Unable to set NULL value in a column with type uuid which is nullable in Postgresql using Node JS

I am using node pg client, and I have a table

create table test(
   id uuid not null constraint transactions_pkey primary key,
   name varchar(255),
   test_id uuid
);

I am trying to update test_id to NULL but I am unable to do so programmatically.

Here is my update query

dbo.query('UPDATE test SET test_id = $1 WHERE id = $2',['null','f2aasced-5633-419c-95d3-3868dd3c9c53'])

It gives me an error

error: invalid input syntax for type uuid: "NULL"

Solution

  • You just try to insert string 'null' into uuid column. Try 

    dbo.query('UPDATE test SET test_id = $1 WHERE id = $2',[null,'f2aasced-5633-419c-95d3-3868dd3c9c53'])
