MariaDB Error 1409: Fixed-Size Row Load Mismatch
Description
This error occurs when MariaDB attempts to load data from a source (often a file) where rows are interpreted as having a fixed size, but the target (a variable or column) expects variable-sized data, or vice-versa. It typically arises during data import operations like `LOAD DATA INFILE` when there's a discrepancy between the data's actual format and how MariaDB is instructed to read it.
Error Message
Can't load value from file with fixed size rows to variable
Known Causes
3 known causesData Type/Length Mismatch
The data type or declared length of columns in the target table (e.g., `VARCHAR` vs. `CHAR`) conflicts with the fixed or variable-length nature of the data being read from the source file.
Incorrect `LOAD DATA` Syntax
The `LOAD DATA INFILE` statement uses `FIELDS` or `LINES` clauses (e.g., `FIXED`, `VAR`) that misrepresent the actual structure of the input file's rows or columns.
Source File Format Discrepancy
The actual structure of the input data file (e.g., a CSV without consistent delimiters or with unexpected padding) does not match MariaDB's expectation for fixed or variable-length rows during parsing.
