I know I need to use the parse method of the DateTime but am unsure where or
exactly how to do it. I am trying to update a SQL database with an
unspecified amount of data and am passing in several columns whose datatype
is of type DateTime. Below is my code.

using System;

The SqlException message would have been useful to help diagnose the
problem.
From the insert command text, it looks wrong - maybe a cut and past error.
expecting INSERT INTO table(...) VALUES(...); SELECT ... FROM table
WHERE ...
not INSERT INTO table(...) SELECT ... FROM table VALUES(...)

I don't understand your question...parse the date? Are you getting a
error when you run your code...what is the error? I know that if yo
try to pass in a string, formatted in a date format to a DateTime o
SmallDateTime SQL field, i.e., "12/10/1999", SQL server will no
complain..
