Hi,
I have these 2 problem? Is there a way in Oracle to read UNCOMMITED
data. i.e. in Oracle the normal behaviour is that a user's updates to a
table are visible to other users ONLY when the user commits. But in
Informix there is this thing called ISOLATION LEVELS. For example by
setting the ISOLATION LEVEL to DIRTY READ, a user will...

I have a question about oracle commit and transactions. Following scenario:
Process A performs a single sql-INSERT into a table and commits the
transaction. Then he informs process B (ipc) to read the new date. So
process B starts "select ..." but does not get the previously inserted
row. The timespan between commit and select is very short....

I have an object that has a fairly complex construction sequence, so I have
written a dedicated "factory" class that invokes the constructor of my object
class (which does nothing but instantiate the object and set default
blank/null values), and then does all the Db access and number crunching to
populate the new object. The factory returns...

I have been playing around with a subclass of dict wrt a recipe for
setting dict items using attribute syntax.
The dict class has some read only attributes that generate an
exception if I try to assign a value to them.
I wanted to trap for this exception in a subclass using super but it
doesn't happen.
I have read Guido's tutorial on new...

Hi,
I have a read only access file with a linked table that connects to a
sybase database. So I can still add data to the table even though its
read only since the table is really in sybase. However, I want to
import data from an excel file (either via a macro in excel or access)
but I always get an "Error 3051" because the access file is...

Directory.CreateDirectory(myDir);
DirectoryInfo lDir = new DirectoryInfo(myDir);
lDir.Attributes = FileAttributes.Normal;
When this code runs, my directory is created fine, but my directory is
always read only. At first I thought it was something with using
DirectoryInfo. However, I also ran the...

Hi,
I had the following doubts about the "For Read Only" clause.
1. How does a "for Read only" clause improve the performance?
2. How does a "for Read only" clause compare with "With UR" clause in
performance? Which is faster?
Can someone clarify on that?

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. ...
