error 1265. Data truncated for column when trying to load data from txt file

You're missing FIELDS TERMINATED BY ',' and it's assuming you're delimiting by tabs by default.

This error means that at least one row in your Pickup_withoutproxy2.txt file has a value in its first column that is larger than an int (your PickupId field).

An Int can only accept values between -2147483648 to 2147483647.

Review your data to see what's going on. You could try to load it into a temp table with a varchar data type if your txt file is extremely large and difficult to see. Easy enough to check for an int once loaded in the database.

Good luck.

I had this issue when trying to convert an existing varchar column to enum. For me the issue was that there were existing values for that column that were not part of the enum's list of accepted values. So if your enum will only allow values, say ('dog', 'cat') but there is a row with bird in your table, the MODIFY COLUMN will fail with this error.
