Null As Default Value For Yes/no Field
Thank you for taking the time to report an issue.
What's wrong... Please write below.
I need to convert that field to a date/time one. Which is being hindered by these values of NULL.
The problem is that when I put the word NULL in the field criteria spot, Access believes that I am referring to a value of 'null' and will not do the update.
I have done "NULL", NULL, =NULL, ="NULL", is NULL. and no success.
Please remember that the actual value is not 'null'. It is a text field that has the word NULL in the field.
I've got an unbound combobox with a default value, but I still would like users to enter a Null value. I've got the Null value in the list of drop down items, but when it is selected, the combox value does not go to null, but instead goes to the default value.
Any easy way to allow null values to be selected? I know it was possible with older versions of Access, but not any more.
Which the makes
INSERT INTO ticketchanges VALUES (NULL,46,DEFAULT,'few af ae a',NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL,2);
The only thing I can think of is that I'm not declaring the column names because as you can see by the code, it's rather dynamic. So.
When I go to a new record, my textbox is Null. I've tried with the equals sign and without the equals sign and both result in a Null value in the textbox.
I can type ?Environ("Username") in the immediate window and I get the expected result (my network username).
I can set the default value for the textbox in the On Current event and it works fine, just wondering why I can't use the default value field in the property sheet to do this. Other functions such as =Date() work fine in the default value field.
Any idea why this might not be working
Field1 = Bldg Name (maybe null)
Field2 = Street
Field3 = Floor (maybe null)
Field4 = Room (maybe null)
Field5 = City
My problem is that in front of [Floor] should be "FL:" only if that field is not null. However, I keep getting the "FL:" in front of everything. How do I not include that when that specific field is null?
What I did is I created a field in table called Child1Gender with yes/no button which I changed value to Boy/Girl using ;"Boy";"Girl" as a format with combobox which values are -1 and 0 as access assigns as default value for Yes/No option. On the form I used bound multicheckbox which values are boy=-1 i.e. yes default value and Girl = 0 i.e.
No default value as access assigns. When I run table it fills all the ChildGender fields with no = 0 (Girl) as a default value. I wanted to make my default value as null so that people can select Child gender.
I've tried many different things to capture the Null entry and convert it using the Nz() function, but I can't get rid of it!
How can I trap this standard message and automatically insert a 0 in lieu of the null as the field is updated?
using either a validation rule or an event procedure.
I tried setting the field, in the properties, with a default value; but it would not take it.
I want to have a field (field 3) auto-populate based on what is entered into two other fields (field 1 & field 2).
Field 1 is a date field (when a presentation is due). Field 2 is a yes/no checkbox (if checked, it means no presentation is necessary). Field 3 would be a calculated text field (?) because text cannot be entered into Field 1.
If field 1 is null and field 2 is checked, then I want "NA" to auto populate into field 3. However, if field 1 is null and field 2 is not checked, I want "TBD" to auto populate into field 3. If field 1 is not null, then I want field 3 to be null
