MDEV-36216 TO_CHAR FM format not recognized in SQL_MODE=Oracle
Adding support for the "FM" format in function TO_CHAR(date_time, fmt).
"FM" in the format string disables padding of all components following it.
So now TO_CHAR() works as follows:
- By default string format components DAY (weekday name) and
MONTH (month name) are right-padded with spaces to the maximum
possible DAY and MONTH name lengths respectively,
according to the current locale specified in @@lc_time_names.
So for example, with lc_time_names='en_US' all month names are
right-padded with spaces up to 9 characters ('September' is the longest).
SET lc_time_names='en_US';
SELECT TO_CHAR('0001-02-03', 'MONTH'); -> 'February ' (padded to 9 chars)
NEW: When typed after FM, DAY and MONTH names are not right-padded
with trailing spaces any more:
SET lc_time_names='en_US';
SELECT TO_CHAR('0001-02-03', 'FMMONTH'); -> 'February' (not padded)
- By default numeric components YYYY, YYY, YY, Y, DD, H12, H24, MI, SS
are left-padded with leading digits '0' up to the maximum possible
number of digits in the component (e.g. 4 for YYYY):
SELECT TO_CHAR('0001-02-03', 'YYYY'); -> '0001' (padded to 4 chars)
NEW: When typed after FM, these numeric components are not left-padded
with leading zeros any more:
SELECT TO_CHAR('0001-02-03', 'FMYYYY'); -> '1' (not padded)
- If FM is specified multiple times in a format string,
every FM negates the previous padding state:
* an odd FM disables padding
* an even FM enables padding
Implementation details:
- Adding a helper class Date_time_format_oracle.
- Adding a helper method Date_time_format_oracle::append_lex_cstring()
- Moving the function append_val() to Date_time_format_oracle as a method.
- Moving the function make_date_time_oracle() to Date_time_format_oracle
as a method format().
- Adding helper methods month_name() and day_name() in class MY_LOCALE,
to return the corresponding components as LEX_CSTRINGs.
