Hey everyone,
<div><br>
</div>
<div>Lets say you have an ets table with entries as shown below:</div>
<div><br>
</div>
<div>{table_name, key, {A, [B]}. </div>
<div><br>
</div>
<div>I am trying to delete all table entries matching A. I can create a match like so:</div>
<div><br>
</div>
<div>ets:match(table_name, {'_', '_', {Node, '$1'}}) </div>
<div><br>
</div>
<div>and it returns the values for B. But when I run match_delete or select_delete, I get a badarg error…:<br>
</div>
<div><br>
</div>

<div>
<div><br>
</div>
<div>So I tried to match and object and delete it...</div>

I would like to avoid re-creating the table structure, as it is not from a project that I created and would take some time to fix all the code. How do I delete something from this table?
<div><br>
</div>
<div>Thanks!<br>
