I can think of at least two options… Or… Both let you have multiple different sets of constants. One is expandable without changing the schema, though the query still would need to change. The main advantage of either approach is that you can re-use the constants else where, but store them once in a centralised … Read more
RANK gives you the ranking within your ordered partition. Ties are assigned the same rank, with the next ranking(s) skipped. So, if you have 3 items at rank 2, the next rank listed would be ranked 5. DENSE_RANK again gives you the ranking within your ordered partition, but the ranks are consecutive. No ranks are … Read more

The keyword for Oracle PL/SQL is “ELSIF” ( no extra “E”), not ELSEIF (yes, confusing and stupid)
I’m mostly used to Apex 4.1, but this approach should work. You don’t need an LOV. Your report query should include both the MAST_ID and the TASK_NAME columns.

I read that it might be in But I checked there as well and there is even no mysql directory, only some postfix thing … Read more
WHERE clause introduces a condition on individual rows; HAVING clause introduces a condition on aggregations, i.e. results of selection where a single result, such as count, average, min, max, or sum, has been produced from multiple rows. Your query calls for a second kind of condition (i.e. a condition on an aggregation) hence HAVING works correctly. As a rule of thumb, use WHERE before GROUP BY and HAVING after GROUP BY. … Read more
To start with you can’t do this: The HAVING clause can only contain things which are attributes of the aggregate groups. In addition, 1, 2, 3 is not valid in GROUP BY in SQL Server – I think that’s only valid in ORDER BY. Can you explain why this isn’t what you are looking for:
