Normal developer would load the file using a programming language, do the parsing and insert into the table. However, for me, I thought I would do it using MySQL DATA LOAD, it is faster and yet, no programming language required to load the files.

I am posting a sample code on how to parse files line by line using MySQL.

LOAD DATA LOCAL INFILE ‘path/to/my/file’ into table [table-name]
(@line)
set field1 = SUBSTR(@line,1,10),
field2 = SUBSTR(@line, 11,12),
field3 = SUBSTR(@line, 48,19)

Now, what I did, is I just parsed text, since the file was not delimited but it had fixed width.

LOAD DATA LOCAL INFILE ‘/path/to/file/name’ INTO TABLE `tablename` FIELDS TERMINATED BY ‘,’ LINES TERMINATED BY ‘\n’;

Keeping in mind that the delimited used here is , so FIELDS TEMINATED BY ‘,’

You can change the delimiter to any thing your data have.
