title: Excel SQL data type mismatch
body: <p>I have this query</p>
  
  <pre><code>SELECT * 
  FROM [RawData$] 
  WHERE 'Temperature[°C]' &lt;= 100  
  </code></pre>
  
  <p>But at the execution I get this error:</p>
  
  <p><em>Data type mismatch in criteria expression.</em></p>
  
  <p>The data in this column is 100% integer so I guess there is no problem.</p>
  
  <p>Further this works fine:</p>
  
  <pre><code>SELECT * 
  FROM [RawData$] 
  WHERE 'Temperature[°C]'
  </code></pre>
  
  <p>I also tried this too but then I get no values at all:</p>
  
  <pre><code>SELECT * 
  FROM [RawData$] 
  WHERE 'Temperature[°C]' &lt;= '100'
  </code></pre>
  
  <p>Actually the final question would be:</p>
  
  <p>What query do i need to search a column which name is: Temperature[°C]</p>
  
  <p><code>[Temperature[°C]]</code><br><code>[Temperature[[]°C]]</code></p>
  
  <p>do not work.</p>
