B4J Question mysql : difference between InitializeAsync and Initialize2

[giannimaione]

hello;

SQL.InitializeAsync("MySQL", "com.mysql.jdbc.Driver", $"jdbc:mysql://${DBLocation}/register_Northwind_MySQL?useSSL=false"$, DBUsername, DBPassword)
'or
SQL.Initialize2("com.mysql.jdbc.Driver", "jdbc:mysql://" & ip & "/database","username","password")

can someone explain difference ?
what is best solution?

If this is a UI app then you should use InitializeAsync with Wait For SQL_Ready (Success As Booolean)

Otherwise the app will freeze until the connection is ready. This can take a long time.
