数据透视表计数为零

Question

我有一张员工表，其中可能分配了 0 或 1 个许可证类型。当我执行数据透视时，所有许可证类型的返回计数均为 0。

按查询计数/分组

SELECT SHORTNM, Count(e.EmployeNumber)
FROM suprkron.EMPLOYEE_LICENSE_VW e
    INNER JOIN LICENSETYPE l ON l.LICENSETYPEID = e.LicenseID
    AND ACTIVESW = '1'
GROUP BY SHORTNM

按查询结果计数/分组

SHORTNM	License Count
Workforce_Manager	245
Workforce_Timekeeper_Employee	2531
Workforce_Professional_Employee	2522

详细查询

SELECT SHORTNM, e.EmployeNumber
FROM suprkron.EMPLOYEE_LICENSE_VW e
INNER JOIN LICENSETYPE l ON l.LICENSETYPEID = e.LicenseID
AND ACTIVESW = '1'

详细查询结果

SHORTNM	EmployeNumber
Workforce_Timekeeper_Employee	1
Workforce_Professional_Employee	1
Workforce_Timekeeper_Employee	2
Workforce_Professional_Employee	2
Workforce_Professional_Employee	3
Workforce_Manager	3
Workforce_Timekeeper_Employee	3

数据透视表查询

SELECT *
FROM
    (SELECT SHORTNM, e.EmployeNumber, e.EmployeeName
        FROM suprkron.EMPLOYEE_LICENSE_VW e
            INNER JOIN LICENSETYPE lON l.LICENSETYPEID = e.LicenseID
            AND ACTIVESW = '1') t
PIVOT (  Count  (SHORTNM)
FOR EmployeNumber in ([Workforce_Manager],[Workforce_Mobile_Employee], 
                      [Workforce_Timekeeper_Employee],[Workforce_Professional_Employee], 
                      [Workforce_Mobile_Manager])) as pVT

数据透视表查询结果

EmployeeName	Workforce_Manager	Workforce_Mobile_Employee	Workforce_Timekeeper_Employee	Workforce_Professional_Employee	Workforce_Mobile_Manager
Emp1	0	0	0	0	0
Emp2	0	0	0	0	0
Emp3	0	0	0	0	0

Answer 1

为枢轴指定正确的列

SELECT *
FROM
    (SELECT SHORTNM, e.EmployeeName
        FROM suprkron.EMPLOYEE_LICENSE_VW e
            INNER JOIN LICENSETYPE lON l.LICENSETYPEID = e.LicenseID
            AND ACTIVESW = '1') t
PIVOT (  Count  (SHORTNM)
FOR SHORTNM in ([Workforce_Manager],[Workforce_Mobile_Employee], 
                      [Workforce_Timekeeper_Employee],[Workforce_Professional_Employee], 
                      [Workforce_Mobile_Manager])) as pVT

pivot for 子句应该读作FOR column_with_values IN ([this],[list],[of],[values],[formatted],[like],[columns]) - 来自SHORTNM 列的值成为查询输出中的列，因此您必须确保([this],[list],[of],[values],[formatted],[like],[columns]) 是实际遇到的值的列表在SHORTNM
