<p>The <codeph>KILL QUERY</codeph> statement allows you to programmatically terminate running
queries by specifying their query ids. This functionality helps manage workloads by enabling
users to cancel and unregister queries across any coordinator in the cluster.</p>
<p>
<b>Syntax:</b>
</p>
<codeblock id="codeblock_vjr_mry_52c">KILL QUERY '<varname>query_id</varname>';</codeblock>
<p>Replace '<varname>query_id</varname>' with the query id you want to terminate.</p>
<p><b>Example:</b></p>
<codeblock id="codeblock_jfk_sry_52c">KILL QUERY '123:456';</codeblock>
<p><varname>query_id</varname> represents a query that is currently executing in the system.</p>
<p><b>Required privileges</b>: Only administrators or query owners can execute <codeph>KILL
QUERY</codeph>.</p>
<p><b>Cancellation</b>: Cannot be cancelled.</p>
<p><b>Considerations</b>: If the specified query is not found on any of the coordinators in the
cluster, a <codeph>Could not find query on any coordinator</codeph> error is returned.</p>
