title: Joining two similar tables in MySQL
body: <p>I have two tables with similar columns - let's say table A with column LABEL_A
  and table B with column LABEL_B. The data types of LABEL_A and LABEL_B are same.</p>
  
  <p>How can I select LABELs from both tables in a single query? (So the the result of the query contains single column LABEL containing data from LABEL columns of both tables).</p>
  
  <p>EDIT: Can I use such UNION queries in a CURSOR?</p>
  
  <p>Thanks for answers.</p>
