AsDate / TDate Field

Post by OlliWW » Fri 28 Jul 2017 21:47


In Microsoft SQL Server you can declare DateTime and Date Fields.

When using SDAC you can set a Parameter like this way for a date-Field:

Code: Select all

But when you select values from a MS DB with:

Code: Select all

you only have "AsDateTime", which results in a cast error, when selecting a Date-Field.
In Delphi you also have "TDate". So it would be nice to have a "AsDate" Funktion also when you are using FieldByName. Is there any way to achieve this?

The cause of the specified error is not SDAC, but the behavior specificity of the standard TField class. To avoid it, please refer to the following article in Embarcadero documentation: ... AsDateTime
