Problem IC63931
|
Status: Geschlossen |
FUNCTIONS DAYNAME & MONTHNAME MAY RETURN INCORRECT RESULTS IF IN PUT IS NOT TIMESTAMP AND SYSTEM IS SET_UP WITH NON-EN_US LOCALE |
| Produkt: |
DB2 FOR LUW / DB2FORLUW / 970 - DB2 |
| Problembeschreibung: |
The scalar functions DAYNAME and MONTHNAME may be resolved as
SYSFUN version instead of SYSIBM version when the expression
argument is not a timestamp. The SYSFUN version may return
different results because the SYSFUN version does not
depend on the CURRENT LOCALE LC_TIME special register.
For example, if the CURRENT LOCALE LC_TIME is a fr_FR locale
then the correct output for
MONTHNAME('2007-03-09-14.07.38.123456') would be 'mars'. But
since the expression is not a timestamp, the en_US value of
'March' is returned in error.
If the locale is en_US, then this problem will not occur and the
correct results will be returned.
The problem only has impact for locales other than en_US.
However, please, note that SYSFUN version will not perform as
well as the SYSIBM version.
This APAR will ensure that SYSIBM version is used and will
improve performance for en_US locales as well. |

| Local-Fix: |
Two possible local fixes are:
1) Qualify the function with SYSIBM, for example
SYSIBM.MONTHNAME('2007-03-09-14.07.38.123456') will return
'mars' in a fr_FR locale as expected
2) Specify the expression with type as timestamp, for example
MONTHNAME(timestamp '2007-03-09-14.07.38.123456') will return
'mars' in a fr_FR locale as expected |
