MySQL Error 4147: Unexpected Row Terminator in File
Description
This error occurs during bulk data loading operations (e.g., `LOAD DATA INFILE`) when MySQL encounters a character it interprets as a row terminator in an unexpected place. It typically signifies a mismatch between the actual data file's structure and the specified import parameters, leading to incorrect parsing of rows and potential data loss for subsequent columns.
Error Message
Unexpected row terminator found at row %ld in file '%s'. Data for some columns is missing.
Known Causes
4 known causesMismatched Line Terminator Setting
The `LINES TERMINATED BY` clause in the `LOAD DATA INFILE` statement does not accurately reflect the actual row termination characters used in the source data file.
Embedded Line Terminators in Data
Data fields within the source file contain characters (e.g., newlines) that MySQL incorrectly interprets as row terminators, causing premature row termination.
Corrupted or Malformed Source File
The input data file is corrupted or contains inconsistent formatting, leading to unexpected characters being encountered by the parser.
Character Set Mismatch
A discrepancy between the file's character encoding and the character set specified for the table or connection can cause certain bytes to be misinterpreted as row terminators.
