MariaDB Error 1475: Ambiguous Field Terminator
Description
This error occurs during data import or export operations (e.g., `LOAD DATA INFILE` or `SELECT ... INTO OUTFILE`) when the first character specified in the `FIELDS TERMINATED BY` clause creates an ambiguity for the parser. MariaDB cannot reliably distinguish between the field terminator and other data or delimiters, requiring explicit enclosure. This typically happens when the terminator character itself is found within the data or conflicts with other parsing rules.
Error Message
First character of the FIELDS TERMINATED string is ambiguous; please use non-optional and non-empty FIELDS ENCLOSED BY
Known Causes
3 known causesAmbiguous Terminator Character
The character designated as the `FIELDS TERMINATED BY` delimiter is identical to the first character of data values or other significant characters in the input file, leading to parsing confusion.
Missing Field Enclosure
When the field terminator character might appear within the data itself, not using a `FIELDS ENCLOSED BY` clause allows for ambiguity, as MariaDB cannot distinguish between the terminator and actual data.
Conflicting Delimiter Choices
The chosen `FIELDS TERMINATED BY` character inadvertently matches or conflicts with other delimiters (e.g., `LINES TERMINATED BY`) or special characters within the file, making parsing unclear.
