Thread: Found a problem with 8.2-508 JDBC 4

PostgreSQL: 8.2.4

JDK: 1.6.0_07

JDBC Driver: 8.2-508 JDBC4

I have found a problem with 8.2-508 JDBC 4.  I can recreate the problem every time.

Summary of problem:

When the below SQL is executed the result set returns the value of “null” for the field “calendar_name”.  When I use driver “8.2-506 JDBC 4” and “8.2-507 JDBC 4” it work correctly and I get a valid value.

SQL that returns a “null” in 508 but not in 506 and 507 for the field “calendar_name”:

SELECT to_char(event.start_timestamp, 'Mon FMDD, YYYY') AS start_date,

 to_char(event.end_timestamp, 'Mon FMDD, YYYY') AS end_date,

 to_char(event.start_timestamp, 'FMHH:MI am') AS start_time,

 to_char(event.end_timestamp, 'FMHH:MI am') AS end_time,

 to_char(event.news_letter_timestamp, 'YYYYMMDD') AS news_letter_date,

 to_char(event.news_letter_timestamp, 'FMHHMISS') AS news_letter_time,

 to_char(last_updated_timestamp, 'MM/DD/YYYY') AS last_updated_date,

 to_char(event.created_timestamp, 'MM/DD/YYYY') AS created_date,

 event.*,

 calendar.name as calendar_name

FROM calendar.event, calendar.calendar

WHERE event.id=? AND event.fk_calendar_id=calendar.id

When I rearrange the following SQL, driver 508 will return a non “null” value for calendar_name.  Both the above and below SQL work with 506 and 507:

SELECT to_char(event.start_timestamp, 'Mon FMDD, YYYY') AS start_date,

 to_char(event.end_timestamp, 'Mon FMDD, YYYY') AS end_date,

 to_char(event.start_timestamp, 'FMHH:MI am') AS start_time,

 to_char(event.end_timestamp, 'FMHH:MI am') AS end_time,

 to_char(event.news_letter_timestamp, 'YYYYMMDD') AS news_letter_date,

 to_char(event.news_letter_timestamp, 'FMHHMISS') AS news_letter_time,

 to_char(last_updated_timestamp, 'MM/DD/YYYY') AS last_updated_date,

 to_char(event.created_timestamp, 'MM/DD/YYYY') AS created_date,

 calendar.name as calendar_name,

 event.*

FROM calendar.event, calendar.calendar

WHERE event.id=? AND event.fk_calendar_id=calendar.id
