mysql_query不起作用並給出錯誤

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在工作，但是后來我在$ yaya中添加了更多值，並且現在不工作。 我沒有錯過任何逗號，我檢查了一下。 它沒有更新或插入。

“您的SQL語法有錯誤；請查看與您的MySQL服務器版本相對應的手冊，以正確使用語法'kill = kill + 0，death = death + 1，assist = Assist + 14，cs = cs + 28，cspm =第1行的csp'”

第1行的'kill = kill + 0，death = death + 1，assist =助攻+ 14，cs = cs + 28，cspm = csp'

$ yaya看起來像什么

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

編輯：我將yaya字符串更改為

$yaya = "`kill` = `kill` + {$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]}";

我將kill改為kill ，將{$ playergolds [$ x]}更改為'{$ playergolds [$ x]}”，因為它具有“ b”（例如6.6b並引用了varchars（不確定是否有必要））。

Answer 1

由於rol是VARCHAR ，因此您需要在該值rol加上引號。

rol = {$rols[$x]}

應該：

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

您可以在$yaya的值中看到：

rol = Support

它應該是

rol = 'Support'

如果您將預查詢與PDO或mysqli一起使用，則不會有這樣的問題。

另一個問題是， kill是保留字。 要將其用作列名，您需要使用反引號對其進行轉義：

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

同樣，當使用ON DUPLICATE KEY UPDATE ，您不需要重復VALUES列表中的所有值。 你可以寫

rol = VALUES(rol)

這意味着更新應該使用與沒有重復鍵時插入的值相同的值。 所以你可以這樣寫：

$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)";
