While migrating my application from DB2 to PostgreSQL. I want to migrate ROLLUP() function in PostgreSQL. Example: SELECT WEEK(SALES_DATE) AS WEEK, DAYOFWEEK(SALES_DATE) AS DAY_WEEK, SUM(SALES) AS UNITS_SOLD FROM SALES GROUP BY ROLLUP ( WEEK(SALES_DATE), DAYOFWEEK(SALES_DATE) ) ORDER BY WEEK, DAY_WEEK This example shows two simple ROLLUP queries followed by a query which treats the two ROLLUPs as grouping sets in a single result set and specifies row ordering for each column involved in the grouping sets. How can I migrate ROLLUP() function in PostgreSQL? or is there any similar function in PostgreSQL which can done this job? -- View this message in context: http://postgresql.1045698.n5.nabble.com/Migration-from-DB2-to-PostgreSQL-ROLLUP-tp5759825.html Sent from the PostgreSQL - general mailing list archive at Nabble.com. -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
