thinkphp 3.1.2 About the method of printing sql statement

<code> M('user')->where('user_id = %d', $v['user_id'])->find()</code>

Excuse me, there is such a data query method in thinkphp3.1.2. How to print out the native sql statement it executes?

I read the wrong question

<code>echo  M("user")->getLastSql();</code>

M('user')->fetchsql(true)->where('user_id = %d', $v['user_id'])->find()
