Hello, I'm trying to group the results of a query with case as follows:
select
case
when sal BETWEEN 0 and 100000 then 1
when sal BETWEEN 100001 and 200000 then 2
when sal BETWEEN 200001 and 300000 then 3
when sal BETWEEN 300001 and 400000 then 4
else 5 END AS "ESCALAO",
count(*) AS "QTD"
FROM EMP
GROUP BY ESCALAO
ORDER BY QTD DESC;
But without success. The error message that says:
ORA-00904: "SCALE": Invalid identifier 00904. 00000 - "% s: invalid identifier" * Cause:
* Action: Error on line: 10 Column: 10
What is wrong with the query?
