ARROW-7301: [Java] Sql type DATE should correspond to DateDayVector
According to SQL convertion, sql type DATE should correspond to a format of YYYY-MM-DD, without the components for hour/minute/second/millis Therefore, JDBC type DATE should correspond to DateDayVector, with a type width of 4, instead of 8. Closes #5944 from liyafan82/fly_1203_date and squashes the following commits: a6de377 <liyafan82> Remove division in time conversion be73192 <liyafan82> Resolve comments eea8b79 <liyafan82> Sql type DATE should correspond to DateDayVector Authored-by: liyafan82 <fan_li_ya@foxmail.com> Signed-off-by: Micah Kornfield <emkornfield@gmail.com>
