For example: Strings in expressions are case sensitive except when you're querying personal geodatabase feature classes and tables. Finally choose the Get Unique Value button and double click 1988. When a nonnull time is stored with the dates (for instance, January 12, 1999, 04:00:00), querying against the date only will not return the record because when you pass only a date to a date-time field, it will fill the time with zeros and retrieve only the records where the time is 12:00:00 a.m. Configure the Select Layer By Attribute pane as follows: Select the feature layer for the Input Rows field.
