As id is the primary key  you cannot have different rows with the same value  Try to change your table so that the id is auto incremented   id int NOT NULL AUTO INCREMENT   and then set the primary key as follows   PRIMARY KEY  id    All together   CREATE TABLE card games      id int 11  NOT NULL AUTO INCREMENT     nafnleiks varchar 50      leiklysing varchar 3000       prentadi varchar 1500       notkunarheimildir varchar 1000      upplysingar varchar 1000      ymislegt varchar 500      PRIMARY KEY  id      Otherwise  you can indicate the id in every insertion  taking care to set a different value every time   insert into card games  id  nafnleiks  leiklysing  prentadi  notkunarheimildir  upplysingar  ymislegt   values 1   Svartip  tur    Leikl  singu vantar    Er prenta           rarinn Gu  mundsson  2010   Spilab  kin - Allir helstu spilaleikir og spil     Heimildir um notkun    rni Sigur  sson  1951   H  t    ir og skemmtanir fyrir hundra     rum    A  rar uppl  singar    ekkert h  r sem stendur

It amazing for me  for solving Field  id  doesn t have a default value  I have tried all the possible ways what are given here like    set sql mode    set   sql mode       etc   but unfortunately these didn t work for me  So after long investigation  I found that    Entity  Table name  vendor table   public class Customer        Id      Column name  cid       private int cid            Entity  Table name  vendor table   public class Vendor        Id     private int vid       Column     private String vname                here you can see that both tables are having same name  It is very funny mistake  was done by me        After correcting this my problem was gone off

I was getting error while ExecuteNonQuery   resolved with adding AutoIncrement to Primary Key of my table  In your case if you don t want to add primary key then we must need to assign value to primary key   ALTER TABLE  t1   CHANGE COLUMN  id   id  INT 11  NOT NULL AUTO INCREMENT

This is caused by MySQL having a strict mode set which won   t allow INSERT or UPDATE commands with empty fields where the schema doesn   t have a default value set   There are a couple of fixes for this   First    fix    is to assign a default value to your schema  This can be done with a simple ALTER command   ALTER TABLE  details  CHANGE COLUMN  delivery address id   delivery address id  INT 11  NOT NULL DEFAULT 0     However  this may need doing for many tables in your database schema which will become tedious very quickly  The second fix is to remove sql mode STRICT TRANS TABLES on the mysql server   If you are using a brew installed MySQL you should edit the my cnf file in the MySQL directory  Change the sql mode at the bottom    sql mode NO ENGINE SUBSTITUTION STRICT TRANS TABLES sql mode NO ENGINE SUBSTITUTION   Save the file and restart Mysql   Source  https   www euperia com development mysql-fix-field-doesnt-default-value 1509

There are 2 solutions mentioned below   Solution 1  MySQL is most likely in STRICT SQL mode  Try to execute SQL query SET GLOBAL sql mode    or edit your my cnf   my ini to make sure you aren t setting STRICT ALL TABLES and or STRICT TRANS TABLES   Solution 2  If Solution-1 is not working then try Solution-2 as given in below steps    Run MySQL Administrator tool as Administrator  Then go to Startup Variable  Then go to the Advance tab  find SQL Mode and remove the STRICT ALL TABLES and or STRICT TRANS TABLES and then Click on Apply Changes  Restart MySQL Server  Done    Note  I have tested these solutions in MySQL Server 5 7

The id should set as auto-increment   To modify an existing id column to auto-increment  just add this  ALTER TABLE card games MODIFY id int NOT NULL AUTO INCREMENT

