Note that analytic functions in Stream Analytics query language, unlike in T-SQL, are evaluated first. In Stream Analytics query language:
- Analytic functions can be used in any place in the query that a scalar function is allowed. For example, you can use analytic functions in WHERE clause, JOIN clause, or GROUP BY clause.
- Analytic function computations are performed over all the input events of the current query input, optionally you can limit analytic function to only consider events that match the partition_by_clause and when_clause.
- Analytic functions are not affected by predicates in WHERE clause, join conditions in JOIN clause, or grouping expressions in GROUP BY clause of the current query.
