Is that an error from the compiler or from the code completion in your IDE? – Alan Birtles Sep 23 '22 at 08:39

@AlanBirtles the error is from code completion on visual studio IDE – Robert Kims Sep 23 '22 at 08:42

Does the compiler work? If so just ignore intellisense, sometimes it gets confused (unless you're using vscode? The intellisense configuration is separate from the compiler configuration) – Alan Birtles Sep 23 '22 at 08:59

The compiler does not work since functions of pqxx are throwing errors because namespace is not recognized – Robert Kims Sep 23 '22 at 09:07

Have you configured your projects to use the library? – Alan Birtles Sep 23 '22 at 09:09

Yes I have added include folder to 'C/C++\General\Additional Include Directories' but still not change – Robert Kims Sep 23 '22 at 09:17

Yes, the project is configured well – Robert Kims Sep 23 '22 at 09:59

Are you sure you've changed the active configuration? – Alan Birtles Sep 23 '22 at 11:17

But are you sure you've alerted the same configuration that you're building? It's radio enough to accidentally set the wrong one in vs – Alan Birtles Sep 23 '22 at 13:39

Does [this](https://stackoverflow.com/questions/59860307/namespace-pqxx-not-recognized-issues-adding-libpqxx-to-c-visual-studio-postg) can help you. It looks like a similar problem. – Jingmiao Xu-MSFT Sep 26 '22 at 05:54
