hostSo我知道如何从MYSQL内部直接获得两个字段连接，但有麻烦让它与我的PHP工作。
直接来自MYSQL = SELECT CONCAT(ConfigurationItem, ' - ', ,Buzzword) FROM Buzz;
但是我如何将它合并到下面的PHP中，我已经研究了很多。我想将两个字段ConfigurationItem和Buzzword合并到一个名为shortdescription的字段中，而不必在每次提交PHP时通过MYSQL手动进行。
<?php
$con = mysql_connect("host","username","password");
if (!$con)
{
die('Could not connect: ' . mysql_error());
}
mysql_select_db("buzz_feed", $con);
$sql = "INSERT INTO Buzz (BuzzID, ConfigurationItem, Buzzword, OccurrenceDate, PostingDate, TierStatus, MasterTicket)
VALUES
('$_POST[BuzzID]','$_POST[ConfigurationItem]','$_POST[Buzzword]','$_POST[OccurrenceDate]','$_POST[PostingDate]','$_POST[TierStatus]','$_POST[MasterTicket]')";
if (!mysql_query($sql,$con))
{
die('Error: ' . mysql_error());
}
echo "Buzz Phrase information updated";
mysql_close($con)
?>
我在php中将它们连接在一起作为插入。虽然在select语句中使用它们并没有错。事实上，我会选择这种方式，因为它是冗余的——实际上，您需要两次插入相同的数据。但这应该能满足你的要求。我也更正了你在查询中的引号。还有google sql injection
<?php
$con = mysql_connect("host","username","password");
if (!$con)
{
die('Could not connect: ' . mysql_error());
}
mysql_select_db("buzz_feed", $con);
$sql = "INSERT INTO Buzz (BuzzID, ConfigurationItem, Buzzword,
OccurrenceDate, PostingDate,
TierStatus, MasterTicket, shortdescription)
VALUES
('".$_POST['BuzzID']."','".$_POST['ConfigurationItem']."',
'".$_POST['Buzzword']."','".$_POST['OccurrenceDate']."','".$_POST['PostingDate']."',
'".$_POST['TierStatus']."','".$_POST['MasterTicket']."',
'".$_POST['ConfigurationItem']."' - '". $_POST['Buzzword']."')";
if (!mysql_query($sql,$con))
{
die('Error: ' . mysql_error());
}
echo "Buzz Phrase information updated";
mysql_close($con)
?>
我最终通过在INSERT INTO行插入"ShortDescription"来解决我的问题，然后告诉它在"ShortDescription"字段中插入我想要的两个字段，并在连字符之间使用双空格，我能够得到我想要的效果，结果是这样的"示例-示例"，请参阅下面的代码
$sql = "INSERT INTO Buzz (BuzzID, ConfigurationItem, Buzzword, OccurrenceDate, PostingDate, TierStatus, MasterTicket, ShortDescription)
VALUES
('$_POST[BuzzID]','$_POST[ConfigurationItem]','$_POST[Buzzword]','$_POST[OccurrenceDate]','$_POST[PostingDate]',
'$_POST[TierStatus]','$_POST[MasterTicket]','$_POST[ConfigurationItem]' ' - ' '$_POST[Buzzword]')";
