Mysql inserts multiple data instances into the table at a time.
Let's first create a table named Authors:
CREATE TABLE Authors(AuthID SMALLINT NOT NULL PRIMARY KEY,AuthFN VARCHAR(20),AuthMN VARCHAR(20),AuthLN VARCHAR(20))ENGINE=INNODB;
Insert multiple data entries into the table at a time. The SQL insert Code is as follows:
INSERT INTO Authors VALUES (1006, 'H', 'S.', 'T'), (1007, 'J', 'C', 'O'), (1008, 'B', NULL, 'E'), (1009, 'R', 'M', 'R'), (
Pmap provides memory ing for processes. The pmap command is used to display the memory status of one or more processes. It reports the address space and memory status of the process. Pmap is actually a command on Sun OS. linux only supports its limited functions. However, it is helpful for viewing the complete process address space. We need the PID or the unique process ID of the running process to view the process memory status. We can get it through/proc or conventional commands such as top or
Let's start by creating a table authors:
CREATE TABLE Authors (
authid SMALLINT not NULL PRIMARY KEY,
authfn VARCHAR (),
authmn VARCHAR ()
AUTHLN VARCHAR
)
Engine=innodb;
Then insert more than one piece of data into the table, and the SQL Insert code is as follows:
INSERT into Authors VALUES (1006, ' H ', ' S. ', ' T '),
(1007, ' J ', ' C ', ' O '),
(1008, ' B ', NULL, ' E '),
(1009, ' R ') , ' M ', ' R '), (
