Question

ben bu sorguyu çalıştı

, bu hata var

select 
    (A.StudentId), 
    max(A.StudentFirstName), 
    max(A.StudentLastName), 
    max(A.StudentAddress), 
    'Batch ' + max(C.BatchName), 
    CAST(MAX(CAST(A.StudentStatus as INT)) AS BIT), 
    max(B.StudentBatchId) 
from 
    tblStudentDetails A 
inner join 
    tblStudentBatchDetails B on A.StudentId = B.studentid 
inner join 
    tblBatch C on C.BatchId = B.batchid 
where 
    max(A.StudentFirstName) like 'A%' 
group by 
    A.StudentId 

:

An aggregate may not appear in the WHERE clause unless it is in a subquery contained in a HAVING clause or a select list, and the column being aggregated is an outer reference.

birisi yardım bu sorunu kurtarmak için mi?

Answer 1

doğru sözdizimi olurdu ...

select (A.StudentId),max(A.StudentFirstName), 
max(A.StudentLastName),max(A.StudentAddress), 
'Batch ' + max(C.BatchName),CAST(MAX(CAST(A.StudentStatus as INT)) AS BIT), 
max(B.StudentBatchId) 
from tblStudentDetails A 
inner join tblStudentBatchDetails B on A.StudentId=B.studentid 
inner join tblBatch C on C.BatchId=B.batchid 
group by A.StudentId 
having max(A.StudentFirstName) like 'A%'
