Question

有可能在php中有2个不同的sql语句吗？我的意思是例如

<?php
$servername = "localhost";
$username = "root";
$password = "root";
$dbname = "tsukishiro";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}
$sql = "SELECT DISTINCT student_no FROM grades_tbl2 WHERE student_no ='C2012-02918'";
$sql = "SELECT * FROM grades_tbl2 WHERE student_no ='C2012-02918' ";
$result = $conn->query($sql);
if ($result->num_rows > 0) {
while($row = $result->fetch_assoc()) {
        echo "<tr><td>".$row["student_no"]."</td><td>".$row["last_name"]." ".$row["first_name"]." ".$row["middle_name"]."</td><td>".$row["subject_code"]."</td><td>" .$row["subject_desc"]."</td><td>".$row["trans_final"]."</td><td>".$row["remarks"]."</td><td>".$row["subject_prof"]."</td></tr>";
    }
    echo "</table>";
} else {
    echo "0 results";
}
$conn->close();
?>

所以我想分开不同的语句，以便其他sql语句与第一个语句不同。你能帮助我吗？这个新的

2个sql语句分离
