Sql pivot子句中的Oracle计数值

我有下表：

身份证件 洛蒂普 PROID 储物柜 XXXXX 06 01 Y XXXXX 06 02 X XXXXX 06 02 s XXXXX 06 01 R XXXXX 02 01 Y XXXXX 02 02 X XXXXX 02 02 s XXXXX 02 01 R XXXXX 02 01 R XXXXX 02 01 R XXXXX 02 01 R YYYY 06 01 Y YYYY 06 02 X YYYY 06 02 s YYYY 06 01 R YYYY 02 01 Y YYYY 02 02 X YYYY 02 02 s YYYY 02 01 R 先数一数

SELECT *
FROM(
    SELECT id, title,
           LISTAGG(lockr,',') WITHIN GROUP (ORDER BY title) AS value
    FROM(
       SELECT id,lotyp||proid As title, case count(*) when 1 then '' else CAST(count(*) AS VARCHAR2(10)) end || LOCKR As LOCKR
       FROM  t
       GROUP BY id,lotyp||proid, LOCKR
   ) t
GROUP BY id, title )
PIVOT (
         MAX(value) FOR title IN ('0201' AS "0201",
                                  '0202' AS "0202",
                                  '0601' AS "0601",
                                  '0602' AS "0602"))   
ORDER BY id; 

先数一数
