I don't know of a "standard" sql procedure, but most databases have their own way of doing this: Oracle- use date math(sysdate - hiredate) Access- use the dateDiff(sysdate, hiredate) function. if the answer returns 0 then the it is the same day. note: This will cause portablility problems between different databases. If you can live with that, check your database documentation ... |

Ordin, I've never considered the approach that you mentioned, but it's worth having as an option. One disadvantage of using it is that it is database dependent. If your system uses Data Access Objects, though, you have already nicely layered and encapsulated database-specific code; hence, your approach could work very well with Data Access Objects. Thanks, Craig |

Like java.util.Date, all three classes in the SQL package are thin wrappers around a numeric value representing a point in time. The Date and Time classes ignore the information regarding the time of day or the calendar date, respectively. The Timestamp class, however, not only includes the usual time and date information up to millisecond precision, but also allows storing additional ... |
