MySQL Error 4150: Data Import Formatting Error
Description
This error occurs during data import operations, typically with `LOAD DATA INFILE`, when MySQL encounters unexpected characters after what it believes should be the end of a column. It indicates a mismatch between the expected data format (specified by `FIELDS TERMINATED BY`, `ENCLOSED BY`, etc.) and the actual structure of the input file.
Error Message
Unexpected characters after column terminator found at row %ld in file '%s'.
Known Causes
4 known causesIncorrect Delimiter Specification
The `FIELDS TERMINATED BY` or `ENCLOSED BY` clause in your `LOAD DATA INFILE` statement does not accurately reflect the delimiters present in the input file.
Excess Data in Row
A specific row in the input file contains more columns or characters than MySQL expects, causing it to find 'unexpected characters' after parsing the defined fields.
Inconsistent Line Endings
The input file uses inconsistent line ending characters (e.g., a mix of LF and CRLF) or the `LINES TERMINATED BY` clause does not match the file's actual line termination.
Malformed Input File
The input file itself is corrupted or contains hidden, non-printable characters that interfere with MySQL's ability to correctly parse the data.
