"Persist Security Info=False;database=MyDB;server=MySqlServer;user id=myUser;Password=myPass" The ConnectionString property can be set only when the connection is closed. You can rate examples to help us improve the quality of examples. The example assumes that you are connecting to the default SQL Server instance on the server. The MySQL / MariaDB dialects will normally transfer any keyword specified as mysql_keyword_name to be rendered as KEYWORD_NAME in the CREATE TABLE statement. If your own code creates the database, or if you detach the database and run the project again after the .mdf file is already created, the database name is the full path to the .mdf file, including the file name. ; Connection details Connection URL. column) you specify (your_field).
