Query to display tablespace (PSAPBTABD) table

Question

Experts,
We need to take the list of tables only in "PSAPBTABD" tablespace with following requirements.
NUM_ROWS,
AVG_ROW_LEN ROWLEN,
BLOCKS,
We have query but it downloads common for tables.
SELECT * FROM
( SELECT
    SUBSTR(TABLE_NAME, 1, 21) TABLE_NAME,
    NUM_ROWS,
    AVG_ROW_LEN ROWLEN,
    BLOCKS,
    ROUND((AVG_ROW_LEN + 1) * NUM_ROWS / 1000000, 0)
NET_MB,
    ROUND(BLOCKS * (8000 - 23 * INI_TRANS) *
      (1 - PCT_FREE / 100) / 1000000, 0) GROSS_MB,
    ROUND((BLOCKS * (8000 - 23 * INI_TRANS) * (1 - PCT_FREE/ 100) -
      (AVG_ROW_LEN + 1) * NUM_ROWS) / 1000000) "WASTED_MB"
  FROM DBA_TABLES
  WHERE
    NUM_ROWS IS NOT NULL AND
    PARTITIONED = 'NO' AND
    (IOT_TYPE != 'IOT' OR IOT_TYPE IS NULL)
  ORDER BY 7 DESC)
WHERE ROWNUM <= 10;
Please let us know how to query a particular tablespace table only
Thanks

Hi,
I do not know where you copy your query, but you may try to understand it and then you would find your answer.
The documentation is your friend
SELECT * FROM
( SELECT
"BBABLABLA"
FROM
                                      DBA_TABLES
WHERE
NUM_ROWS IS NOT NULL AND
PARTITIONED = 'NO' AND
(IOT_TYPE != 'IOT' OR IOT_TYPE IS NULL)
ORDER BY 7 DESC)
WHERE ROWNUM <= 10;
you are selecting from DBA_TABLES
what are the columns of this view? clue, look at the documentation
There is a column called "TABLESPACE_NAME" ....
Then you can put a condition very easily to show ONLY one tablespace
