Question

I have a php array of “primary key” values, which correspond to just a few rows of a very long table of data, saved on a MySql database.
How can I fetch with just one query only those rows. Is it possible or will I need to make one query per primary key? eg: SELECT * FROM table1 WHERE key = 8573

Thanks,
Patrick

Answer 1

Select * from table WHERE primary_key IN (8573,8574,8578)

for your php array you could use implode

$key_array = implode(",", $array);

Select * from table WHERE primary_key IN ($key_array)
