title: MySQL: Invalid GIS data provided to function st_geometryfromtext
body: <p>Here's my code:</p>
  
  <pre><code>SET @poly =
      'Polygon((-98.07697478272888 30.123832577126326,
                -98.07697478272888 30.535734310413392,
                -97.48302581787107 30.535734310413392,
                -97.48302581787107 30.123832577126326))';
  
  SELECT name
  FROM county_shapes
  WHERE MBRContains(ST_GeomFromText(@poly), SHAPE);
  </code></pre>
  
  <p>Whenever I run that I get a "MySQL: Invalid GIS data provided to function st_geometryfromtext" error.</p>
  
  <p>This returns the same error:</p>
  
  <pre><code>SELECT name
  FROM county_shapes
  WHERE MBRContains(ST_GeomFromText('Polygon((-98.07697478272888 30.123832577126326,
                -98.07697478272888 30.535734310413392,
                -97.48302581787107 30.535734310413392,
                -97.48302581787107 30.123832577126326))'), SHAPE);
  </code></pre>
  
  <p>Any ideas?</p>
