SQL
`SAMPLE` Clause
<div id="rrdiagram10"></div>  
[The `SAMPLE` clause](#docs:sql:query_syntax:sample) allows you to run the query on a sample from the base table. This can significantly speed up processing of queries, at the expense of accuracy in the result. Samples can also be used to quickly see a snapshot of the data when exploring a data set. The `SAMPLE` clause is applied right after anything in the `FROM` clause (i.e., after any joins, but before the where clause or any aggregates). See the [Samples](#docs:sql:samples) page for more information.
