在mysql上获取行[关闭]

Question

AddInfo a = new AddInfo();    

int c;    
c = a.getRw();    

String sql = "select row(*) * from coproproject.table (user_id, user_lastname, user_firstname, user_mi, user_gender, user_age, bday_month, bday_date, bday_year, user_address, user_status, user_nationality, user_contact, user_email) value (?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?) ";

我想获取c（我的数据库中的行数（coproproject.table））

我希望我的数据库中字段的字符串值出现在我的文本字段中

我该怎么做？

Answer 1

我认为，您对 SELECT 和 INSERT 感到困惑。好吧，这就是我认为您正在寻找的东西。 SELECT 使用 MySQLi：

$YourConnection=mysqli_connect("YourHost","YourUsername","YourPassword","YourDatabase");

if(mysqli_connect_errno()){

echo "Error".mysqli_connect_error();
}

$result = ($YourConnection, "SELECT * FROM coproproject");
while($row=mysqli_fetch_array($result)){

$id=$row['user_id'];
echo "<input type='text' name='userid' value='$id'>"; /* PUT TO A TEXT FIELD THE USER_ID */

echo " ".$row['user_lastname']." ".$row['user_firstname']." ".$row['user_mi']." ".$row['user_gender']." ".$row['user_age']." ".$row['bday_month']." ".$row['bday_date']." ".$row['bday_year']." ".$row['user_address']." ".$row['user_status']." ".$row['user_nationality']." ".$row['user_contact']." ".$row['user_email']."<br>";
}

$numofRows=mysqli_num_rows($result); /* GET THE NUMBER OF FETCHED ROWS */
echo $numofRows;

?>
