title: Auto increment in Oracle SQL
body: <p>I am trying create a table with auto increment in Oracle SQL. I have the following SQL code:</p>
  
  <pre><code>DROP TABLE "Account" CASCADE CONSTRAINTS;
  CREATE TABLE "Account" (
    "Id" NUMBER(5) NOT NULL,
    "Name" VARCHAR2(32) NOT NULL,
    "User" VARCHAR2(16) NOT NULL,
    "Email" VARCHAR2(32) NOT NULL,
    "Password" VARCHAR2(16) NOT NULL,
    "Level" VARCHAR2(16) NOT NULL,
    CONSTRAINT "Account_pk" PRIMARY KEY ("Id")
  );
  
  DROP SEQUENCE "Account_seq";
  CREATE SEQUENCE "Account_seq" START WITH 1
  INCREMENT BY 1
  MINVALUE 1
  MAXVALUE 10000;
  
  INSERT INTO "Account" VALUES (Account_seq.NEXTVAL, 'xxx', 'xxx', 'xxx', 'xxx', 'user');
  INSERT INTO "Account" VALUES (Account_seq.NEXTVAL, 'xxx', 'xxx', 'xxx', 'xxx', 'user');
  </code></pre>
  
  <p>Oracle SQL Developer says that Account_seq is created, but still it gives me an error: "sequence does not exist"...</p>
