title: SQLite query returning "syntax error Unable to execute statement"
body: <p>I just updated one of my databases including the creation of a new table, AUTO_VERIFICATION. That table is created with the following query:</p>
  
  <pre><code>CREATE TABLE AUTO_VERIFICATION (stock text NOT NULL PRIMARY KEY, current_value double, last_high double, last_low double)
  </code></pre>
  
  <p>Later when trying to insert the first entry using the same kind of code I already used successfully to insert data in other tables, I get an error in the following way (this uses my app's custom error message):</p>
  
  <pre><code>Error in call to MShareDatabase::execQuery: near \"0.00\": syntax error Unable to execute statement (query: INSERT INTO AUTO_VERIFICATION (stock, current_value, last_high, last_low) VALUES ('CYRE3', 0.00, 0.00, 0.00)
  </code></pre>
  
  <p>I just can't understand this error! I already checked with other parts of the code where I create other tables and insert data into them and it's the same syntax. I also used one of these websites where you can check if your SQL syntax is fine and it returned OK to me.</p>
  
  <p>Could anybody please tell me what is the problem?</p>
  
  <p>I'm using SQLite with Qt 5.5 and just for the record all other database transaction functions in my code (quite a lot) are working fine.</p>
