Question

Я имею файл XML как

Я пытаюсь использовать команду LOAD XML LOCAL INFILE импортировать файл (размер = 7.4GB) в таблицу MySQL. Я стараюсь избегать создания структуры таблицы.

Любая помощь, было бы здорово !!

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>';
