Hi, Corwinjoy, I met this mysterious problem about "number" the parameter. (I know in <3.6.5 there is a problem with it, so I used 3.6.6 version) I created a...
I just find that I must mistakenly typed a wrong name for one field. When I changed everything to use the same string (DB table, C++ struct table, field in...
Sorry the error message was so bad on this. What's happening here is it is asks the database if it needs to send any data to fill in the parameters. If you...
Hi, Corwinjoy, I met this problem when I want to query on a joint table. Maybe it is a silly question but I could not figure out a way to do it and cannot find...
James, The problem here is that when you use a select_iterator with DynamicDBView, the view tries to be smart and build the sql query for you. (See the...
Vasco, I looked over your changes and it turns out that in the current code we take any empty strings or blobs and write them as null values to the database....
Corwin, Thank you for your feedback. The fact that you can not reproduce the problem with Oracle 7.3 leads me to believe that this is a problem specific to the...
Hi Corwin, I'm still running v3.3.2 of the DTL, and have a crash problem that I'm not sure how to fix properly. If I have my application connect to a database,...
Dave, I am not sure what is causing this in your case, but we have seen a similar effect occasionally with DLLs. Perhaps this tip from the FAQ will help ... ...
Hi Corwin, Actually, I did wrap the DTL in my own DLL! And it turns out that the call to GetDefaultEnvironment()->Release() was all I needed to do my ...
The error message you are getting indicate that the linker is failing to find the ODBC libraries. From your link line it looks like you forgot to link them...
To apply, save it in the DTL dir, go to the DTL dir and type: patch -p0 < nullable.patch Also included is a little test file. Details: I needed a native type...
Hi, I wanted to use a DefaultBCA that did NOT have a default constructor. This is not possible as the dtl::iterators' default constructors try to construct a...
Hi, This is a kind-of lessons-learned that will hopefully improve the documentation, or at least the understanding of the DTL... I had run into several...
Hi everyone, I am trying to install DTL on a linux platform. I get the following error when I try to build. It asks for a "sql.h". I looked into one of the...

I downloaded MyODBC (an odbc driver for MySQL). Will I be limited to just unixODBC driver? I would like to play with many different drivers and experiment with...
I will take a look at this over Thanksgiving since I've been quite busy. Some initial thoughts: -The nullable patch looks like a nice extension - BUT a. The...
There are two distinct pieces here. The first is the ODBC implementation which loads database drivers. Examples would include: -unixODBC, iODBC, Microsoft...
Nevermind guys, I had a typo in this line:cols["OuputStructName"] == rowbuf.m_szOutputStructName;" I spelt "OutputStructName" wrongly. I could just kick myself...
Hi, Assume that I have different DBMSs running on a server (MySQL, Oracle, and SQLServer), and that I had installed all their ODBC drivers. How can I configure...
Unfortunately Access (and other drivers) don't always give the best error messages which can waste a lot of time. The first thing I always do is that whenever...
