Distinct help

  • Hi all,

    I need a little help here. I have a table with duplicate agentcodes and agentnames.

    I need to select distinct agentcodes, and also a agentname. The agentname just has to have the agentcode.

    agentcode agentname

    1 Nolrick1

    1 Nolrick2

    1 Nolrick3

    So I want to have the distinct agentcode but the name would be one of the 3 names above.

    Thanks

    KS.

  • I'm a little confused.

    Do you mean you want your results to be:

    agentcode agentname

    1 Nolrick1

    Or does it not matter which agentname is returned? Or do you want it without the trailing number? Please post your expected results, and possibly a few more rows of sample data so we can verify.

  • usually you'll find the ROW_NUMBER function will do the trick for you here;

    uncomment out the outer SELECT to limit it to just one row, i left the full results as an example so you cna see what it is doing:

    /*

    --results

    RWagentcodeagentname

    11Nolrick1

    21Nolrick2

    31Nolrick3

    */

    with myExampleCTE as

    (SELECT 1 as agentcode, 'Nolrick1' as agentname UNION ALL

    SELECT 1 as agentcode, 'Nolrick2' as agentname UNION ALL

    SELECT 1 as agentcode, 'Nolrick3' as agentname

    )

    --SELECT * FROM (

    SELECT

    ROW_NUMBER() OVER (PARTITION BY agentcode ORDER BY agentcode,agentname) AS RW,

    agentcode,

    agentname

    FROM myExampleCTE

    --) X WHERE RW = 1

  • Ideally I would want my results to be

    agentcode agentname

    1 Nolrick1

    But any name would be fine.

    agentcode agentname

    1 Nolrick1

    1 Nolrick2

    1 Nolrick3

    0000005NORDIC WAVE AB - STO

    0000005NORDICON SWEDEN

    0000005NORDIC WAVE AB - STO

    Ideal results would be

    1 Nolrick1

    0000005NORDICON SWEDEN

    But any of the names that correspond with the agentcode would be fine.

  • The sample Lowell sent works just fine.

    Thanks Lowell, and Derrick.
