Is it possible to make this SQL query faster?

Question

I have this query, but its so slow... I think the NOT IN function is the part slowing me down

SELECT ID  
FROM APPL  
WHERE TRIM(RCNL_ID) = XXX.20191102' AND ID NOT IN  
(
    SELECT ID  
    FROM HIST  
    WHERE SUBSTR(ID, 12, 1) = '9' AND TRAN_STATUS = 'REOK'  
)  
ORDER BY ID;  

It takes a while to run like 50-60 second is there a clever way to rewrite this so its faster?

Answer 1

Try using a materialised view(mv) or an index..? https://oracle-base.com/articles/misc/materialized-views

CREATE MATERIALIZED VIEW your_mv
PCTFREE 5
BUILD IMMEDIATE
REFRESH FORCE
ENABLE QUERY REWRITE
as
SELECT ID  
FROM APPL  
WHERE TRIM(RCNL_ID) = XXX.20191102' AND ID NOT IN  
(
    SELECT ID  
    FROM HIST  
    WHERE SUBSTR(ID, 12, 1) = '9' AND TRAN_STATUS = 'REOK'  
)  
ORDER BY ID;

Try using function based indexes
