SQL Server：匹配两个表并按正确列的顺序结果

Question

I have two tables JOB and EMP ; structure and values are like this:

CREATE TABLE JOB 
(
    JOBID SMALLINT UNIQUE NOT NULL,
    JOBNAME CHAR(15)
);

CREATE TABLE EMP
(
    EMPID SMALLINT, 
    JOBID SMALLINT, 
    SAL SMALLINT, 
    CITYID SMALLINT,
    YEAR SMALLINT,
    STATUS CHAR(1)
);

INSERT INTO JOB(JOBID, JOBNAME) 
VALUES (1, 'DEVELOPMENT'),
       (2, 'DEVELOPMENT'),
       (3, 'TESTING'),
       (4, 'TESTING'),
       (7, 'TESTING'),
       (9, 'RESEARCH'),
       (8, 'HR');

INSERT INTO EMP (EMPID , JOBID, SAL, CITYID, YEAR, STATUS) 
VALUES (100, 1, 1000, 10, 2015, 'A'),
       (200, 2, 2000, 10, 2015, 'A'),
       (300, 1, 2500, 20, 2015, 'A'),
       (400, 3, 1000, 10, 2016, 'A'),
       (500, 6, 3000, 10, 2015, 'E'),
       (600, 8, 1000, 30, 2015, 'A'),
       (700, 8, 2000, 10, 2015, 'E'),
       (800, 9, 1500, 10, 2015, 'A');

I want to display all jobname count and avg salaries; for the jobname if jobid's not exists then display 0

For the given input cityid , YEAR and STATUS ( Emp table), take all jobid for each jobname (from job table ) and match in Emp table, if exists display count (count of jobid present in Emp table) and avgsal else 0 for count and avgsal . And Sal is calculated based on Status . If Status is 'A' Sal goes to Status-A-Sal else Status-E-Sal . And for each matched ie non zero record put 'X' in another field

Output should be like this for Cityid 's 10 and 20 year 2015. Results should be displayed first for Status 'A' and then Status 'E'. Added status type field in result .

Cityid  Status-type jobname         count   STATUS      sal
--------------------------------------------------------------
10      STATUSA     development     2       X           1500
10      STATUSA     TESTING         0                   0
10      STATUSA     RESEARCH        1       X           1500 
10      STATUSA     HR              0                   0
10      total                       3                   0
10      STATUSE     development     0                   0
10      STATUSE     TESTING         0                   0
10      STATUSE     RESEARCH        0                   0 
10      STATUSE     HR              1        X          2000
10      total                       1                   2000

20      STATUSA     development     1        X          2500
20      STATUSA     TESTING         0                   0
20      STATUSA     RESEARCH        0                   0 
20      STATUSA     HR              0                   0
20      total                       1                   2500
20      STATUSE     development     0                   0
20      STATUSE     TESTING         0                   0
20      STATUSE     RESEARCH        0                   0 
20      STATUSE     HR              0                   0
20      total                       0                   0

How to bring the results one status after another ?

I've tried like this but its throwing

SELECT C.CITYID  AS CITYID,
           CASE WHEN P.STATUS ='A' THEN 'STATUSA' ELSE 'STATUSE' END AS STATUS_TYPE ,
           COALESCE(J.JOBNAME, 'TOTAL') AS JOBNAME,
           COUNT(CASE WHEN P.STATUS ='A' THEN P.CITYID END ) AS COUNT ,
           COALESCE(AVG(CAST(CASE WHEN P.STATUS = 'A' THEN P.SAL END AS DECIMAL(13,2)))/12 , 0) AS "AVG SAL",
           COUNT(CASE WHEN P.STATUS ='E' THEN P.CITYID END ) AS  COUNT  ,
           COALESCE(AVG(CAST(CASE WHEN P.STATUS = 'E' THEN P.SAL END AS DECIMAL(13,2)))/12 , 0) AS "AVG SAL"
    FROM JOB1 J
    CROSS JOIN 
            (SELECT DISTINCT CITYID 
                FROM EMP1  B WHERE CITYID = 10

            ) C
    LEFT JOIN EMP1 P ON P.JOBID = J.JOBID 
            AND  P.CITYID = C.CITYID and
            YEAR = 2015
        GROUP BY ROLLUP(C.CITYID,  J.JOBNAME );

ERROR: Column 'EMP1.STATUS' is invalid in the select list because it is not contained in either an aggregate function or the GROUP BY clause.

IF OBJECT_ID('tempdb..#JOB') IS NOT NULL
    DROP TABLE #JOB

CREATE TABLE #JOB
