Question

Im currently inserting a large amount (100k+) of rows into a table as follows:

//START of a loop

$updatedData[] =  '(
                      "'.$field_1.'",
                      "'.$field_2.'",
                      "'.$field_3.'"
                   )';
//END of loop

$updatedData = implode(',', $updatedData);

$query = "INSERT INTO table (field_1,field_2,field_3) VALUES $updatedData";

This is all working perfectly, but now I’m looking for a way to update a row instead of insert a new one if $field_1 and $field_3 are duplicates.

Answer 1

Just take counter of your $updatedData.

And run that in loop this will run as you want.

All the best.
