How to manipulate string

aah then fine i thought you are passing directly as insert statement with the value…if you are passing from a excel you can replace the value with for each row loop and a if condtion like
String.IsNullOrEmpty(row(“columnname”))
Then
row(“columnname”) = “Null”

But any how this will add as string only buddy… @smita.mobifly
I think nothing will work perfectly buddy, for more info look at this, even i verified
