Hi,

thanks for pointing that out. It appears that Sqlite3 is not compatible here with the concept of 'schema upgrade'. Not quite sure how to really resolve this issue.

However it works when you create tables. Here is my schema upgrading code:

	All_Tables(sch);
	if (sch.ScriptChanged(SqlSchema::SCHEMA))
		Sqlite3PerformScript(sch.Schema());
	if (sch.ScriptChanged(SqlSchema::UPGRADE))
		Sqlite3PerformScript(sch.Upgrade());
	if (sch.ScriptChanged(SqlSchema::ATTRIBUTES))
		Sqlite3PerformScript(sch.Attributes());
	if (sch.ScriptChanged(SqlSchema::CONFIG)) {
		Sqlite3PerformScript(sch.ConfigDrop());
		Sqlite3PerformScript(sch.Config());
	}

Unless you add a primary key on two columns in an existing table it works ok.
