consider the following simplified queries (php using
heredoc):
$sql_1 = <<<_EOSQL
select count(inspect)
from t_inspect, t_product, t_test_area
where t_product.product_num = 1
and t_test_area.id = 5
_EOSQL
$sql_2 = <<<_EOSQL
select count(inspect)
from t_inspect, t_product, t_test_area
where t_product.product_num = 1
_EOSQL
what is the best way to handle both of these cases in
one statement?
i know it would take the form of $sql_1, but what
value should i feed to t_test_area.id? is there
syntax that will just ignore it or do i need to send a
value of 'NOT NULL'? will NOT NULL slow down the
query when compared to $sql_2?
am i missing a better way to structure these queries?
as always, tia...
