Julian Hyde commented on CALCITE-5955: -------------------------------------- Can you define in the doc what you mean by 'allows framing'? Give examples of functions that do and do not allow framing. If someone was to use a BigQuery percentile function and unparse it in a non-BigQuery dialect, what would happen? If someone uses a BigQuery percentile function in a query (using 'OVER' syntax), does it become an aggregate query? (Recall that in an aggregate query I cannot reference columns that are not being grouped.) > BigQuery PERCENTILE functions are unparsed incorrectly > ------------------------------------------------------ > > Key: CALCITE-5955 > URL: https://issues.apache.org/jira/browse/CALCITE-5955 > Project: Calcite > Issue Type: Bug > Reporter: Tanner Clary > Assignee: Tanner Clary > Priority: Major > Labels: pull-request-available > > Currently if you have a query like: > {{SELECT PERCENTILE_CONT(x, .5) OVER() FROM x;}} the {{OVER()}} clause gets > unparsed with a {{window frame clause}} which BigQuery defines > [here|https://cloud.google.com/bigquery/docs/reference/standard-sql/window-function-calls#def_window_frame]. > > From the docs: "Only aggregate analytic functions can use a window frame > clause." > This causes BigQuery to fail with the following error: {{Window framing > clause is not allowed for analytic function percentile_cont}} -- This message was sent by Atlassian Jira (v8.20.10#820010)
