Create firebird database programmatically with Qt

guidupas

Hello SGaist!

Yes, I have the credentials but I dont figure out how to do that once QSqlDriver does not have it statement type.

How could I do that?

SGaist

Can you post the statement that you want to execute ?

guidupas

I must execute a CREATE DATABASE because I need to create a database from the Qt code, but QSqlDriver does not have a create statement.

@
QString queryString;
queryString += "CREATE DATABASE";
queryString += " '" + path + "'";
queryString += " USER 'sysdba'";
queryString += " PASSWORD 'masterkey'";
queryString += " DEFAULT CHARACTER SET UNICODE_FSS";
@

SGaist

Looks like there's a \ missing after sysdba

What error are you getting ?

guidupas

Yes SGaist, but the error don not appear in this code. Is is just what I need to create. The error appears when I try to run the code below:

@
bool DB::conectarServidorFirebird(QSqlDatabase db)
{
bool retorno = true;

db.setHostName("localhost");
db.setPassword("gui080381");
db.setUserName("sysdba");
//db.setPort(3050);

if(db.open())
{
    retorno = true;
}
else
{
    qDebug() << db.lastError();

    retorno = false;
}

return retorno;

}
@

It returns me the error:
QSqlError("-901", "Error opening database", "Can't access lock files' directory /tmp/firebird")

SGaist

Do you have the rights to access /tmp/firebird ?

guidupas

No. I dont think so. But my problem is that I intend to use this database embedded and the user of my software will not have a Firebird group to be inserted in.

There is some configuration to be made to change permissions?

SGaist

What's your exact target setup ?

guidupas

I need to create a database using Qt programming with any user that uses the software in any folder it wishes.

Is it possible?

SGaist

So you want standard user to be able to do privileged action ?

guidupas

I need to be able to create a database from Qt programming. I can access databases but I cant create it directly from the code using firebird.

It returns me this error:
QSqlError("-902", "Error opening database", "cannot attach to password database")

and sometimes this one:
QSqlError(”-901”, “Error opening database”, “Can’t access lock files’ directory /tmp/firebird”)

I am using this code:
@
bool DB::conectarServidorFirebird(QSqlDatabase db)
{
bool retorno = true;

db.setHostName("localhost");
db.setPassword("gui080381");
db.setUserName("sysdba");
//db.setPort(3050);

if(db.open())
{
    retorno = true;
}
else
{
    qDebug() << db.lastError();

    retorno = false;
}

return retorno;

}

Looks more like a firebird setup problem
