Date and Time Format in SSIS - sql-server

Question

I have a date and time format:
Interval Start Time
1/13/16 1:30:00
1/15/16 10:30:00
Desired Result
Interval Start Time
13/01/2016 13:30:00 (24 Hr)
15/01/2016 10:30:00
The Interval Time is between 08:00 to 17:30.
I would like it to be: 13/01/2016 13:30 and 15/01/2016 10:30:00 and I devised this In SSIS derived Column:
(DT_DATE)(SUBSTRING([Interval Start Time],3,2) + "-" +
SUBSTRING([Interval Start Time],1,1) + "-" +
SUBSTRING([Interval Start Time],6,2) + " " +
SUBSTRING([Interval Start Time],9,1) == 1 ? "13" :
SUBSTRING([Interval Start Time],9,1) == 2 ? "14" :
SUBSTRING([Interval Start Time],9,1) == 3 ? "15" :
SUBSTRING([Interval Start Time],9,1) == 4 ? "16" :
SUBSTRING([Interval Start Time],9,1) == 5 ? "17" :
"[Interval Start Time]" )
+ ":" + SUBSTRING([Interval Start Time],11,2))
The error I get in SSIS is:
...The expression might contain an invalid token, an incomplete token, or an invalid element...
and I am not sure if the formula is correct in what I want it to do either. Any help would be much appreciated.

Answer 1

Before present a possible solution here, I want you be aware about some errors in your approach. Using expressions for this requeriment is very complex and hard to maintain, besides what happen when your Interval Start Time column have dates from October (10) to December (12) months, your string lenght will change and your hardcoded solution via SUBSTRING calls will return absurd data and produce error while package is running.
SOLUTION: Use Script component.
After creating your source, add a Script Component and link the source to it.
Configure the Script component to include Interval Start Time column by selecting it in Input Columns tab.
Add an output column, name it as you want and choose database timestamp (DT_DBTIMESTAMP).
Go to Script tab, and press the Edit Script... button.
Use the below code to overwrite the Input0_ProcessInputRow function.
public override void Input0_ProcessInputRow(Input0Buffer Row)
{
/*
* Add your code here
*/
var str_timestamp = Row.IntervalStartTime.ToString();
string[] arr = str_timestamp.Trim().Split(' ');
string[] date = arr[0].Split('/');
string[] time = arr[1].Split(':');
string formatedDate = "20" + date[2] + "-" + date[0].PadLeft(2, '0') + "-" + date[1].PadLeft(2, '0');
int hour = Convert.ToInt32(time[0]);
int hour_24 = hour < 8 ? hour + 12 : hour;
formatedDate += " " + hour_24 + ":" + time[1] + ":" + time[2];
Row.MyColumn = Convert.ToDateTime(formatedDate);
}
In Row.MyColumn, replace MyColumn by the given name of your output column.
Save changes in Visual Studio and close the editor.
Now you can add a destination after the Script component and you will see the formatted IntervalStartTime as you need.
Let me know if this helps.
