this is my first time using oracle Database in the company and I encountered this problem.
SELECT w.TABLE_NAME tbl_nm,
MAX(CASE WHEN t.partition_range LIKE 'year' THEN SUBSTR((w.PARTITION_NAME),1, LENGTH(w.PARTITION_NAME)-4) ELSE concat(SUBSTR((w.PARTITION_NAME), 1, LENGTH(w.PARTITION_NAME)-6)) END) AS par_nm,
MAX(CASE WHEN t.partition_range LIKE 'year' THEN SUBSTR((w.PARTITION_NAME), LENGTH(w.PARTITION_NAME)-3,4) ELSE concat(SUBSTR((w.PARTITION_NAME), LENGTH(w.PARTITION_NAME)-5,6)) END) AS par_date,
t.partition_range par_range,
t.data_dir data_dir,
t.index_dir index_dir,
t.add_range add_range,
CASE WHEN t.partition_range LIKE 'year' THEN EXTRACT(YEAR FROM systimestamp) ELSE TO_CHAR(systimestamp, 'YYYYMM') END AS cur_date
FROM INFORMATION_SCHEMA.PARTITIONS w, t_partition_manage t
WHERE w.TABLE_NAME = t.TABLE_NAME
GROUP BY w.TABLE_NAME
when I Select tbl_nm
, par_nm
, par_date
, par_range
, data_dir
, index_dir
, add_range
, cur_date
from INFORMATION_SCHEMA.PARTITIONS
and t_partition_manage
,
there seem to be a problem around in MAX( ... )
and I don't know what is wrong...
This is the error code
00909. 00000 - "invalid number of arguments"
*Cause:
*Action:
and I'm using SQLDeveloper as a client.
There is a problem with concat
as it takes two parameters and You are passing only one parameter. Concat
is not required at all in your solution:
SUBSTR(w.PARTITION_NAME, 1, LENGTH(w.PARTITION_NAME)-6)
And
SUBSTR(w.PARTITION_NAME), LENGTH(w.PARTITION_NAME)-5,6)
Also, you need more columns in GROUP BY
as select can not use columns directly which are not in GROUP BY
clause or you can use aggregate function.
