Syntax to manually insert a UUID value in Postgres

Question

I have a table that was created as such:

CREATE TABLE IF NOT EXISTS DIM_Jour (
    jour_id uuid NOT NULL,
    AAAA int,
    MM int,
    JJ int,
    Jour_Semaine int,
    Num_Semaine int,

    PRIMARY KEY (jour_id)
);

I'm trying to manually insert some value for testing purposes. I know that eventually I would need to use a UUID generator.

INSERT INTO DIM_Jour (jour_id, AAAA, MM, JJ, Jour_Semaine, Num_Semaine) VALUES (
    292a485f-a56a-4938-8f1a-bbbbbbbbbbb1,
    2020,
    11,
    19,
    4,
    47
);

I get this error (or similar)

ERROR:  syntax error at or near "a485f"
 LINE 3:  292a485f-a56a-4938-8f1a-bbbbbbbbbbb1,
             ^

I've tried the different formats mentioned in the Postgres documentation, but it seems like it doesn't except any format. Is it a stupid syntax issue or am I missing something here? What is the correct syntax?

Answer 1

You could pass it as a string literal and have the database implicitly convert it to a UUID:

INSERT INTO DIM_Jour (jour_id, AAAA, MM, JJ, Jour_Semaine, Num_Semaine) VALUES (
    '292a485f-a56a-4938-8f1a-bbbbbbbbbbb1',
    2020,
    11,
    19,
    4,
    47
);

But it's probably a good practice to be explicit about it and perform the cast yourself

INSERT INTO DIM_Jour (jour_id, AAAA, MM, JJ, Jour_Semaine, Num_Semaine) VALUES (
    '292a485f-a56a-4938-8f1a-bbbbbbbbbbb1'::UUID,
    2020,
    11,
    19,
    4,
    47
);
