SQLite in QT

[sophister]

I use this to create a table whick is a variable "tableName", why the following codes doesn't woek:

QSqlQuery build;
build.exec( QString("create table %1 ("
            "id INTEGER PRIMARY KEY AUTOINCREMENT,"
            "name VARCHAR(90)"
            "author VARCHAR(50)"
            "copy INTEGER"
            "press VARCHAR(120))").arg( name) )

QSqlQuery build;
build.exec( QString("create table %1 ("
            "id INTEGER PRIMARY KEY AUTOINCREMENT,"
            "name VARCHAR(90)"
            "author VARCHAR(50)"
            "copy INTEGER"
            "press VARCHAR(120))").arg( name) )

To copy to clipboard, switch view to plain text mode 

and before these codes, I have open the database.
Thanks in advance.
