Mygeneration: Obtain the database name of all Oracle databases. Name of the data table life Column

Use the mygeneration Automatic Generation Code tool to obtain the Database Name and data table name of all Oracle databases. The procedure is as follows:
1. Set the database link string provider = oraoledb. oracle.1; Password = mypassword; persist Security info = true; user id = myid; Data Source = mydatasource in default settings of mygeration
2. Copy the following code to the form on the interface code tab.
