Wildcard value and PreparedStatement

Hi. I am using a PreparedStatement for an order search class I am creating. I want to query a datetime field in one of my tables. If I key the statement "SELECT * FROM ORDERMASTER WHERE ActualShipDate = '%'" it works great. However, since I am using a PreparedStatement, I have to set this parameter using setDate(). Correct? How can I set this value to a wildcard character (%) if it is looking for a value of the date type?
Any help would be GREATLY appreciated!!

You should be able to use the setString() method instead. If the query you listed above executes successfully from a sql editor, then that should work.
I'm sure it depends on the db vendor, but for ours (Informix), we can always use setString() regardless of the datatype and the db will interpret it appropriately.

Thanks for the help. That worked.
Now I have another question. Here is my PreparedStatement:


I have everything working the way I want it for this search I am creating except for setting the parameter for the Actual Ship date.
The user can select the option to search for shipped and unshipped orders (which is where I used the wildcard character) and that works. They can also choose to just search only shipped orders, or only unshipped orders. This is where I am running into problems.
What do I set the parameter to, to weed out the records with valid ship dates? I am using a default date of 1900-01-01 in unshipped orders so I can't use null. I can't use the wildcard character because that will still bring back all of them.
Also, can I not use the LIKE keyword with any other value than the wildcard on a DateTime field? I do not get any results if I key in "1900%".
Any suggestions?
Thanks!
