Description
MariaDB Error 1262 indicates that a row being processed (typically during an INSERT or LOAD DATA operation) contained more data values than there were target columns. This leads to truncation, meaning the excess data was discarded, and a warning is issued. It signifies a mismatch between the data structure being provided and the expected table structure.
Error Message

Known Causes
3 known causesMismatched Column Count
The number of data values provided in the input for a row exceeds the number of columns defined in the target table or explicitly listed in the `INSERT` statement.
Incorrect Data Delimiter
When importing data (e.g., via `LOAD DATA INFILE`), the specified delimiter does not match the actual delimiter in the source file, causing incorrect parsing and an excess of perceived columns.
Malformed Input Data
The input data itself contains structural errors, such as unescaped delimiters within a field, leading the parser to misinterpret column boundaries and register too many values.
