I try to get a list of distinct name from the query below:

Select distinct [rodnee_WISDAssetsInvRemedy].[CI_NAME], ROW_NUMBER() OVER ( Order By [rodnee_WISDAssetsInvRemedy].[CI_NAME] Asc  ) as 'RowNum'
FROM rodnee_WISDAssetsInvRemedy

but it only gave me duplicated names.
104LMWC                      1
104LMWC                      2
ADMHXP01      3
ADMHXP01      4
AIBSFIBCPAPP1      5
AIBSFIBCPAPP1      6
AIBSFIPRODAPP1      7

why not simply

Select [rodnee_WISDAssetsInvRemedy].[CI_NAME], ROW_NUMBER() OVER ( Order By [rodnee_WISDAssetsInvRemedy].[CI_NAME] Asc  ) as 'RowNum'
FROM rodnee_WISDAssetsInvRemedy
group by [rodnee_WISDAssetsInvRemedy].[CI_NAME]
