Class DateColumnDescriptor

java.lang.Object
  uk.co.weft.dbutil.ColumnDescriptor
      uk.co.weft.dbutil.DateColumnDescriptor

Direct Known Subclasses:

TimeStampColumnDescriptor

public class DateColumnDescriptor

extends ColumnDescriptor

A descriptor for an date column.

NoteOn SQL Server 2000, the language definred for the logins controls the way in which dates are formatted for that user and if the dates don't format as we expect DateColumnDescriptor will fail to interpret them correctly.

If the language is set to 'English' (as opposed to either 'US English' or 'British English') the date collation works.
