how to get full QueryInterfaceRequest sql string in grdb including all arguments (GRDB.StatementArguments) in the string

Question

I need to get full sql query of query interface in order to save them in user defaults but i couldn't find this functionality

update: in order to achieve full query string:

1. including arguments that were trimmed by sqlite for injection you can not replace those arguments with question mark manualy.

2. you can not achieve real value of those arguments because they are private

Answer 1

There is a trace function in the latest GRDB:

// Prints all SQL statements
var config = Configuration()
config.prepareDatabase { db in
    db.trace { print($0) }
}
