您好我正在尝试从 csv 文件更新我的 MYSQL 数据库中的表 testprod。（我在这里找到了代码，并根据我的需要对其进行了更新，几乎 :)）
它会更新，但十进制值会被截断，并且会丢失 (.) 之后的任何信息，例如 400.25 被缩减为 400
这是 csv 文件的示例
'Product_ID','Model','HighPic','ManuId','Model_Name','categories_id','categories_image','parent_id','sort_order','categories_name','categories_description','categories_keywords','Name','Image','Price','Supplier','Weight','Stock','datetime'
2055332,,,,,,,,,,,,,,800.4,,,'1',
3916211,,,,,,,,,,,,,,444,,,'15',
12073922,,,,,,,,,,,,,,737.6215,,,'0',
4593772,,,,,,,,,,,,,,2822.4,,,'4',
1684786,,,,,,,,,,,,,,4333.2,,,'1',
这是php代码。
<?php
// set local variables
$connect = mysql_connect("localhost","db","password") or die('Could not connect: ' . mysql_error());
$handle = fopen("dailyupdates.csv", "r");
// connect to mysql and select database or exit
mysql_select_db("rapido_creloaded", $connect);
// loop content of csv file, using comma as delimiter
while (($data = fgetcsv($handle, 1000, ",")) !== false) {
$Product_ID = $data[0];
$price = $data[14];
$stock = $data[17];
$query = 'SELECT Product_ID FROM testprod';
if (!$result = mysql_query($query)) {
continue;
}
if ($line = mysql_fetch_array($result, MYSQL_ASSOC)) {
// entry exists update
$query = "UPDATE testprod SET price ='$price' , stock = '$stock'
WHERE Product_ID = '$Product_ID'";
mysql_query($query);
if (mysql_affected_rows() <= 0) {
// no rows where affected by update query
}
} else {
// entry doesn't exist continue or insert...
}
mysql_free_result($result);
}
fclose($handle);
mysql_close($connect);
?>
