Question

I have created a SQLite database in C# and i used that query to create a table.

string q = "create table mains ( id int IDENTITY, desc varchar(20), PRIMARY KEY(id) )"; 
ExecuteQuery(q);

And i tried adding a record like that :

string txtSQLQuery = "insert into  mains (desc) values ('" + textBox1.Text + "')";
ExecuteQuery(txtSQLQuery);

I just added a desc and not ID , i guess it should auto increment the id field but it does not.
Instead it adds the desc and the the ID field is empty every time i add a new record

EDIT :
i tried using :

id int PRIMARY KEY AUTOINCREMENT

But got Error :

SQLite.SQLiteException: near "AUTOINCREMENT":

EDIT 2 :
I get that when i load the records :

There are no Numbers in the ID field at all.

Answer 1

try

create table mains (id INTEGER  PRIMARY KEY, desc varchar(20))

A column declared INTEGER PRIMARY KEY will autoincrement.

Edit

As an alternative try executing

string txtSQLQuery = "insert into mains (id, desc) values (NULL, '" + textBox1.Text + "')";
