The use process of the JDBC API: (1) Registering and loading the JDBC driver;
Two ways:
Class.forName (String drivername);
Drivermanager.registerdriver (Driver Driver)
(2) establishing a connection with the SQL database;
DriverManager's Getconnection () method:
Connection getconnection (string url): The URL represents the database address string;
Connection getconnection (String url,string user,string pwd)
Connection getconnection (String url,properties info)
(3) sending a SQL query;
Connection's Createstatement () method:
Statement createstatement ();
Statement can execute SQL statements and get the results of SQL queries.
(4) Obtain the result set.
Statement Execute SQL statement method:
ResultSet executequery (String sql): Executing a SELECT statement
int executeupdate (String sql): Executes an UPDATE statement, such as Insert,delete,update.

The

(5) Retrieves the results of the query.
    resultset methods;
    Boolean next (): False when no rows are returned;
    String getString (String columnName): Returns the value corresponding to the column name.
