我试图将另一个表中的select语句的结果插入到另一个表中。 select语句有效,但insert语句不起作用。请帮帮我。
$query="SELECT * FROM subject WHERE sub_code = '$enrol' ";
$result = mysql_query($query);
while($row = mysql_fetch_array($result)) {
$csubject=$row['sub_name'];
$cday=$row['sub_day'];
$ctime=$row['sub_time'];
echo "<strong>". $csubject . "</strong>";
}
$query = mysql_query("INSERT INTO client (client_csub_code,client_csub_name,client_csub_day,client_csub_time) VALUES ('$enrol','$csubject','$cday','$ctime')");
header("Location:homeclient.php");
?>

您询问如何将这两个作为一个查询。
这是:
$query = mysql_query("INSERT INTO `client` ( `client_csub_code`, `client_csub_name`, `client_csub_day`, `client_csub_time` ) SELECT `sub_code`, `sub_name`, `sub_day`, `sub_time` FROM `subject` WHERE `code` = '$enrol'");
// I would also add error checking
if ( mysql_errno() )
echo mysql_error();

$query="SELECT * FROM subject WHERE sub_code = '$enrol' ";
$result = mysql_query($query);
while($row = mysql_fetch_array($result)) {
$csubject=$row['sub_name'];
$cday=$row['sub_day'];
$ctime=$row['sub_time'];
echo "<strong>". $csubject . "</strong>";
$query = mysql_query("INSERT INTO client (client_csub_code,client_csub_name,client_csub_day,client_csub_time) VALUES ('$enrol','$csubject','$cday','$ctime')");
}
header("Location:homeclient.php");
?>
尝试更改为此。目前您的查询超出了您的查询范围,它只会运行一次,$ csubject等的值将始终是您获取结果的最后一个值。
