PHP 中的 SQL 是否有等效的 NOT IN 运算符?
if(count($result1) > 0) {
$query_transline_conflict = "SELECT * FROM transaction_line as tl LEFT JOIN transaction as t ON tl.transaction_id = t.transaction_id LEFT JOIN resources as r ON tl.resource_id = r.resource_id WHERE t.equipment_class_id = '$equipment_class_id' AND tl.returned = '0'";
$result_transline_conflict = mysqli_query($conn, $query_transline_conflict);
$result2 = mysqli_fetch_all($result_transline_conflict,MYSQLI_ASSOC);
$x = 0;
foreach($result2 as $row){
$already_booked_range = getDatesFromRange($row['start_date'],$row['end_date']);
$new_array_already_booked[$x] = $already_booked_range;
$x++;
}
我有一个正在输入的 start_date 和 end_date。现在$new_array_already_booked存储将被比较的日期范围。所以我想使用 NOT IN 运算符来比较 php。我希望我说得通。仍然是初学者并试图学习。
