Example 7 with ReadView

use of io.mycat.vertx.ReadView in project Mycat2 by MyCATApache.

the class PacketUtil method decodeOkPacketPayload.

// simplify the ok packet as those properties are actually not used for now
public static Packets.OkPacket decodeOkPacketPayload(Buffer payload) {
    ReadView readView = new ReadView(payload);
    readView.skipInReading(1);
    long affectedRows = readView.readLenencInt();
    long lastInsertId = readView.readLenencInt();
    int serverStatusFlags = readView.readLenencInt().intValue();
    String statusInfo = null;
    String sessionStateInfo = null;
    return new Packets.OkPacket(affectedRows, lastInsertId, serverStatusFlags, 0, statusInfo, sessionStateInfo);
}

Example 8 with ReadView

    // skip ERR packet header
    readView.skipInReading(1);
    int errorCode = (int) readView.readFixInt(2);
    // CLIENT_PROTOCOL_41 capability flag will always be set
    // SQL state marker will always be #

    String sqlState = readView.readFixString(5);
    String errorMessage = readView.readEOFString();
    return (new SQLException(errorMessage, sqlState, errorCode));
