It trades accuracy for performance, and may return a result that varies between executions. The order of inputs may have an effect on its output. This function is used in conjunction with the summarize operator. Examples. The partition operator partitions the records of its input table into multiple subtables according to values in a key column. The operator runs a subquery on each subtable, and produces a single output table that is the union of the results of all subqueries. This operator is useful when you need to perform a subquery only on a subset ... Discussion: Use the UNION ALL clause to join data from columns in two or more tables.

In relational algebra (which SQL isn't) the union result might be one row, though only if the two input relations contained an identical tuple, eg. self-union of a one-tuple relation. – Robert Monfera. In this article. A view is a virtual table based on the result-set of a Kusto Query Language (KQL) query. Like real tables, views organize data with rows and columns, and participate in tasks that involve wildcard table name resolution, such as union * and search * scenarios. However, unlike real tables, views don't maintain dedicated data storage.
