title: Find out how many times function is used in database
body: <p>I had this function that was checking if some specific day is off day or not but it was not serving purpose well so I find out another way to check the day and it is working more efficiently than the function. I don't remember at how many places or in how many procedures/functions I have use this function in my database. Is there any way I can find out in which procedure or function I am using this function so I can change the query there as well so it might not affect the result?</p>
  
  <p>Function name is <code>fnIsOffDay</code>.</p>
