Quite suddenly, it seems, our DB does not recognize these functions:
UPPER
LOWER
LTRIM
LEAST
LOG
The error message is:
SQL0440N No authorized routine named "LOG" of type "FUNCTION" having
compatible arguments was found. SQLSTATE=42884
There might be others, we haven't tested them all. These functions
continue to work:
MIN
MAX
SUBSTR
Running 8.2.0 on Linux.
6  4911 
I should add that we had a WebSphere application connected to this
database, and it continued to perform normally, until we bounced it,
and now it fails (SQL0440N) whenver trying to invoke, for example,
LOWER.
Check that the LOG function does exist in the catalogs:
C:\>db2 select substr(funcname , 1, 5) as funcname, substr(funcsche ma, 1, 8) as funcschema from syscat.function s where funcname = 'LOG'
FUNCNAME FUNCSCHEMA
-------- ----------
LOG SYSFUN
1 record(s) selected.
And if it does, make sure that schema is in your CURRENT FUNCTION PATH special register:
C:\>db2 values current function path
1
--------------------------------------------------------------------------------
"SYSIBM","SYSFU N","SYSPROC","L MENARD"
1 record(s) selected.
Note that the WebSphere app could conceivably be modifying its own CURRENT FUNCTION PATH, so that what you get from a CLP connection won't necessarily reflect what the app would see.

Also note that really bad things can happen if teh systemclock gets
reset/turned backwards.
Check CURRENT TIMESTAMP and make sure its prior to when the database was
created (you can check the create time of a system object to compare)
Function resolution goes by TIME, PATH, privileges and signature.

Any recent changes in fixpak levels to DB2?
Larry Edelstein
Timestamp looks normal, I'm not aware of any resets.
We recently upgraded from FixPak5 to FixPak7, but that was before we
created the database and installed the application.

Hi all...
Either I'm doing really something really stupid - or maybe there is
some bug somewhere (optimizing?). In a function I have:
int x1, y1, x2, y2;
float dR, dX, dY;
dR = (state.cam1x - x1) - (state.cam2x - x2);
dX = 0.5 * ((state.cam1x - x1) + (state.cam2x - x2));

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows.
