Hi All,
Currently testing Hunt database, and facing an issue as

The hunt database class has a prepare method which expects a
SqlConnection as first argument and a string as second
argument. You are passing only a string, therefore the first
error.
Ad you name your database instance also connection (conn) and
your Connections class database (mdb) it makes the source code
quite hard to understand :)
Kind regards

Hi Andre,
We have also tried to change the connection (con) as dbconnect
(con) as below, as per the example provided in the link
https://code.dlang.org/packages/hunt-database, we dont see the
prepare method needs SqlConnection as first argument and a string
as second where as we can see the need from the source code, so
is the example provide in the link is wrong? if yes can you
please provide an example nor point me to the correct
documentation link
"Statement stmt = db.prepare("SELECT * FROM user where username =
:username and age = :age LIMIT 10");"
