6.1.9.5 Configuring a Select CQL Construct

The Select Oracle CQL construct represents the Oracle CQL SELECT clause. For information on representing the WHERE clause, see Section 6.1.9.9, Configuring a Filter CQL Construct . The Select Oracle CQL construct editor provides a tab for each of the following sub-clauses: ■ select_clause : Use this clause to specify the stream elements to select from the stream or view you specify. See Figure 6–48, Query Wizard Select Editor Dialog: Project Tab . ■ opt_group_by_clause : Use this clause to specify optional grouping conditions your query applies to its results. See Figure 6–49, Query Wizard Select Editor Dialog: Group Tab . ■ opt_having_clause :Use this clause to restrict the groups of returned stream elements to those groups for which the specified condition is TRUE. If you omit this clause, then Oracle CEP returns summary results for all groups. See Figure 6–50, Query Wizard Select Editor Dialog: Condition Tab . ■ order_by_clause : Use this clause to specify optional ordering conditions your query applies to its results. See Figure 6–51, Query Wizard Select Editor Dialog: Order Tab .
