MySQL Error 4142: File Lines Less Than Ignore
Description
This error occurs during data loading operations, typically when using the `LOAD DATA INFILE` statement with an `IGNORE N LINES` clause. It signifies that the number of lines specified to be ignored at the beginning of the file is greater than or equal to the total number of lines actually present in the data file. MySQL cannot skip lines that do not exist, leading to this failure.
Error Message
The first file being loaded contained less lines than the ignore clause
Known Causes
3 known causesMisconfigured Ignore Clause
The `IGNORE N LINES` value in your `LOAD DATA` statement is set too high, exceeding the actual number of lines in the input file.
Empty or Short Data File
The input data file contains very few lines, or is completely empty, making it impossible for MySQL to ignore the specified number of lines.
Unexpected File Content
The file content is not as expected, possibly due to corruption or an incorrect format, leading MySQL to misinterpret the actual number of lines.
