Cannot insert Integer data into MySQL, it inserts as a 0

907 views php


I have a module on my site that allows the user to import .txt files (with data separated by semicolons and escaped by newlines) which then I grab and do a LOAD DATA LOCAL INFILE with to insert on the database. The script works, but not as intended. Possible points of interest:

  • Text file is encoded as UTF-16LE
  • Database/table default charset is utf8, InnoDB engine.

The issue:

The script only inserts the correct data when all columns on the database are set to VARCHAR. If I try to change the ones that are meant to contain numbers to INT, the script inserts a 0 (zero) where the data should be.

Debug attempts:

Have tried inserting random hardcoded data on the script and it does work. This led me to believe the issue laid on file encoding.

I've tried manipulating the text file's encoding but that doesn't seem to help though.

Have also tried converting the file to .csv, .xlsx (using a different script with PhpSpreadsheet) but it yields the same results.

answered question

int(11) is useless, its just the same to int

Didn't know about that, thank you for pointing it out!

when you omit ENCLOSED BY '"' then all fields are enclosed and treated as strings.
