MySQL Error 4143: Missing ENCLOSED BY Character
Description
This error occurs during data import operations (e.g., LOAD DATA INFILE) when MySQL expects field values to be enclosed by a specific character, but it encounters a field that is not properly enclosed or is missing the expected character. It indicates a mismatch between the data file's format and the parsing rules defined in the SQL statement.
Error Message
Missing ENCLOSED BY character at row %ld in file '%s'. Add OPTIONALLY to the ENCLOSED BY clause to allow this input.
Known Causes
4 known causesMismatched ENCLOSED BY Character
The character specified in the ENCLOSED BY clause of your SQL statement does not precisely match the actual character used to enclose field values in the data file.
Unenclosed Field Value
A field value in the input file is not enclosed by the specified character, even though the ENCLOSED BY clause expects all fields to be enclosed.
Strict ENCLOSED BY Enforcement
The ENCLOSED BY clause is used without the OPTIONALLY keyword, requiring every field to be enclosed, but some fields in your data file are not.
Malformed Input Data
The input file contains unexpected characters or structural inconsistencies that prevent MySQL from correctly parsing the enclosing characters at the indicated row.
