Description:
a csv file with lines:
  value1,value2,,value4

gives an error. This worked in earlier versions by setting sql_mode=''

An empty field is not intended as a NULL value in financial data. It means there is no value given. I think this is true in general but it is certainly so for char/text fields.

How to repeat:
load data infile ...  reading a line as above

Suggested fix:
Either restore earlier setting for sql_mode or add a new setting.

Hi Mr. Deanult,

Thank you for your bug report.

However, we need more feedback from you in order to try to repeat it. We need a table in question and the input file.

Also, do note that 5.6 is no longer maintained. Next, MySQL is improving type checking , so if it is a problem with some type mismatch, it will not be considered a bug.
