Combining Date and Time in DTS To Make a DT_DBTIMESTAMP datetime

Brant Burnett — Tue, 25 Nov 2008 20:16:00 +0000

I was recently dealing with importing a DBISAM (Btrieve) database to SQL Server, which had separate date and time columns where I wanted to import a DateTime. Using the ODBC driver and a DataReader data source, it was returning the date as the DT_DBTIMESTAMP type and the time as a DT_I8 long integer.

I tried using the Derived Column transformation to combine them, but never could get it to work. There simply aren’t many date functions supported by the Derived Column formulas. Finally, I settled on using the following VBS script using the Script Component transformation:

If Not Row.StartDate_IsNull Then
    If Row.StartTime_IsNull Then
        Row.StartDateTime = Row.StartDate
    Else
        Row.StartDateTime = Row.StartDate.AddTicks(Row.StartTime)
    End If
End If

Creating GUID Derived Column in DTS

If you want to add a constant GUID to a table during a DTS transformation, it’s a little tricky. Here’s the solution.

Use the Derived Column transformation in order to add a new column. For the formula, use the GUID surrounded by double quotes. The trick is that you MUST include the curly braces, like so:

“{B83030CF-EC5A-45ca-BE2D-BCFCC2A85034}”

Then set the type of the column to unique identifier (DT_GUID). That’s it.
