For example, if resource pool A uses 40 cores and resource pool B uses 5 cores, switching a job from pool A to pool B will execute the job on the 5 cores of pool B.

Ensure that the jobs being switched are in the same state, such as all queuing or all running. If switching between different types of statements, it is recommended to switch them twice. Switching them together may exceed the concurrent statement limit, causing abnormal job wake-ups.<div class="codecoloring" codetype="Sql" id="EN-US_TOPIC_0000001764516410__screen689114128158"><div class="highlight"><table class="highlighttable"><tr><td class="linenos"><div class="linenodiv"><pre><span class="normal">1</span></pre></div></td><td class="code"><div><pre><span></span><span class="k">SELECT</span><span class="w"> </span><span class="n">gs_switch_respool</span><span class="w"> </span><span class="p">(</span><span class="n">queryid</span><span class="p">,</span><span class="s1">'xxx'</span><span class="p">)</span><span class="w"> </span><span class="k">FROM</span><span class="w"> </span><span class="n">xxx</span><span class="w"> </span><span class="k">where</span><span class="w"> </span><span class="n">xxx</span><span class="p">;</span>
