Hi Sudhir

Please see below

SELECT

  INDEX_NAME,

  NUM_ROWS,

  ROWLEN,

  QUALITY

FROM

( SELECT

    SUBSTR(I.INDEX_NAME, 1, 20) INDEX_NAME,

    I.NUM_ROWS NUM_ROWS,

    SUM(TC.AVG_COL_LEN + 1) + 7 ROWLEN,

    I.LEAF_BLOCKS LEAVES,

    ROUND((SUM(TC.AVG_COL_LEN + 1) + 7) * I.NUM_ROWS /

      1000000, 0) NET_MB,

    ROUND(I.LEAF_BLOCKS * (8079 - 23 * NVL(I.INI_TRANS, 2)) *
