title: Maximum number of allowed datasets in one project
body: <p>Is there a limit on how many datasets I can create in one BigQuery project? I did not find this limit anywhere mentioned in documentations.</p>
  
  <p>I am asking this because I want to create a dataset per day. Under the daily dataset, there will be the same number of tables being created with the daily data. E.g.,</p>
  
  <pre><code>dataset_20121101
     - table1
     - table2
  dataset_20121102
     - table1
     - table2
  ...
  dataset_201XXXXX
     - table1
     - table2
  </code></pre>
  
  <p>Also if I want to do a query over a range of datasets, can I do something better than explicitly selecting from every single dataset? For instance,</p>
  
  <pre><code>select date, sum(price) from 
   dateset_20121101.table1, 
   dateset_20121102.table1,
   dateset_20121103.table1,
   dateset_20121104.table1
   group by date order by date
  </code></pre>
  
  <p>I guess not, but just try to confirm. </p>
  
  <p>Thanks. </p>
