加载数据文件问题

Question

I'm currently using LOAD DATA INFILE in my query, but I am not sure how to separate the data

The data is in the following format firstname:lastname

$this->db->query("LOAD DATA INFILE 'names.txt' 
                  INTO names firstname lastname 
                FIELDS TERMINATED BY ':'");

How would I use this to take the data from the text file and split firstname:lastname to insert firstname into firstname & lastname into lastname?

Answer 1

I'm assuming your table name is names . In which case the query should be:

"LOAD DATA INFILE 'names.txt' 
    INTO TABLE names
    FIELDS TERMINATED BY ':' 
    (firstname, lastname)"

Then of course you have to execute the statement.

Also take care of newline characters, field enclosure characters and field escape characters, for which you specify [LINES] TERMINATED BY , [FIELDS] ENCLOSED BY and [FIELDS] ESCAPED BY respectively (square brackets meaning that you only specify LINES or FIELDS once).
