I'd like for the Default Value for a Number field in table designer to be blank upon creation rather than 0. I'd found the answer and changed it before years ago, but can't seem to find the info currently for Access 2013.
The only way to arrange this is setting the default value to Null in the corresponding table.
There's no such thing as an application setting that will arrange this for numeric fields.

My TDbgrid is displaying "1899/12/30 23:00" in a time field. I have connected the database via a dynamic link , so i cannot change anything via design. I am aware that there is solution to this on StackOverflow but i cannot use the solution because my database is connected dynamically. Is there a way to display the time only.
Thank you.
This is by design, as the "zero date" value of DateTime is Access in 1899-12-30.
Thus, your time value of your sample is 23:00:00.
However, a DateTime value carries no format, so the solution is up to you - apply the format you wish to the value whenever you wish to display the time - in your case, the format will most likely be hh:nn (in VBA, don't know about Delphi).
Building an ms access data base. I have one field called form type.
I have 4 forms pulling from this field. Currently I have a drop down stating Internal, External, Other, and Cases.
My co-workers select the wrong drop down item for the form they are using.
Is there a way to have multiple default values for a single field?
Or can the field be auto filled when submitted without the user selecting anything?
I tried no default value with a data validation drop down list. I have searched the web for alternative methods with no avail.
My expected result would include the form auto selecting the correct "Form Type" for the field. This way there is no user error.
Thanks for taking a look, Matt
As you have four different forms using the same table-field, you can put a different default value in each form for this control:
In the design view of each form select the combo box and then, if not already done, open the Property Sheet (e.g. with key F4).
Then put the proper default value in the property Default Value and you're done.

Is there a way to change the value of all the selected cells in an Access table to one, user specified value ? In Excel, this would be similar to selecting a set of cells in a column, changing the value of the first, then "Ctrl-Enter" to change the value in all the selected cells.
I was able to do something along these lines using "replace", but that only works if all the values being replaced are the same and the user is willing to click the replace button for every cell they want the replace to work on. It's a fair solution for this special case.
I can do what I want quite handily using sql. But the average user of this DB will not know SQL. Also, I kinda don't want them throwing SQL at the DB if they don't know what they are doing with SQL (so easy to destroy a lot using so little code).
If it's not that simple, I'd like to welcome any brainstorming on how to do this.
Looking through my database tables, I'm seeing that the created field is invariably being set as "0000-00-00 00:00:00". The modified field is being auto-populated by sensible dates.
It seems to me very strange that the automagic would get modified right but not created. As far as I can recall I haven't done anything that would unset the created field's value - e.g. specifying it somewhere. Are there any obvious CakePHP "gotchas" I may have fallen foul of that might have messed up my created field in some way?
The only thing I can find in the documentation is that the cakephp only controls this field if it is called "created" and is of type DateTime and the default value is set to NULL. Can you verify that all of this is true in your tables?
I'm recieving the following error on trying to run an append query in access.
Microsoft Office Access set .... and it didnt't add... 779280 records(s) due to validation rule violations.
If I choose to run the query anyways, nothing actually happens.
To give some context, I'm simply trying to copy a populated field, consisting of values similar to "16-2009-02, 34-2010-02, et cetera" to another currently unpopulated field.
The fields themselves have no set validation rules, and both have the standard text field options.
I'm hoping to be able to simply remove those hyphens, and fix the issue. But I guess that's what I'm not sure about, are those hyphens actually a problem?

Thanks in advance!
Does the destination field have Allow Zero Length set to false or Required set to true? If it does, it is possible that some of the data from the source column is null or is set to an empty string. In addition, you should verify that the field sizes on the new column is equal to larger than the source column.
EDIT On appending from one table to another, you must ensure that you populate the columns that makeup the primary key of the destination table. Thus, from your screenshot, you need to include the loggerid and datetime columns from the "Log ID" table. Now, if there are collisions, Access should tell you how many rows generated collisions and let you append the ones that did not collide with the uniqueness restriction on loggerid and datetime
Make sure the target column is not indexed or, if it is, that duplicates are allowed. Access often makes indexing decisions on your behalf and sometimes they are not correct.
