Hello Attila Jeges, Impala Public Jenkins,
I'd like you to reexamine a change. Please visit
http://gerrit.cloudera.org:8080/14291
to look at the new patch set (#14).
Change subject: IMPALA-8704: ISO:SQL:2016 datetime patterns - Milestone 2
......................................................................
IMPALA-8704: ISO:SQL:2016 datetime patterns - Milestone 2
This patch adds additional datetime format tokens on top of what was
introduced with Milestone 1 (IMPALA-8703).
The tokens introduced:
- Free text token: Surrounded by double quotes, a free text section
can be given in the format where the same text is expected in the
input without the surrounding double quotes.
- FX modifier: This modifier has to be given at the beginning of the
format and is valid for the whole format.
In a string to datetime conversion this forces strict separator
matching and expects all the tokens in the input to have the same
length as their maximum length. E.g. A month has to be of length 2
prefixed by zero if needed.
This is the default in a datetime to string conversion.
- FM modifier: This modifier affects only the following token and
overrides the FX modifier.
In a string to datetime conversion when using this modifier the
length of the token in the input can be shorter than the max length
of that token type if followed by a separator. E.g. 1-digit month,
less than 4-digit year, etc. This is the default behaviour in a
string to datetime conversion.
In a datetime to string conversion tokens with this modifier aren't
padded to the maximum length. Example output: "2010-1-9".
