mysql_query不起作用并给出错误

Question

while($x < 10)
    {
    $str = "( NULL, '{$players[$x]}', '1' , 0 + {$sonucs[$x]},oynananoyun - win,'{$rols[$x]}','{$teams[$x]}','{$playerkills[$x]}','{$playerdeaths[$x]}','{$playerassists[$x]}','{$creeps[$x]}','{$dmgs[$x]}','{$dpms[$x]}','{$wards[$x]}','{$playergolds[$x]}','{$gpms[$x]}', '{$goldpercantages[$x]}', 0 + {$fbs[$x]},'{$dmgpercantages[$x]}', '{$wardscleared[$x]}', '{$wpm[$x]}', '{$wcpm[$x]}','{$wardpercents[$x]}', '{$wardsclearedpercents[$x]}', '{$cspms[$x]}')";
    $yaya = "kill = kill + {$playerkills[$x]}, death = death + {$playerdeaths[$x]},assist = assist + {$playerassists[$x]},cs = cs + {$creeps[$x]}, cspm = cspm + {$cspms[$x]}, takim = {$teams[$x]}, dmg = dmg + {$dmgs[$x]}, dpm = dpm + {$dpms[$x]},wardplaced = wardplaced + {$wards[$x]}, oynananoyun = oynananoyun + 1, win = win + {$sonucs[$x]}, rol = {$rols[$x]}, gold = gold + {$playergolds[$x]}, goldshare = goldshare + {$goldpercantages[$x]}, gpm = gpm + {$gpms[$x]}, fb = fb + {$fbs[$x]}, dmgshare = dmgshare + {$dmgpercantages[$x]}, wardcleared = wardcleared + {$wardscleared[$x]}, wardplacedpm = wardplacedpm + {$wpm[$x]}, wardclearedpm = wardclearedpm + {$wcpm[$x]}, wardplacedshare = wardplacedshare + {$wardpercents[$x]}, wardclearedshare = wardclearedshare + {$wardsclearedpercents[$x]}";
    mysql_query ("INSERT INTO playerstats18 (`id`,`player`,`oynananoyun`,`win`,`lose`,`rol`,`takim`,`kill`,`death`,`assist`,`cs`,`dmg`,`dpm`,`wardplaced`,`gold`,`goldshare`,`gpm`,`fb`,`dmgshare`,`wardcleared`,`wardplacedpm`,`wardclearedpm`,`wardplacedshare`,`wardclearedshare`,`cspm`) VALUES $str ON DUPLICATE KEY UPDATE $yaya");
    $x++;
    }

mysql_query正在运行，但后来我在$ yaya添加了更多的值，现在它还没有运行。我没有遗漏任何逗号，我查了一下。它没有更新或插入。

“您的SQL语法有错误;请查看与您的MySQL服务器版本对应的手册，以便在'kill = kill + 0，death = death + 1，assist = assist + 14，cs附近使用正确的语法= cs + 28，cspm = csp'在第1行“

'kill = kill + 0，death = death + 1，assist = assist + 14，cs = cs + 28，cspm = csp'在第1行

$ yaya喜欢什么

kill = kill + 0, death = death + 1,assist = assist + 14,
cs = cs + 28, cspm = cspm + 1, takim = DP,
dmg = dmg + 3.0, dpm = dpm + 110,wardplaced = wardplaced + 43,
oynananoyun = oynananoyun + 1, win = win + 1 , rol = Support,
gold = gold + 7.7b, goldshare = goldshare + 14.1,
gpm = gpm + 283, fb = fb + 0,
dmgshare = dmgshare + 6.4, wardcleared = wardcleared + 9,
wardplacedpm = wardplacedpm + 1.58,
wardclearedpm = wardclearedpm + 0.33,
wardplacedshare = wardplacedshare + 29.6,
wardclearedshare = wardclearedshare + 31

编辑：我将yaya字符串更改为

$yaya = "`kill` = `kill` + {$playerkills[$x]}, 
death = death + {$playerdeaths[$x]},
assist = assist + {$playerassists[$x]},
cs = cs + {$creeps[$x]}, 
cspm = cspm + {$cspms[$x]}, 
takim = '{$teams[$x]}', 
dmg = dmg + {$dmgs[$x]}, 
dpm = dpm + {$dpms[$x]},
wardplaced = wardplaced + {$wards[$x]}, 
oynananoyun = oynananoyun + 1, 
win = win + {$sonucs[$x]}, 
rol = '{$rols[$x]}', 
gold = gold + '{$playergolds[$x]}', 
goldshare = goldshare + {$goldpercantages[$x]}, 
gpm = gpm + {$gpms[$x]}, fb = fb + {$fbs[$x]}, 
dmgshare = dmgshare + {$dmgpercantages[$x]}, 
wardcleared = wardcleared + {$wardscleared[$x]}, 
wardplacedpm = wardplacedpm + {$wpm[$x]}, 
wardclearedpm = wardclearedpm + {$wcpm[$x]}, 
wardplacedshare = wardplacedshare + {$wardpercents[$x]}, 
wardclearedshare = wardclearedshare + {$wardsclearedpercents[$x]}";

我将杀戮改为kill， {$ playergolds [$ x]}到'{$ playergolds [$ x]}'，因为它有“b”（例如6.6b） 和引用的varchars（不确定是否有必要）。

Answer 1

由于rol是VARCHAR，因此您需要在值周围加上引号。

rol = {$rols[$x]}

应该是：

rol = '{$rols[$x]}'

您可以在$yaya：

的值中看到这一点

rol = Support

应该是

rol = 'Support'

如果您使用PDO或mysqli准备好的查询，则不会出现这样的问题。

另一个问题是kill是保留字。要将其用作列名，您需要使用反引号来转义它：

`kill` = `kill` + {$playerkills[$x]}

此外，使用ON DUPLICATE KEY UPDATE时，您无需重复VALUES列表中的所有值。你可以写

rol = VALUES(rol)

表示更新应使用与没有重复键时插入的值相同的值。所以你可以写：

$yaya = "`kill` = `kill` + VALUES(`kill`), death = death + VALUES(death), assist = assist + VALUES(assist), 
        cs = cs + VALUES(cs), cspm = cspm + VALUES(cspm), takim = VALUES(takim), dmg = dmg + VALUES(dmg), 
        dpm = dpm + VALUES(dpm), wardplaced = wardplaced + VALUES(wardplaced), 
        oynananoyun = oynananoyun + 1, win = win + VALUES(win), rol = VALUES(rol), 
        gold = gold + VALUES(gold), goldshare = goldshare + VALUES(goldshare), gpm = gpm + VALUES(gpm), 
        fb = fb + VALUES(fb), dmgshare = dmgshare + VALUES(dmgshare), wardcleared = wardcleared + VALUES(wardcleard), 
        wardplacedpm = wardplacedpm + VALUES(wardplacedpm), wardclearedpm = wardclearedpm + VALUES(wardclearedpm), 
        wardplacedshare = wardplacedshare + VALUES(wardplacedshare), wardclearedshare = wardclearedshare + VALUES(wardclearedshare)";
