How can I update query joining multiple tables.

Hi team,

I want to update a column of TABLE 1, but it should rally with TABLE 2. Under certain conditions, that it should be updated.

I created as below. But it does not work.

Can you please suggest me how can I do?

UPDATE Table1
SET Table1.Column1 = 'name'
FROM Table1 T1, Table2 T2
WHERE T1.id = T2.id
and T1.name  = T2.Name
And T1.id = UPDATE Table1
  SET Table1.Column1 = 'name'
FROM Table1 T1, Table2 T2
WHERE T1.id = T2.id
and T1.id = '100';


Hello

Your update statement is not at all clear.

Something like below:

UPDATE Table1 T1

THE T1 VALUE. Column1 = 'name '.

WHERE EXISTS (SELECT 1 FROM Table2 T2 WHERE)

T1.ID = T2.id and T1.name = T2. (Name);

(Or)

UPDATE Table1 T1

THE T1 VALUE. Column1 = 'name '.

WHERE EXISTS (SELECT 1 FROM Table2 T2 WHERE)

T1.ID = T2.id and T1.name = T2. The name) and T1.id = '100';

  • How can I update the data in mysql using the button defined in the table?

    Hello

    right now I am doing my project for the online election system using dreamweaver cc14. I create a table using php code to bind the data to mysql, and in this painting, I create also a button "vote" for voters to vote. My question is, how can I update my polling data in the mysql database when voters push button "vote" based on the id of the candidates? Here is my code I try:

    <form method="post" id="form1">
      <?php
$servername = "localhost";
$username = "root";
$password = "pass";
$dbname = "ses";


// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
     die("Connection failed: " . $conn->connect_error);
} 


$sql = "SELECT No, Calon, ID, Jurusan, Image FROM candidates";
$result = $conn->query($sql);


if ($result->num_rows > 0) {
     echo "<table >
  <tr>
  <th>NO</th>
  <th>Candidate</th>
  <th>INFO</th>
  <th>Vote</th>
  </tr>";
     // output data of each row
     while($row = $result->fetch_assoc()) {
         echo "<tr>
  <td>" . $row["No"]. "</td>
  <td><img src=" . $row['Image'] . "></td>
  <td><br/>-" . $row["Calon"]. " <br/>-" . $row["ID"]. " <br/>-" . $row["Jurusan"]. "<br/></td>
  <td><input type="."submit"." name=".$row["Calon"]." id=".$row["No"]. " value="."Vote"."></td>

  </tr>";
  if(isset($_POST["".$row['No'].""])){

  $vote_sachin = "UPDATE candidates SET Undi=Undi+1 WHERE No=".$row["No"]. "";

  $run_sachin = mysqli_query($conn, $vote_sachin);


}
    }
  echo "</table>";
} else {
     echo "0 results";
}






$conn->close();
?>




    </form>

    I hope someone can help me in this area, because I'm still new in this programming language.

    Thank you.

    Youre probably going to insert a 'radio button' next to the names of candidates and recover the database ID of that (I guess that the ID is the primary key in your database that uniquely identifies each record.

    His great confusion because you seem to update the database to aid WHERE no = "." $row ["no"]. so I don't know that ID is the primary key?

    IF "No" IS your master database key, you need to change the code below:

    TO:

    Here's the complete code based on the ID of your primary database key.

    <>

    $servername = "localhost";

    $username = 'root ';

    $password = "pass";

    $dbname = 'his ';

    Create the connection

    $conn = new mysqli ($dbname, $servername, $username, $password);

    Check the connection

    If {($conn-> connect_error)

    Die ("connection failed:".) $conn-> connect_error);

    }

    $sql = "SELECT No, Calon, ID, Jurusan, Image OF candidates";

    $result = $conn-> Query;

    If you click on the button "vote" form run the code to update the database below

    {if (isset($_POST['vote']))}

    Get the value of the ID of the radio button form field and store it in a table.

    $update_vote = $_POST ['candidate_id'];

    loop in the table and update the database

    foreach ($update_vote as $value) {}

    $vote_sachin = ' candidates UPDATE SET Undi = Undi + 1 WHERE ID = ".". " $value. » « ;"

    $run_sachin = mysqli_query ($conn, $vote_sachin);

    }

    }

    ?>

    <>

    If ($result-> num_rows > 0) {}

    ECHO '.

    ";

    each line output

    While ($row = {$result-> fetch_assoc())}

    ECHO '.

    ";

    }

    ECHO '.

    ";

    ECHO '.

    NO. Candidate INFO To the vote
    " . $row ["no"]. "
    -" . $row ["Calon"]. "
    -" . $row ['ID']. "
    -" . $row ["Jurusan"]. "
    ";

    } else {}

    echo "0 results."

    }

    $conn-> close();

    Version 8 iMovie is not compatible with El Capitan, so you must upgrade to iMovie 10.1.2. To connect to the App Store and look under the purchased Tab. Find iMovie and Garage Band. If they are not there, it may be that the free updates are not available in iMovie 8. I'm not sure about this. They are free to version 9. You can also go to your account and make sure iMovie is not hidden.

  • Satellite L300D - 24 d how can I update the graphics driver?

    Hello

    How can I update the driver for my ATI Radeon 3100 graphics card. (Win Vista 32 bit)
    I download and installed the new ATI Catalyst worms. 10.12.

    If I change my graphics card options, there is always the old driver installed... Worms. 22.04.08 8.479.0.0
    Also, it is not possible to change the settings for graphic resolution higher than 1280 X 800 Pix.

    Thanks for the help,

    Fun1975

    First, you must use the page to Toshiba display driver.
    The use of other drivers can lead to highest GPU temperature and cause overheating.

    But if you want to use other drivers, you can do so at you own risk.
    In order to install another driver, go to Device Manager, mark the graphics card, then press on uninstall button.
    Then the driver should be uninstalled.

    After you restart the laptop, you can try to install the new version.

    > It is also not possible to change the settings for graphic resolution higher than 1280 X 800 Pix.
    The internal screen for laptop supports 1280 x 800 high resolution. It is not possible to choose a higher value.
