wk_units1-105는 열 이름 cnt_sls_dm.fct_sales_summary 테이블 이름입니다. 우리는 우리가 기능 다음 적용하는 PL/SQL에서 뭔가를 만들 필요가 짧은에서 b.fct_sales_summary

의 주 1
a.fct_sales_summary 의 같은 테이블 만 주 2에서 데이터를 비교하고 (나는 의식입니다)

훨씬 더 컴팩트하게 만들려면 테이블을 표준화하십시오. 당신이 좋아하는 이름 열이있을 때 :

wk_units1 
wk_units2 
wk_units3 
... 
wk_units48 
wk_units49 
wk_units50

을하면 필요할 경우 항상 우리가 PIVOT 쿼리에 대한 열 위치로 다시 당겨 수, 행에 사람들을 정상화 할 수 있습니다.

여기에 피벗 예제가 있습니다. http://www.adp-gmbh.ch/ora/samples/pivot.html 내 권장 사항은 귀하의 문제에 대한 테이블을 디자인하십시오. 테이블이 더 잘 설계되면 쿼리가 쉬워집니다. –
