行數與打印的行數不同

Question

所以我試圖將我的數據庫中的所有行都回顯到一個文件中，問題在於它缺少大約2800行，無法找到它們。

我試圖把一個try-catch，獲取數據的同時進行手動的循環不同的方法槽的結果，移動與data_seek指針....

所以這裏是代碼

$sql = 'SELECT connectedProducts,id,price,masterprice,cardprice,name,url,fullImage,categoryid1,categoryid2,categoryid3,sku,connectedCategory,connectedPrice,uniqueID 
     FROM sku_new 
     where name !="" and stock="in stock" and price != "" and masterprice != "%No%" 
     and fullimage != "http:" AND price != "No disponible" 
     and masterprice !="No disponible" and cardprice != "No disponible"'; 
$result=mysqli_query($con,$sql); 


while ($row = mysqli_fetch_array($result, MYSQLI_ASSOC)) { 
    echo $row['sku']."\r\n"; 
} 

這將打印38854行數據。然而，當我這樣做：

$sql = 'SELECT connectedProducts,id,price,masterprice,cardprice,name,url,fullImage,categoryid1,categoryid2,categoryid3,sku,connectedCategory,connectedPrice,uniqueID 
     FROM sku_new 
     where name !="" and stock="in stock" and price != "" and masterprice != "%No%" 
     and fullimage != "http:" AND price != "No disponible" 
     and masterprice !="No disponible" and cardprice != "No disponible"'; 
$result=mysqli_query($con,$sql); 

$row_cnt = $result->num_rows; 
echo $row_cnt; 

我得到41695 ...所以我不知道發生了什麼行的其餘部分，他們似乎只是dissapear，我已經嘗試了不同的方法，試圖讓他們並沒有什麼似乎工作...但是，如果我直接在數據庫上的DB可視化器上查詢，我得到41695行顯示正確...我一直在這個問題上打破我的頭，它沒有任何意義..我是什麼做錯了？

=====編輯========= 如果我從修改查詢：

$sql = 'SELECT connectedProducts,id,price,masterprice,cardprice,name,url,fullImage,categoryid1,categoryid2,categoryid3,sku,connectedCategory,connectedPrice,uniqueID 
      FROM sku_new 
      where name !="" and stock="in stock" and price != "" and masterprice != "%No%" 
      and fullimage != "http:" AND price != "No disponible" 
      and masterprice !="No disponible" and cardprice != "No disponible"'; 

要：

$sql = 'SELECT id,price,masterprice,cardprice,name,url,fullImage,categoryid1,categoryid2,categoryid3,sku,connectedCategory,connectedPrice,uniqueID 
      FROM sku_new 
      where name !="" and stock="in stock" and price != "" and masterprice != "%No%" 
      and fullimage != "http:" AND price != "No disponible" 
      and masterprice !="No disponible" and cardprice != "No disponible"'; 

我得到的所有41695行！ ！這沒有任何意義，我不修改WHERE指令！

我認爲$row['sku']可以爲空的某些記錄。試試這個代碼，然後檢查總數。

$i = 1; 
while ($row = mysqli_fetch_array($result, MYSQLI_ASSOC)) { 
    echo $i." - ".$row['sku']."\r\n"; 
    $i++; 

}
