    When i use the store procedure "sp_spaceused TableX", it will show me the messages like:
    name: TableX
    reserved:30192 kb
    data:19552 kb
    index_size:10448 kb
    unused:1024000 kb
    How can i reclaim the unused space to the OS ?

    Thanks jagblue
    I executed than command DBCC CLEANTABLE , but it did not work.
    May be the only method is moving the rows to another table, then trancate the table, and move the rows into it.
