我正在尝试使用LOAD XML LOCAL INFILE命令将文件（大小= 7.4GB）导入到mysql表中。我试图避免创建自己的表结构..

任何帮助，都会很棒!!

Answer 1

CREATE TABLE vehicles (
    time    DECIMAL(7,2) NOT NULL,
    id      VARCHAR(255) NOT NULL,
    x       DECIMAL(7,2),
    y       DECIMAL(7,2),
    angle   DECIMAL(5,2),
    type    VARCHAR(255),
    speed   DECIMAL(3,2),
    pos     DECIMAL(3,2),
    lane    VARCHAR(255),
    slope   DECIMAL(3,2),
    PRIMARY KEY(time, id)
);

LOAD XML LOCAL INFILE '/path/to/data.xml'
    INTO TABLE vehicles
    ROWS IDENTIFIED BY '<vehicle>';

LOAD XML LOCAL INFILE
