SNOW-1504369: Time value regression after 3.13.31
Closed this issue · 3 comments
Please answer these questions before submitting your issue.
In order to accurately debug the issue this information is required. Thanks!
-
What version of JDBC driver are you using?
3.13.30 vs 3.13.34 [31] -
What operating system and processor architecture are you using?
Win11/Talend studio -
What version of Java are you using?
11/17 -
What did you do?
If possible, provide a recipe for reproducing the error.
A complete runnable program is good.
Create a table with TIME column
Insert value 00:00:44 and do the plain select via jdbc driver (ResultSet::getTime)
with 3.13.30 it's 44580 for me and starting from 3.13.31 it's -10755420
- What did you expect to see?
value is the same
What should have happened and what happened instead?
value has changed
I did some research and it seems it's starting from #1383
Before BigIntToTimeConverter returned a UTC time value with timezone, and after it's already the timezoned value for java.sql.Time
The deactivation of useSessionTimezone
flag might help but would affect other columns' values.
Hi @dmytro-sylaiev,
Thank you for opening this issue. I checked out the main branch and tried to reproduce what you're seeing with the following code:
connection = getConnection();
statement = connection.createStatement();
statement.executeQuery("Alter session set JDBC_USE_SESSION_TIMEZONE=false");
statement.executeQuery("CREATE OR REPLACE TABLE T_TIME(time_col TIME)");
statement.executeQuery("INSERT INTO T_TIME VALUES('00:00:44')");
ResultSet resultSet = statement.executeQuery("Select time_col from T_TIME");
Time t = Time.valueOf("00:00:44");
resultSet.next();
Time result_t = resultSet.getTime(1);
assertEquals(t, result_t);
That test passes, so I'm not observing the same issue you are.
What is the TIMEZONE
parameter set to in Snowflake at your end?
show parameters like 'timezone';
Have you tested this with JDBC driver version 3.16.1?
Hey @dmytro-sylaiev,
