Hi!

Hi !
I get the error below sometimes when retrieving a big amount of data using Datadapter.Fill(dataset,"table"). But when I send the command Fill again, there is no error. Is it a fault of IBM.Data.DB2.iSeries; Version: v1.0.3705 (is there an newer one for OS/400 Version ist V5R3 ?) or is it a hardware faoult (memory of as400 or pc) ?

Hi,
If I have a very big view in database, it covers 15 tables, each table has
1000 columns.
When I issue select * from view, the database will give error -- too many

Can I use a DataAdapter fill DataTable couple times? For example, I only
read 5000 columns from the view each time and I read 3 times. It has an id

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:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
