Hi,
I have a question on LOAD DATA INFILE command.
I have a table with 10 columns. Is it possible to update only few
columns of this table using LOAD DATA INFILE?
No. As you found out Load Data loads the specified columns and sets the
other columns to NULL. The only way around this is to write the current
column values that you want to save back out to the text file. Or load the
data into a second temporary table with just the columns you need, and then
do an Update to the original table (assuming of course all of the data in
the text file are updates and not new rows otherwise you'll then have to
join the original table with the temp table to find the new rows then add
those to the original table.) Whew!
