            Your code seems fine. The issue is that when you compose two rotations with given Euler angles, then you don't simply get a rotation given by the sums of these angles.

            How to optimize an Oracle UNION ALL of two 3-sec queries that takes over 200 secs ... even with rownum
            Asked 2021-Apr-10 at 19:40

            I am working to further optimize the following query. I have already had a lot of success optimizing the query up to this point, but now I am looking for help from others for ideas. I appreciate your help.

            The following query takes over 200 seconds to complete yet the two individual WITH clause queries (receiving_1 and receiving_2) that make up the "UNION ALL" take less than 4 seconds each.

            • receiving_1 -- 58 recs in 3.4 secs; cost 295 (no UNION)
            • receiving_2 -- 0 recs in 3.8 secs; cost 295 (no UNION)
            • UNION ALL of 1+2 -- 58 recs in 203.1 secs; cost 300 (UNION ALL)

            I was hoping "rownum" would help optimize the "UNION ALL", but it did not. This attempt was based on a note from AskTom --> Files --> SQLTechniques.zip (between 61 and 72)

            When you have two queries that run light speed separately But not so together Generally a mixed “CBO/RBO” problem Use of RBO with a feature that kicks in the CBO Rownum can be a temporary fix till all things are CBO

            NOTE: One optimization that avoids this issue is embedded replacement parameters or cursor parameters that greatly reduce the rows at key points in the query. However, because I need to run this query through a database link against a read-only database, the following options are not available for this query.

            • dbms_sql over database link: query is too long; dbs_sql does not accept a lob over database link; also DBAs don't allow the running of any PL/SQL in the read-only database.
            • pipelined function: pipelined function has known bug over database link between 19c and 11g so fails
            • sys_refcursor via PL/SQL: cursors are not supported over database links
            • set parameter values in PL/SQL package and use them in view: not allowed to execute any code in read-only database (I am still bugging the DBAs to allow this. This might be my best hope if I am not able to optimize the below query to run as a view.)

            NOTE: In an attempt at providing a good test case with as little code as possible, the below SQL (4,584 chars, 88 line breaks) is a greatly simplified version of the actual SQL (93,683 chars, 2,014 line breaks) I am developing. The original SQL has already gone through several rounds of optimizations to bring the runtime down from over an hour to under 10 seconds. This latest challenge is that the SQL has to be rewritten as a view as opposed to a SQL file with embedded substitution parameters. The substitution parameters were key to the optimizations up to now. I am now refactoring the SQL to work as a view in Oracle 11gR2 to be called via a database link from Oracle 19c. A view has no parameters, obviously. The driving parameters (ledger, OU, period) will be WHERE clause conditions when querying the view.

            Big picture: The actual SQL under development is an amalgamation of 6 report queries that share a lot of duplicated code. My work is to convert all six source report queries into an efficient extract for importing into a new database schema for reconciliation purposes.

            As I don't know the underlying tables, their structure and their data, I can only guess. Having said that, I'd try the following things (not knowing if any of the steps are helpful or not!):

            1. remove the rownum from receiving_all

            2. add the where clause from the main query to each of the subqueries in receiving_all. The optimizer might be able to infer this, but I am not sure.

            3. change union all to union in receiving_all and remove the distinct from receiving_1 and receiving_2

            4. receiving_2 seems to be included in receiving_2?

            5. If 4. is not the case, I would combine both into a single query with WHERE UPPER(bq.JE_CATEGORY) = UPPER('Receiving') AND ( () OR () )

            6. I would try if UPPER(bq.JE_CATEGORY) can be avoided. Functions prevent index access.

            7. In case you can create tables, I'd unroll the values of gccs into two tables, one for segment_1, and another table for segment_2.

            8. If 7. is not an option, I'd add the hint select /*+ materialize */ gcc.code_combination_id to gcc.

            I'm very curious to see which suggestion has any positive impact...

The problem is that i always get a black screen. when i multiply the frag color output by 5 my screen become grey.
