Execute Scalar to trap error in case of no records returned

Question

I have got this code below:

Dim lJobName As String = \"\"
SQLCommand.CommandText = \"Select JobName from Jobs where Id = @Id \"
SQLCommand.Parameters.Add(New         


        

Answer 1

I think it is possible to handle this situation in the statement of the query:

SELECT ISNULL(FieldID,"0") FROM TableName

and subsequently in the program validate the result:

if then ...... else ...... endif
