Convert all rows into different in sql server - sql

Question

I have a stored procedure that is showing a list of doctors and their details based on the sub-department they belong to. Below is the stored proc:
CREATE PROCEDURE SP_BILL_FOOTER_DOCTOR
#subDepartmentId int
AS
BEGIN
SELECT HETC_MST_EMPLOYEE.EMPLOYEE_NAME,
HETC_PAR_EMPLOYEE_TYPE.EMPLOYEE_TYPE_NAME,
HETC_MST_DOCTOR_SPECIALITY.DOCTOR_SPECIALITY_DESCRIPTION,
HETC_MST_SUB_DEPARTMENT.SUB_DEPARTMENT_NAME,
HETC_MST_EMPLOYEE.DOCTOR_SIGNATURE,
CASE WHEN HETC_MST_EMPLOYEE.DOCTOR_SIGNATURE = ''
THEN ''
ELSE ISNULL(SIGNATURE_PATH.DOCUMENT_PATH,'')+ HETC_MST_EMPLOYEE.DOCTOR_SIGNATURE
END AS DOCTOR_SIGNATURE_PIC
FROM HETC_MST_EMPLOYEE
INNER JOIN HETC_PAR_EMPLOYEE_TYPE
ON HETC_PAR_EMPLOYEE_TYPE.EMPLOYEE_TYPE_ID = HETC_MST_EMPLOYEE.EMPLOYEE_TYPE_ID
INNER JOIN HETC_MST_DOCTOR_SPECIALITY
ON HETC_MST_DOCTOR_SPECIALITY.DOCTOR_SPECIALITY_ID = HETC_MST_EMPLOYEE.DOCTOR_SPECIALITY_ID
INNER JOIN HETC_MST_DOCTOR_DEPARTMENT
ON HETC_MST_DOCTOR_DEPARTMENT.EMPLOYEE_ID = HETC_MST_EMPLOYEE.EMPLOYEE_ID
INNER JOIN HETC_MST_SUB_DEPARTMENT
ON HETC_MST_SUB_DEPARTMENT.SUB_DEPARTMENT_ID = HETC_MST_DOCTOR_DEPARTMENT.SUB_DEPARTMENT_ID
LEFT JOIN (SELECT DOCUMENT_PATH
FROM HETC_MST_DOCUMENT_PATH
INNER JOIN HETC_MST_TYPE_OF_ATTACHMENT
ON HETC_MST_DOCUMENT_PATH.TYPE_OF_DOCUMENT_ID = HETC_MST_TYPE_OF_ATTACHMENT.TYPE_OF_DOCUMENT_ID
WHERE HETC_MST_TYPE_OF_ATTACHMENT.TYPE_OF_DOCUMENT_CODE='DSI') AS DOC_SIGNATURE_PIC
ON 1=1
WHERE HETC_MST_SUB_DEPARTMENT.SUB_DEPARTMENT_ID = #subDepartmentId
END
Below is the link of the output that follows when procedure executes :
I want to know is it possible to convert the rows in different column. Like the output has 6 columns and 2 rows, I want all the data in 1 row with 12 columns. Below is the sample output:
It would be of great help if somebody could guide me on how to do it. I have understood that by using Pivot in Sql, I can achieve this, but none I have found to my specific case.

