    <pre><code>Select ... From Table_B As B Left Join ( Select AB.id_B, A.id, A.status From Table_A_has_B As AB Join Table_A As A On A.id = AB.id_A Where A.status = 1 ) As Z On Z.id_B = B.id </code></pre> <p>This portion of the original post is not clear: <code>if a Table_B record hasn't any associated Table_A also should be selected.</code>. </p> <p>If you only want rows from Table_B then:</p> <pre><code>Select B.* From Table_B As B Where Exists ( Select 1 From Table_A_has_B As AB Join Table_A As A On A.id = AB.id_A Where A.status = 1 And AB.id_B = B.id ) </code></pre> <p>If you want rows from <code>Table_ B</code> where either there are no rows in <code>Table_A_has_B</code> for a given <code>id_B</code> or where if there are rows it must be associated with a Table_A item where <code>status</code> is 1, then :</p> <pre><code>Select B.* From Table_B As B Where Exists ( Select 1 From Table_A_has_B As AB Join Table_A As A On A.id = AB.id_A Where A.status = 1 And AB.id_B = B.id ) Or Not Exists ( Select 1 From Table_A_has_B As AB Where AB.id_B = B.id ) </code></pre> <p>If what you want is rows from Table_A but only where the status is 1 and for all others a null, then the first query I provided would be the solution. Providing us with some expected output results would obviously help tremendously.</p> <p><strong>Edit given update to OP</strong></p> <p>Given your update, which only now makes it clear what you are actually trying to achieve, you do the following:</p> <pre><code>Select B.id From Table_B As B Where Not Exists ( Select 1 From Table_A_has_B As AB Join Table_A As A On A.id = AB.id_A Where A.status &lt;&gt; 1 And AB.id_B = B.id ) </code></pre>

Querying!

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
