Why comma is expected for auto_increment?

+0
−2
query = "CREATE TABLE "+TABLE+" ("+COLUMN1+" INTEGER PRIMARY KEY NOT NULL AUTO_INCREMENT, "+COLUMN2+" VARCHAR(255), " +
         COLUMN3+" VARCHAR(255), "+COLUMN4+" TEXT, "+ COLUMN5+" VARCHAR(255), "+COLUMN6+" VARCHAR(255), "+COLUMN7+" TEXT)";

error

')',, ON or comma expected, got 'AUTO_INCREMENT'

I am very new to SQL. Earlier I was using Xampp.

Why comma expected for AUTO_INCREMENT? If I write the command something just like this :

"+COLUMN1+" INTEGER PRIMARY KEY NOT NULL ,AUTO_INCREMENT,

then I don't get the error/warning. But I think if I use comma then SQL may think AUTO_INCREMENT isn't for COLUMN1's. Cause it might be separated by comma.

I was trying to follow this answer:

 "CUST_ID" INT not null primary key
        GENERATED ALWAYS AS IDENTITY
        (START WITH 1, INCREMENT BY 1)

But I got same error on GENERATED at first then AS. My attempt is available in the answer.

I have tried IDENTITY also.

Personid int IDENTITY(1,1) PRIMARY KEY,

same error for IDENTITY

Read the documentation for SQLite CREATE TABLE clauses, not questions about Netbeans JavaDB.

In particular, if you expand column-def and column-constraint you'll see the correct syntax for what you're trying to do.

However, note also that it's not recommended unless "strictly needed".
