title: How to limit BigQuery query size for testing a query sample through the web user-interface?
body: <p>I would like to know if it is possible to limit the bigquery query size when running a query through the web user-interface? </p>
  
  <p>My idea is just to test the query but instead of querying all my tables; I would like just to query a part of it with for instance a number of row.</p>
  
  <p>Limit is not optimizing my query cost, so the idea is to find a function similar to "row_number" or "fetch".</p>
  
  <p>Sorry I'm a marketer and not a developer, so thank you in advance for your kind help.</p>
