MySQL Error 1409: Fixed-Size Row Load Mismatch
Description
This error occurs when MySQL attempts to load data from a file formatted with fixed-size rows into a target (like a column or variable) that expects or handles variable-size data, or vice-versa. It indicates a fundamental incompatibility in data interpretation during an import operation, typically preventing the successful transfer of data.
Error Message
Can't load value from file with fixed size rows to variable
Known Causes
4 known causesData Type Mismatch
The target column or variable's data type (e.g., VARCHAR for variable length, CHAR for fixed length) does not align with the expected data format of the fixed-size rows in the source file.
Incorrect LOAD DATA INFILE Options
The `LOAD DATA INFILE` statement might be missing or incorrectly specifying options that describe the file structure, leading MySQL to misinterpret the fixed-size row format.
Schema Design Inconsistency
The table schema, particularly the choice between `CHAR` and `VARCHAR` column types, conflicts with the fixed-size row structure of the input file, causing issues during data insertion.
Implicit Type Conversion Failure
MySQL is unable to implicitly convert data from a fixed-size row format in the file to a variable-size type expected by the target variable or column due to fundamental structural differences.
