Adaptive Server supports the SQL datetime, smalldatetime, date, and time datatypes. date and time provide the following advantages:
Date values can be between Jan. 1, 0001 and Dec. 31, 9999, exactly matching the allowable values in java.sql.Date.
A direct mapping exists between java.sql.Date and the date datatype, as well as between java.sql.Time and the time datatype.
If you select from a table that contains a date or time column, and you have not enabled date/time support in jConnect (by setting the version), the server tries to convert the date or time to a datetime value before returning it. This can cause problems if the date to be returned is prior to 1/1/1753. In that case, a conversion error occurs, and the database informs you of the error.
SQL Anywhere supports a date and time datatype, but the date and time datatypes are not yet directly compatible with those in Adaptive Server version 12.5.1 and later. Using jConnect, you should continue to use the datetime and smalldatetime datatypes when communicating with SQL Anywhere.
The maximum value in a datetime column in SQL Anywhere is 1-1-7911 00:00:00.
Using jConnect, you receive conversion errors if you attempt to insert dates prior to 1/1/1753 into datetime columns or parameters.
Refer to the Adaptive Server manuals for more information on the date and time datatypes; of special note is the section on allowable implicit conversions.
If you use getObject with an Adaptive Server date, time, or datetime column, the value returned is, respectively, a java.sql.Date, java.sql.Time, or java.sql.Timestamp datatype.
