title: Can I check if a table exists before join?
body: <p>I have the following problem. I have Table A and would like to join to table B if table B exists. Can this be done? I am only writing SQL in WorkBench to try achieve it.</p>
  
  <p>I am aware I cannot use the EXISTS option as I have tried typing it out but it prompts for an error.</p>
  
  <p>Any suggestions would be greatly appreciated.</p>
  
  <p>Thanks.</p>
