title: SQL Select Unique Rows
body: <p>Example1:</p>
  
  <pre><code>IDENT | CURRENT | SOURCE
  12345 | 12345   | A
  23456 | 12345   | B
  34567 | 12345   | C
  </code></pre>
  
  <p>Example2:</p>
  
  <pre><code>IDENT | CURRENT | SOURCE
  56789 | 56789   | A 
  </code></pre>
  
  <p>Table with 3 columns, IDENT, CURRENT and SOURCE. I'm trying to write a query that will only display * on records where
  there are only one unique CURRENT record and IDENT = CURRENT (EXAMPLE 2). There are records that have the same CURRENT but different IDENT (Example 1),
  these records should be omitted from the results.</p>
  
  <p>All current queries I'm trying where IDENT=CURRENT is displaying results similar to EXAMPLE 1. Not sure if I need somehow use WHERE CURRENT COUNT = 1. </p>
