| <div class="block">Call to a windowed aggregate function. |
| |
| <p>To create an <code>OverCall</code>, start with an <a href="RelBuilder.AggCall.html" title="interface in org.apache.calcite.tools"><code>RelBuilder.AggCall</code></a> (created |
| by a method such as <a href="RelBuilder.html#aggregateCall(org.apache.calcite.sql.SqlAggFunction,boolean,org.apache.calcite.rex.RexNode,java.lang.String,org.apache.calcite.rex.RexNode...)"><code>RelBuilder.aggregateCall(org.apache.calcite.sql.SqlAggFunction, boolean, org.apache.calcite.rex.RexNode, java.lang.String, org.apache.calcite.rex.RexNode...)</code></a>, <a href="RelBuilder.html#sum(org.apache.calcite.rex.RexNode)"><code>RelBuilder.sum(org.apache.calcite.rex.RexNode)</code></a> or <a href="RelBuilder.html#count(org.apache.calcite.rex.RexNode...)"><code>RelBuilder.count(org.apache.calcite.rex.RexNode...)</code></a>) |
| and call its <a href="RelBuilder.AggCall.html#over()"><code>RelBuilder.AggCall.over()</code></a> method. For example, |
| |
| <pre><code> |
| b.scan("EMP") |
| .project(b.field("DEPTNO"), |
| b.aggregateCall(SqlStdOperatorTable.ROW_NUMBER) |
| .over() |
| .partitionBy() |
| .orderBy(b.field("EMPNO")) |
| .rowsUnbounded() |
| .allowPartial(true) |
| .nullWhenCountZero(false) |
| .as("x")) |
| </code></pre> |
| |
| <p>Unlike an aggregate call, a windowed aggregate call is an expression |
| that you can use in a <a href="../rel/core/Project.html" title="class in org.apache.calcite.rel.core"><code>Project</code></a> or <a href="../rel/core/Filter.html" title="class in org.apache.calcite.rel.core"><code>Filter</code></a>. So, to finish, |
| call <a href="#toRex()"><code>toRex()</code></a> to convert the <code>OverCall</code> to a |
| <a href="../rex/RexNode.html" title="class in org.apache.calcite.rex"><code>RexNode</code></a>; the <a href="#as(java.lang.String)"><code>as(java.lang.String)</code></a> method (used in the above example) |
| does the same but also assigns an column alias.</div> |
