How do i select all entries in a table

[JOJO]

Hello!

I have no idea how to use the search function. I tryed 5 or 6 times, but it dont let me search.

So i ask my question in the forum.

How do i select all entries in a table like: select * from comment?

I tryed it by using the fetch_all function, but i get always a [QxOrm] qx::QxSqlDatabase : 'parameters are not valid' error.

I tried it by:

Code: Select all

std::list<comment> comment_ = std::list<comment>()
qx::dao::fetch_all<comment>(comment_ );


and by:

Code: Select all

comment comment_ = comment();
qx::dao::fetch_all<comment>(comment_ );


Can anyone tell me what i am doing wrong here?

Hello,

[QxOrm] qx::QxSqlDatabase : 'parameters are not valid'

This error means that you didn't define the connection settings to your database.
You should read the QxOrm manual here : http://www.qxorm.com/qxorm_en/manual.html#manual_310

Then, to get all entries, you can write :

Code: Select all

std::list<comment> comment_;
qx::dao::fetch_all(comment_);