Solution  Remove STRICT TRANS TABLES from sql mode    To check your default setting    mysql gt  set   sql mode     STRICT TRANS TABLES NO AUTO CREATE USER NO ENGINE SUBSTITUTION   Query OK  0 rows affected  0 00 sec   mysql gt  select   sql mode   ----------------------------------------------------------------      sql mode                                                        ----------------------------------------------------------------    STRICT TRANS TABLES NO AUTO CREATE USER NO ENGINE SUBSTITUTION    ----------------------------------------------------------------  1 row in set  0 00 sec    Run a sample query    mysql gt  INSERT INTO nb  id  VALUES 3   ERROR 1364  HY000   Field  field  doesn t have a default value   Remove your STRICT TRANS TABLES by resetting it to null     mysql gt  set   sql mode       Query OK  0 rows affected  0 00 sec    Now  run the same test query     mysql gt  INSERT INTO nb  id  VALUES 3   Query OK  1 row affected  1 warning  0 00 sec    Source  https   netbeans org bugzilla show bug cgi id 190731

For me the issue got fixed when I changed   lt id name  personID  column  person id  gt       lt generator class  native   gt   lt  id gt    to   lt id name  personID  column  person id  gt       lt generator class  increment   gt   lt  id gt    in my Person hbm xml   after that I re-encountered that same error for an another field mobno   I tried restarting my IDE  recreating the database with previous back issue got eventually fixed when I re-create my tables using  without ENGINE InnoDB DEFAULT CHARSET latin1  and removing underscores in the field name   CREATE TABLE  tbl customers       pid  bigint 20  NOT NULL     title  varchar 4  NOT NULL     dob  varchar 10  NOT NULL     address  varchar 100  NOT NULL     country  varchar 4  DEFAULT NULL     hometp  int 12  NOT NULL     worktp  int 12  NOT NULL     mobno  varchar 12  NOT NULL     btcfrom  varchar 8  NOT NULL     btcto  varchar 8  NOT NULL     mmname  varchar 20  NOT NULL     instead of  CREATE TABLE  tbl person       person id  bigint 20  NOT NULL     person nic  int 10  NOT NULL     first name  varchar 20  NOT NULL     sur name  varchar 20  NOT NULL     person email  varchar 20  NOT NULL     person password  varchar 512  NOT NULL     mobno  varchar 10  NOT NULL DEFAULT  1      role  varchar 10  NOT NULL     verified  int 1  DEFAULT NULL   ENGINE InnoDB DEFAULT CHARSET latin1    I probably think this due to using ENGINE InnoDB DEFAULT CHARSET latin1    because I once got the error org hibernate engine jdbc spi SqlExceptionHelper  - Unknown column  mob no  in  field list  even though it was my previous column name  which even do not exist in my current table  Even after backing up the database with modified column name  using InnoDB engine  I still got that same error with old field name  This probably due to caching in that Engine

make sure that you do not have defined setter for the for your primary key in model class   public class User   Id  GeneratedValues private int user Id  private String userName   public int getUser Id  return user Id     public String getUserName  return userName     public void setUserName  this userName userName

As a developer it is highly recommended to use STRICT mode because it will allow you to see issues errors warnings that may come about instead of just working around it by turning off strict mode  It s also better practice    Strict mode is a great tool to see messy  sloppy code

Since mysql 5 6  there is a new default that makes sure you are explicitly inserting every field that doesn t have a default value set in the table definition   to disable and test this  see this answer here  mysql error 1364 Field doesn  39 t have a default values  I would recommend you test without it  then reenable it and make sure all your tables have default values for fields you are not explicitly passing in every INSERT query   If a third party mysql viewer is giving this error  you are probably limited to the fix in that link

To detect run  select   sql mode -- It will give something like  -- STRICT TRANS TABLES NO AUTO CREATE USER NO ENGINE SUBSTITUTION  To fix  run  set global sql mode

I had an issue on AWS with mariadb - This is how I solved the STRICT TRANS TABLES issue  SSH into server and chanege to the ect directory    ec2-user   cd  etc   Make a back up of my cnf   ec2-user etc   sudo cp -a my cnf   strict bak    I use nano to edit but there are others    ec2-user etc   sudo nano my cnf   Add this line in the the my cnf file     This removes STRICT TRANS TABLES   sql mode      Then exit and save  OR if sql mode is there something like this   sql mode NO ENGINE SUBSTITUTION STRICT TRANS TABLES   Change to   sql mode      exit and save  then restart the database   ec2-user etc   sudo systemctl restart mariadb
