PostgreSQL ENUM types throwing exception on insert using the generated DAO

[Jonathan]

Hi,

I have a postgres table containing an ENUM type as follows:

CREATE TYPE notification_type AS ENUM ('TYPE_A', 'TYPE_B', 'TYPE_C');

CREATE TABLE users
(
 id bigint NOT NULL,
 notification_type notification_type,
 CONSTRAINT users_pkey PRIMARY KEY (id)
);

The jooq code generator outputs the following EnumType for the above and the generated POJOs reference this. 

public enum NotificationType implements EnumType {

 DEFAULT("DEFAULT"),

 EMAIL("EMAIL"),

 SMS("SMS");

 private final String literal;

 private NotificationType(String literal) {
 this.literal = literal;
 }

 /**
 * {@inheritDoc}
 */
 @Override
 public Schema getSchema() {
 return Public.PUBLIC;
 }

 /**
 * {@inheritDoc}
 */
 @Override
 public String getName() {
 return "notification_type";
 }

 /**
 * {@inheritDoc}
 */
 @Override
 public String getLiteral() {
 return literal;
 }
}

The issue I'm having is inserting using the generated DAOs insert(Users) method. Calling insert results in the following stack trace:

SEVERE: [127.0.0.1]:5701 [rx8081] [3.5.4] SQL [insert into "public"."users" ("id", "username", "password_hash", "email", "display_name", "first_name", "last_name", "phone", "birth_date", "notification_type", "pending_email") values (?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?)]; ERROR: column "notification_type" is of type notification_type but expression is of type character varying

Am I right in assuming that this should work? Any direction here would be much appreciated.

What jOOQ version are you using? There had been some bug fixes in this area, recently... jOOQ should render a cast around the String bind variable ?::enum_type_name

How did you fix this? I am getting the same error with Jooq = 3.0.0;

Thanks,

Hi Ganesh,

For starters... Please upgrade your jOOQ version and see if the problem persists :-)

I hope this helps,

Lukas

Hi Lukas,

Thanks for replying, I upgraded Jooq to 3.11 and still see the same issue. May be I am doing something wrong.

The post https://groups.google.com/forum/#!topic/jooq-user/K3sT3F5mnM0 has more details about my issue. Can you please help!

Thanks,

Ganesh
