    <p>I have two tables in mysql</p> <p><code>practice_sheets</code> and <code>parent_pin</code></p> <p>And I want to use one select statement and get data from both tables. </p> <p>I have tried</p> <pre><code>$result = mysqli_query($con,"SELECT * FROM practice_sheets AND parent_pin WHERE student_name='$_SESSION[SESS_FIRST_NAME] $_SESSION[SESS_LAST_NAME]'"); </code></pre> <p>and also: </p> <pre><code>$result = mysqli_query($con,"SELECT * FROM practice_sheets, parent_pin WHERE student_name='$_SESSION[SESS_FIRST_NAME] $_SESSION[SESS_LAST_NAME]'"); </code></pre> <p>I've never tried to do this before and the previous solutions are what I found searching.</p> <p><strong>Update</strong></p> <p>I think it would help if I included my full code. the table data is going into a table on my page. the <code>student_name</code> field from the practice_sheets and <code>parents_student</code> from parent_pin will be matched.</p> <pre><code>&lt;?php $con=mysqli_connect(); // Check connection if (mysqli_connect_errno()){ echo "Failed to connect to MySQL: " . mysqli_connect_error(); } $result = mysqli_query($con,"SELECT * FROM practice_sheets WHERE student_name='$_SESSION[SESS_FIRST_NAME] $_SESSION[SESS_LAST_NAME]'"); $numrows = mysqli_num_rows($result); if($numrows == 0) { echo "&lt;div class='alert alert-danger'&gt;"; echo "No Entries, See your instructor for details."; echo "&lt;/div&gt;"; } else { echo "&lt;table class='mws-table table-striped table-hover'&gt;"; echo "&lt;thead align='center'&gt;"; echo "&lt;tr&gt;"; echo "&lt;th&gt;Sheet Number&lt;/th&gt;"; echo "&lt;th&gt;Total Minutes&lt;/th&gt;"; echo "&lt;th&gt;Due Date&lt;/th&gt;"; echo "&lt;th&gt;PIN&lt;/th&gt;"; echo "&lt;th&gt;View&lt;/th&gt;"; echo "&lt;/tr&gt;"; echo "&lt;/thead&gt;"; echo "&lt;tbody align='center'&gt;"; while($row = mysqli_fetch_array($result)){ if ($row["total_min"]&gt;=$row["required_min"]) { echo "&lt;tr class='success'&gt;"; echo "&lt;td&gt;" . $row['id'] .

    2. COWell you need to show us the tables, but essentially you'll use a join statement and join on PK/FK relationship. `SELECT table1.column1, table2.column2 FROM table1, table2 WHERE table1.column1 = table2.column1;` or you can use a union `SELECT column1, column2, column3 FROM table1 UNION SELECT column1, column2, column3 FROM table2;`

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
