    And the indexes have to be selective enough to be useful for a seek or you'll get scans. Same things apply to non-clustered indexes too.

    Hi All,

    I'm trying to bulk insert a pipe-delimited file with <CR><LF> as a row terminator. The problem is some fields may contain <CR><LF>. So, I've asked the client to...

    what do you mean by "mid-score"? Do you mean average or second largest score (from three possible ones)?

    The middle one. You're listing all the actual scores each...

    mid_score --may be NULL if only one test taken

    low_score --may be NULL if only one or two tests taken

  • RE: How to use values keyword as parameter of a function
