AUTO INCREMENT statement in SQL

[Aviram 0]

Hi .
I'm having trouble with the AUTO INCREMENT statement in SQL.
I've built the table :

CREATE TABLE tenants(
    apartment_number_first_floor INT AUTO_INCREMENT,
    family_name VARCHAR (12) DEFAULT NULL,
    sur_name VARCHAR (8) DEFAULT NULL,
    telephone_number INT(3) NOT NULL,
     PRIMARY KEY (apartment_number_first_floor)
    );

when inserting a row:
        INSERT INTO tenants VALUES(' ',' ');
The IDE doesn't accept the column count:
        ER_WRONG_VALUE_COUNT_ON_ROW: Column count doesn't match value count at row 1

So i tried filling the rows just to check if the IDE will run  the statement
       INSERT INTO tenants VALUES(103,'שקלובין','מרתה',203);
 but the IDE refuses to increment 

 

Any ideas?
Thanks

You need to pass null for that column if you want it to auto-increment.  Or, better yet, list the columns you are inserting and leave out the auto-increment column completely.

Hello,  @Aviram

Please try this query, To AUTO INCREMENT statement in SQL:

CREATE TABLE tenants(
    apartment_number_first_floor INT IDENTITY(1,1) PRIMARY KEY,
    family_name VARCHAR (12) DEFAULT NULL,
    sur_name VARCHAR (8) DEFAULT NULL,
    telephone_number INT(3) NOT NULL,
    );

I hope above query will be useful for you.

Thank you.
