支持的数据类型 | Supported types

• UInt8, UInt16, UInt32, UInt64, Int8, Int16, Int32, Int64
• Float32, Float64
• Decimal(P, S), Decimal32(S), Decimal64(S), Decimal128(S)
• String
• Nothing
• FixedString(N)
• UUID
• Date
• Datetime
• Datetime64
• Nullable(T)
• IPv4
• IPv6
• Array(T)
• SimpleAggregateFunction(F, T)
• Tuple(T)
• Enum (can use LowCardinality instead)

Array of client options

It is also possible to create the client with configuration options:

use OneCk\Client;

$client = new Client(
    'tcp://localhost:9000',
    'username',
    'password',
    'database',
    [
        'connect_timeout' => 3,
        'socket_timeout'  => 30,
        'tcp_nodelay'     => true,
        'persistent'      => true,
    ]
);

The following options are available:

Name	Type	Default	Description
connect_timeout	float	3.0	The number of seconds that the client waits for a connect to a ClickHouse server before throwing a CkException exception.
socket_timeout	float	30.0	The number of seconds that the client waits for a respond from a ClickHouse server before throwing a CkException exception.
tcp_nodelay	boolean	false	Whether the Nagle algorithm is disabled on a TCP connection.
persistent	boolean	false	Whether to use a persistent connection.
