Date Only format with BCS

Question

I have created an External Content Type through SharePoint Designer. One of the fields that I'm getting from my database is a DateTime column. In SharePoint, however, I want to format this as a Date only. At the moment it's coming through as

2011-05-06 00:00:00z

I want something like:

2011-05-06

Or ideally:

06-05-2011

It sounds really simple, but I can find little information on how to achieve this. Have I missed something really obvious? Is this achievable? I do not want to have to modify the database (that will take time and administration)

EDIT: the particular problem is a date column within the External Data Picker, and the External Content type is only being used for an External Data column.

There is an article in the DUET info on MSDN that shows you how to do this: http://msdn.microsoft.com/en-us/library/gg271157.aspx

I think you can do it as follows as well (since an external content type is still a content type; however I have not tested this): - Create your external list from the external content type - Go into the external lists you have created for your site in sharepoint designer - In the right hand corner you can see the views. Your external list should have a default view. Click on it and the file should open in sharepoint designer.

Look for a snippet like this:

<XmlDefinition>
            <View Name="{62A0ABCF-DF9D-45DD-985E-46ECDC9F5004}" DefaultView="TRUE" MobileView="TRUE" MobileDefaultView="TRUE" Type="HTML" DisplayName="SmartAppList" Url="/Lists/ghjghj/ReadList.aspx" Level="1" BaseViewID="1" ContentTypeID="0x" ImageUrl="/_layouts/images/generic.png">
                <Method Name="ReadList"/>
                <Query>
                    <OrderBy>
                        <FieldRef Name="Id"/>
                    </OrderBy>
                </Query>
                <ViewFields>
                    <FieldRef Name="Id" ListItemMenu="TRUE" LinkToItem="TRUE"/>
                    <FieldRef Name="Name"/>
                    <FieldRef Name="Description"/>
                    <FieldRef Name="ConfigurationXml"/>
                </ViewFields>
                <RowLimit Paged="TRUE">30</RowLimit>
                <Aggregations Value="Off"/>
                <Toolbar Type="Standard"/>
            </View>
        </XmlDefinition

• At the fieldref for your field you should be able to add the format attribute. This allows you to change the display of the date/time field.

Refer to http://msdn.microsoft.com/en-us/library/aa543225.aspx for possible values.

Answer 2

From SharePoint designer:

List and Libraries -> Click on list -> Under Views tab -> Read List

Right click on the date field -> Edit formula

Replace:

$thisNode/@*[name()=current()/@Name]

With

substring-before($thisNode/@*[name()=current()/@Name], ' ')

It doesn't appear that this is possible at this time, which is annoying. Kudos for Roel for his tip on doing this for an External List.
