@ Mysql_connect ("localhost", "root", "1981427") // you must connect to the database server before selecting a database.
Or die ("database server connection failed ");
@ Mysql_select_db ("test") // select the database mydb
Or die ("The database does not exist or is unavailable ");
$ Query = @ mysql_query ("select * from tablename1") // execute an SQL statement
Or die ("SQL statement execution failed ");
?>

The code is as follows:

@ Mysql_connect ("localhost", "root", "1981427") // you must connect to the database server before selecting a database.
Or die ("database server connection failed ");
@ Mysql_select_db ("test") // select the database mydb
Or die ("The database does not exist or is unavailable ");
$ Query = @ mysql_query ("insert into tablename1 values ('4', 'Judy ', '123 ')")
Or die ("SQL statement execution failed ");
?>
