How do I auto create student id number in mysql? -

-

i'm new mysql. created table student.

create table student(     studentid int(10) not null,     firstname varchar(100) not null,     lastname varchar(100) not null,     birthday varchar(12) not null,     gender varchar(7),     course_name varchar(150) not null,     primary key(studentid ) );

i thought nice studentid auto create system. , don't know how this. may simple question guys. please me this.

thanks.

the auto_increment attribute can used generate unique identity new rows:

ex - 

create table animals (      id int not null auto_increment,      name char(30) not null,      primary key (id) );

when inserting data table don't have input data id. 

 insert animals (name) values         ('dog'),('cat'),('penguin'),         ('lax'),('whale'),('ostrich');

which returns - 

+----+---------+ | id | name    | +----+---------+ |  1 | dog     | |  2 | cat     | |  3 | penguin | |  4 | lax     | |  5 | whale   | |  6 | ostrich | +----+---------+

answer question - 

create table student(         studentid int(10) not null auto_increment,         firstname varchar(100) not null,         lastname varchar(100) not null,         birthday varchar(12) not null,         gender varchar(7),         course_name varchar(150) not null,         primary key(studentid )     );

when getting data populate data grid, have pulled data, made list , mapped model, this: public list<person> getpeople() { var data = _db.person.tolist(); list<person> people = new list<person>(); foreach (var item in data) { person person = new person() { personid = item.personid, firstname = item.firstname, lastname = item.lastname }; people.add(person); } return people; } this works fine, in interest of writing less code discovered .select method , (what think is) anonymous type. have: public list<person> getpeople() { return _db.person.select(d => new person { personid = item.personid, firstname = item.firstname, lastname = item.lastname }).tolist(); } though not easy read, works fine too. there preference either way? ...

Listeners to visualise results of load test in JMeter -

i want run load test in non-gui mode , save results in .csv file. (i have not modified .properties files, standard information saved) i plan load file , visualise results jmeter’s listeners. which listeners suited purpose? should avoid @ cost, might cause me misinterpret information? (e.g. in view results tree response data empty have - - not saved this. however, there has in fact been response. if saw listener might think there hasn’t been one. since want avoid this, listeners have gain information needed .csv file.) i’d know both jmeter listeners plugins. if running test in non-ui mode ideally should disable listeners in script. use '-l' option store test results .jtl extension. can later open jtl file jmeter. aggregate report or summary report should summarize test results , response time , throughput. if want plot graphs see trends on test duration can use http://jmeter-plugins.org/#/ standard , lib set. i suggest following listeners: response ...
