Default Getting Problem in DATE/TIME Data type in MS Acces


I am getting problem in DATE/TIME data type in MS Access data base using ASP forms, Following is the senario.

There are three DATE/TIME field in MS Access, Date1, Date2, Date3 and I have three text boxes in ASP, from where i am entering dates. If i enter only one date in one text box and rest of them are null and when i click on submit button then the insert into qurey will fire and then it give me an error "Data Type mismatch", insted of if i enter the three dates in text box it's accept the data and post into to database.

Rather then i write a check in ASP that if the text box is "" means Empty then it insert word "NULL" not "" in date/time field in database but again it's give me an error Data type mismatch because it's not acsept word NULL in date/time data type.

What would i do if don't want to enter date in rest of 2 Date/Time field??? because it's dosen't accepting word NULL or empty value in database.

   Date/Time data type could not accept null values. Other wise you insert default date if you dont want to enter date at input.

Or change the datatype of date field to text. Then it accepts any type of value.

In the insert statement, it cannot accept NULL in the date feidl.

Hi selam70,

Set the "Default Value" of Date/Time Field in table's design to some valid date values, for columns that you would wish to ignore entering values on the asp page. And when constructing INSERT statement, don't include those date/time columns that are not entered with values on the ASP page.

Changing the date/time to TEXT would result on other problems in future like comparing/calculating date/time values, also If time is involved for any such calculations, then you would have to manipulate separately or convert from string to date everytime calculcation is required. So I won't suggest you change the datatype.
