    Hi Team,

     

    i want to avoid "??" in the result set but i am getting "??"

    can you please help on this.

    My Script:

    AllCountryStates

    (

    CountryName NVARCHAR(100),

    Treeid int

    )

    insert INTO #AllCountryStates

    select N'??',1

    select * from #AllCountryStates

    declare @Country NVARCHAR(1000)

    SELECT @Country = STUFF(

    (SELECT ',' + ''

    + ( CountryName ) + ''

    FROM (select c.CountryName,c.TreeId

    FROM #AllCountryStates c

    ) as CountryName order by TreeId

    FOR XML PATH(''), TYPE).value('.', 'VARCHAR(MAX)'),1,1,'' )

    ---Country End

    select @Country

    --Existing Result:

    ??

     

    Expected result:

    ??

    Please note that I hit 'Report' when I meant to hit 'Quote' and there seems to be no way of reversing that ... apologies.

    This makes no sense to me - your expected result is the same as the existing result and therefore no change is required:

    Existing Result:

    "??"

     

    Expected Result:

    "??"

    If the answer to your question can be found with a brief Google search, please perform the search yourself, rather than expecting one of the SSC members to do it for you.

    CREATE table #AllCountryStates

    (

    CountryName NVARCHAR(100),

    Treeid int

    )

    insert INTO #AllCountryStates

    select N'??',1

    select * from #AllCountryStates

    declare @Country NVARCHAR(1000)

    SELECT @Country = STUFF(

    (SELECT ',' + ''

    + ( CountryName ) + ''

    FROM (select c.CountryName,c.TreeId

    FROM #AllCountryStates c

    ) as CountryName order by TreeId

    FOR XML PATH(''), TYPE).value('.', 'VARCHAR(MAX)'),1,1,'' )

    ---Country End

    select @Country

    Change this, FOR XML PATH(''), TYPE).value('.', 'VARCHAR(MAX)'),1,1,'' ), to use NVARCHAR(MAX) in place of the VARCHAR(MAX).  The implicit change is causing you to lose the UNICODE values.

    Your problem is here:

    FOR XML PATH(''), TYPE).value('.', 'VARCHAR(MAX)'),1,1,'' )

    Your country names are NVARCHAR, but you are converting them to VARCHAR, so you are losing information that cannot be encoded in VARCHAR.
