I'm trying to print the text based on the column. My idea was union all the count on each occupation and use a case to display it. But I'm not sure what is wrong with this code. Getting a error as sCount is not in field list. Any help is appreciated.
SELECT CASE
WHEN Occupation = "doctor" THEN
CONCAT("There are a total of ", dCount, " " , Occupation, "s.")
WHEN Occupation = "singer" THEN
CONCAT("There are a total of ", sCount, " " , Occupation, "s.")
END
FROM (
SELECT * FROM (
SELECT COUNT(Occupation) AS dCount, Lower(Occupation) AS Occupation FROM OCCUPATIONS WHERE Occupation = 'Doctor'
UNION
SELECT COUNT(Occupation) AS sCount, Lower(Occupation) AS Occupation FROM OCCUPATIONS WHERE Occupation = 'Singer'
) AS s
) AS m;
// this didnt work either
SELECT CASE
WHEN Occupation = "doctor" THEN
CONCAT("There are a total of ", dCount, " " , Occupation, "s.")
WHEN Occupation = "singer" THEN
CONCAT("There are a total of ", sCount, " " , Occupation, "s.")
END
FROM (
SELECT COUNT(Occupation) AS dCount, Lower(Occupation) AS Occupation FROM OCCUPATIONS WHERE Occupation = 'Doctor'
UNION
SELECT COUNT(Occupation) AS sCount, Lower(Occupation) AS Occupation FROM OCCUPATIONS WHERE Occupation = 'Singer'
) AS m;
Are you trying something like this :
CREATE TABLE OCCUPATIONS (
Occupation varchar(100) );
INSERT INTO OCCUPATIONS VALUES ('doctor'),('doctor'),
('singer'),('singer'),
('doctor'),('doctor'),
('singer'),('singer'),
('doctor'),('singer'),
('singer'),('singer');
SELECT CASE
WHEN Occupation = "doctor" THEN
CONCAT("There are a total of ", tbl.dCount, " " , Occupation, "s.")
WHEN Occupation = "singer" THEN
CONCAT("There are a total of ", tbl.sCount, " " , Occupation, "s.")
END as total_count
FROM (
SELECT COUNT(Occupation) AS dCount,null as sCount, Lower(Occupation) AS Occupation
FROM OCCUPATIONS
WHERE Occupation = 'doctor'
group by Occupation
union
SELECT null as tst, COUNT(Occupation) AS sCount, Lower(Occupation) AS Occupation
FROM OCCUPATIONS
WHERE Occupation = 'singer'
group by Occupation
)
as tbl ;
Result based on my demo would be:
total_count
There are a total of 5 doctors.
There are a total of 7 singers.
