Answer 1

Use CONVERT and supply third parameter for date and time styles.

Try this:

select VisitID as Value, Convert(nvarchar(50),VisitID)+' - '+Convert(nvarchar(50),VisitDate, 101) as Text 
from Visit

Please try this:

SELECT 
 VisitID AS Value, 
 CONVERT(VARCHAR, VisitID, 20) + '-' + ISNULL(CONVERT(VARCHAR, VisitDate, 20), '') AS Text 
FROM Visit

SELECT
visitid [Value]
,(CAST(VisitID AS VARCHAR) + '-' _ CAST(VisitDate AS VARCHAR)) [Text]
FROM Visit
