oracle - Oracle SQL 更新卡住了

Question

我正在使用这个查询：

UPDATE tbl_temp SET KEYVALUE =
(
   WITH PRIMARKY_KEYS AS (
          SELECT listagg(colvalue,'|') WITHIN GROUP (ORDER BY idcolumn) AS colvalues,idnum  
          FROM tmp_columns
          WHERE tmp_columns.columnname IN ('ID','IDSCHEME')
          GROUP BY idnum
   )
   SELECT colvalues FROM PRIMARKY_KEYS P
   WHERE tbl_temp.id_row = P.idnum
);

但它只是卡住了

tbl_temp 有这些列：

id_row number
test_env char(3)
tablename varchar2,
rowvalue  varchar2 ,
uniquekey varchar2
keyvalue varchar2

tmp_columns 有这些列：

idnum number
env varchar2
colvalue
idcolumn
columnname
