I just tested the getConnection call. Noel is right: the second call just
needs 14 mSec (user sa, empty password).
As I am new to H2 and Raspberry there are many questions. Not all are
covered by the manual.
Is it ok to use the same connection by serveral threads if the access is
synchronized as follows:
int getCount()
{
synchronized(this) {
Statement stmt=connection.createStatement ( ... );
ResultSet rs=stmt.executeQuery("count (*) as count form messwerte ");
return rs.getInt("count");
}
}
