Subject [jira] [Created] (CALCITE-1371) PreparedStatement does not process Date type correctly
Date Wed, 07 Sep 2016 03:15:20 GMT

------------------------------------------

             Summary: PreparedStatement does not process Date type correctly 
                 Key: CALCITE-1371
                 URL: https://issues.apache.org/jira/browse/CALCITE-1371
             Project: Calcite
          Issue Type: Bug
          Components: core
    Affects Versions: 1.8.0
            Reporter: Billy(Yiming) Liu
            Assignee: Julian Hyde
            Priority: Minor


I have problem when passing date parameter in PreparedStatement. Following is the sample code:
TimeZone tzUtc = TimeZone.getTimeZone("UTC");
Calendar cUtc = Calendar.getInstance(tzUtc);
cUtc.set(2013, 10, 5, 0, 0, 0);
java.sql.Date passSqlDate = new java.sql.Date(cUtc.getTimeInMillis());
statement.setDate(1, passSqlDate, cUtc);
I try to pass Date'2013/11/5' to the database, but from the debug info I found the 
database received '2013/10/4' (GMT -8 Timezone) always. It ignored the Calendar I passed in.

There are some Calcite code a little strange, I have marked by color:
Why setTimestamp and setTime have effective parameter 'calendar', but setDate ignore the
parameter. Is that the root cause?
AvaticaSite.java
Line 189-199
  public void setTimestamp(Timestamp x, Calendar calendar) {
    slots[index] = wrap(ColumnMetaData.Rep.JAVA_SQL_TIMESTAMP, x, calendar);
  }

  public void setTime(Time x, Calendar calendar) {
    slots[index] = wrap(ColumnMetaData.Rep.JAVA_SQL_TIME, x, calendar);
  }

  public void setDate(Date x, Calendar cal) {
    slots[index] = wrap(ColumnMetaData.Rep.JAVA_SQL_DATE, x, calendar);
  }
