MySQL LOAD DATA LOCAL date as first column returns '0000-00-00 00:00:00' for first row-CodePudding

when using LOAD DATA LOCAL and having a date in the first column then it always stores '0000-00-00 00:00:00' for only the very first row.

When placing a string column as very first column instead everything works fine. See cases A and B:

A) this first two rows in csv:

2022-01-31,hello_world
2022-01-31,hello_stackover

lead to this data in the mysql table:

0000-00-00 00:00;00,hello_world
2022-01-31 00:00:00,hello_stackover

B) this first two rows in csv:

hello_world,2022-01-31
hello_stackover,2022-01-31

lead to this data in the mysql table:

hello_world,2022-01-31 00:00:00
hello_stackover,2022-01-31 00:00:00

This is my sql:

LOAD DATA LOCAL
INFILE 'myfile.csv'
INTO TABLE mydatabase.`mytable`
FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '"' ESCAPED BY '\\'
LINES TERMINATED BY '\r\n'
(my_date, any_string_column);

Any idea why 0000-00-00 00:00:00 only happens for the very first row and only when it is the very first column? Thanks.

Your editor is saving the file with a BOM (Byte Order Mark) character at the beginning, which MySQL doesn't recognize. You need to disable this setting.
