DB2 - Beyond case statements

2 New Member
All - below is part of a construct I am using. I have some very complex data and processing to perfrom and I need a way to get beyond case limitations.
Anyone know of other more robust constructs available in SQL - DB2.
The book says only 3 levels of nested case statements are allowed - that is true.
Any assistance would be appreciated.

select
field1
, field2

,case

when < condition >
then statement
else
case
when
then
when
then
when
then
( up to 12 times
end

I do this 9 times, it will work.

When I add a tenth structured statement, it fails


end as "Field Name"


from
mulitple tables / joins, etc.

Hi all, I skimmed through the docs for Python, and I did not find anything like a case or switch statement. I assume there is one and that I just missed it. Can someone please point me to the appropriate document, or post an example? I don't relish the idea especially long if-else statements. Joe

hello. i've been beating my head against a wall over this for too long. setting the variables 'z' or 'y' to differing numbers, the following 'if/else' code snippet works fine; however, the 'case' code snippet does not. (the code's function is illustrative.) ////////////////////////////////////////// //////// working 'if/else' switch //////// //////////////////////////////////////////

All, I rely on nested IF statements with multiple conditions heavily, and someone suggested recently writing the statements (and especially reading them months later) would be much easier if I used Case statements instead. I've read several different examples of Case statements, but can't quite figure out the syntax, or if they can be used when you need to test for a pair of conditions, as I am doing below.

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: g++-12 -std=c++20 -Wnarrowing bit_field.cpp Here is the code in...

In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
