I have a column called "UP_DATE". When the code below trys to read "UP_DATE" I get the following
riders.UP_DATE = CDate(reader("UP_DATE").ToString)
error. Conversion from string "" to type date is not valid. It looks as its tring to convert time. here is the data I get. riders.UP_DATE #12:00:00 AM#. Anyone have a solution to how to fix this column
.
When i query the data in SQL server manegement it displays the date fine. I have other date fields and they convert ok.

What is this code and what does #12:00:00 AM# mean? That looks like data from Access or something.
The error message is however pretty self explanatory. Whatever is reading your table it is getting an empty string in reader("UP_DATE") which can't be cast to a datetime object in many languages. t-sql will convert an empty string to 1/1/1900 but .NET will throw an exception when parsing a date from an empty string.

Yes the data came from ACCESS. I imported to sql. Is their anyway I can convert the "UP_DATE" Column to the sql date type. If so could you give me an example query to do this.
Thanks

Not sure what datatype it is now or if everything in it will convert correctly but...
alter table MyTable
alter column MyColumn datetime
