Why it is not converting the data type of the column, the initial datatype of the column is DT_STR
(DT_I8)(ISNULL(Column_Name) ? (DT_I8)NULL(DT_I8) : (DT_I8)Column_Name)
But still I am getting DT_STR as an ouput parameter

I know it seems redundant converting to a DT_STR even though you know it’s already a DT_STR but SSRS can be finicky:
I did this in a derived column with both your way and my way coming from a DT_STR field that stored numbers and managed to get an eight-byte signed integer.
Hope this helps!