Answer 1

Please have a look at updated code below:
select *, row_number() over(order by employee_name) rownum into #a from (
SELECT HETC_MST_EMPLOYEE.EMPLOYEE_NAME,
HETC_PAR_EMPLOYEE_TYPE.EMPLOYEE_TYPE_NAME,
HETC_MST_DOCTOR_SPECIALITY.DOCTOR_SPECIALITY_DESCRIPTION,
HETC_MST_SUB_DEPARTMENT.SUB_DEPARTMENT_NAME,
HETC_MST_EMPLOYEE.DOCTOR_SIGNATURE,
CASE WHEN HETC_MST_EMPLOYEE.DOCTOR_SIGNATURE = ''
THEN ''
ELSE ISNULL(SIGNATURE_PATH.DOCUMENT_PATH,'')+ HETC_MST_EMPLOYEE.DOCTOR_SIGNATURE
END AS DOCTOR_SIGNATURE_PIC
FROM HETC_MST_EMPLOYEE
INNER JOIN HETC_PAR_EMPLOYEE_TYPE
ON HETC_PAR_EMPLOYEE_TYPE.EMPLOYEE_TYPE_ID = HETC_MST_EMPLOYEE.EMPLOYEE_TYPE_ID
INNER JOIN HETC_MST_DOCTOR_SPECIALITY
ON HETC_MST_DOCTOR_SPECIALITY.DOCTOR_SPECIALITY_ID = HETC_MST_EMPLOYEE.DOCTOR_SPECIALITY_ID
INNER JOIN HETC_MST_DOCTOR_DEPARTMENT
ON HETC_MST_DOCTOR_DEPARTMENT.EMPLOYEE_ID = HETC_MST_EMPLOYEE.EMPLOYEE_ID
INNER JOIN HETC_MST_SUB_DEPARTMENT
ON HETC_MST_SUB_DEPARTMENT.SUB_DEPARTMENT_ID = HETC_MST_DOCTOR_DEPARTMENT.SUB_DEPARTMENT_ID
LEFT JOIN (SELECT DOCUMENT_PATH
FROM HETC_MST_DOCUMENT_PATH
INNER JOIN HETC_MST_TYPE_OF_ATTACHMENT
ON HETC_MST_DOCUMENT_PATH.TYPE_OF_DOCUMENT_ID = HETC_MST_TYPE_OF_ATTACHMENT.TYPE_OF_DOCUMENT_ID
WHERE HETC_MST_TYPE_OF_ATTACHMENT.TYPE_OF_DOCUMENT_CODE='DSI') AS DOC_SIGNATURE_PIC
ON 1=1
WHERE HETC_MST_SUB_DEPARTMENT.SUB_DEPARTMENT_ID = #subDepartmentId )a
declare #iterator int=1
declare #string varchar(max)= ''
declare #string2 varchar(max)= ''
declare #string3 varchar(max)= ''
declare #string4 varchar(max)= ''
declare #exec varchar(max)
while #iterator<=(select max(rownum) from #a)
begin
select #string2=
'['+cast(#iterator as varchar(max))+'].'+ 'EMPLOYEE_NAME'+
',['+cast(#iterator as varchar(max))+'].'+'EMPLOYEE_TYPE_NAME' +
',['+cast(#iterator as varchar(max))+'].'+'DOCTOR_SPECIALITY_DESCRIPTION' +

from #a where rownum=#iterator
select #string= #string+#string2
select #string4=
case when #string4='' then

select #string3= case when #iterator>1 then #string3+' cross join #a ['+ cast(#iterator as varchar(max))+']' else '' end
set #iterator=#iterator+1
end
select #exec = 'select distinct'+ left(#string, len(#string)-1) +' from #a [1] '+#string3+ ' where '+ #string4
exec(''+#exec+'')

This isn't really an answer but a demonstration of how much using aliases can improve the legibility of your queries. Believe it or not this EXACTLY the same thing you posted. I just used aliases so you can read this instead of looking at a wall of text. The only actual change was to use a cross join instead of a left join on 1 = 1.
SELECT e.EMPLOYEE_NAME,
et.EMPLOYEE_TYPE_NAME,
s.DOCTOR_SPECIALITY_DESCRIPTION,
sd.SUB_DEPARTMENT_NAME,
e.DOCTOR_SIGNATURE,
CASE WHEN e.DOCTOR_SIGNATURE = ''
THEN ''
ELSE ISNULL(SIGNATURE_PATH.DOCUMENT_PATH, '') + e.DOCTOR_SIGNATURE
END AS DOCTOR_SIGNATURE_PIC
FROM HETC_MST_EMPLOYEE e
INNER JOIN HETC_PAR_EMPLOYEE_TYPE et ON et.EMPLOYEE_TYPE_ID = e.EMPLOYEE_TYPE_ID
INNER JOIN HETC_MST_DOCTOR_SPECIALITY s ON s.DOCTOR_SPECIALITY_ID = e.DOCTOR_SPECIALITY_ID
INNER JOIN HETC_MST_DOCTOR_DEPARTMENT dd ON dd.EMPLOYEE_ID = e.EMPLOYEE_ID
INNER JOIN HETC_MST_SUB_DEPARTMENT sd ON sd.SUB_DEPARTMENT_ID = dd.SUB_DEPARTMENT_ID
cross join
(
SELECT DOCUMENT_PATH
FROM HETC_MST_DOCUMENT_PATH p
INNER JOIN HETC_MST_TYPE_OF_ATTACHMENT a ON p.TYPE_OF_DOCUMENT_ID = a.TYPE_OF_DOCUMENT_ID
WHERE a.TYPE_OF_DOCUMENT_CODE='DSI'
) AS DOC_SIGNATURE_PIC
WHERE sd.SUB_DEPARTMENT_ID = #subDepartmentId
For the question at hand it is hard to tell what you are really wanting here. Maybe some conditional aggregation in combination with ROW_NUMBER. Or a PIVOT. You would need to post more details for this. Here is a great place to start. http://spaghettidba.com/2015/04/24/how-to-post-a-t-sql-question-on-a-public-forum/
