DefaultExpression property of TField |
Wed, Oct 29 2008 2:42 PM | Permanent Link |
"Royke" | I don't think this works as intended: "Specifies an SQL expression that is
assigned to the field if the user does not provide a value." Is this functionality in place in EDB? (The Delphi 7 Help text is not very clear, btw. Is this what 'value' delivers when it is null in the table? Or does this value gets put into the table, if a null is found before post? Should I see this in a TDBEdit? Or just when I ask for a field's value?) Royke |

"Royke" | I misinterpreted the Help. Even when using the BDE, this value only shows up
when you create a new record. Pretty bad D7 Help text.

<< I don't think this works as intended: "Specifies an SQL expression that is assigned to the field if the user does not provide a value." Is this functionality in place in EDB? >> No, EDB defines the default values at the physical column level, and does not use the Delphi TDataSet/TField properties for default values. -- Tim Young Elevate Software www.elevatesoft.com |
