000',
        'lng'       => '104.06761000'
    ],
    [
        'name'      => 'test-name-1',
        'gender'    => 1,
        'birthday'  => '2010-12-01 01:00:01',
        'memo'      => 'this is another test memo',
        'lat'       => '30.54916000',
        'lng'       => '104.06761000'
    ],
]);

update and get the number of rows affected

affectNum = $conn->update('update profile set name = :name, memo = :memo where id = :id', [
    ':name'     => 'test-name',
    ':memo'     => 'this is another memo',
    ':id'       => $id,
]);

select

$records = $conn->select('select * from profile where id = :id', [
    ':id'   => $id,
]);

delete and get the number of rows affected

$affectNum = $conn->delete('delete from profile where id = :id', [
    ':id'       => $id,
]);

transaction

$conn->transaction(function ($conn) {
    //do something...
});

get query logs

$queryLogs = $conn->getQueryLog();

execute the given callback in "dry run"(空转) mode

$conn->pretend(function ($conn) {
    //do something...
});
