You can use the LOAD_FILE() function to read the entire file into a variable, and then use a loop to parse each line out of the variable:

SET @file := LOAD_FILE('path/to/file.csv');
while LOCATE('\n', @file) do...

It will be much slower than LOAD DATA INFILE would be.

well thanks for your suggestion,
but what do you mean by variable?
is it a temporary table?

can you please give more detail about the loop,

The variable is not a temporary table; it's just a string that holds the entire file contents.

The loop would have to hunt for line separators in that string, and then within that loop hunt for field separators, and thereby break the string up into the individual fields.

I really think it would be much simpler to drop the requirement for a stored procedure, and just call LOAD DATA INFILE directly from your application.
