Query with `RANDOM()` cannot be generated

[erendogan51]

Version

1.28.0

What happened?

Any query i try to generate where a random() function is contained fails to be found and generated. And on a side note, the sqlc playground throws an 500 error response when the version is higher than 1.25.

Relevant log output

# package 
query.sql:3:8: function random(unknown, unknown) does not exist

Database schema

CREATE TABLE foo (
  id   BIGSERIAL PRIMARY KEY,
  value int not null
);

SQL queries

-- name: InsertBarV0 :exec
insert into foo(value)
SELECT random(-100000, -30000);
         
-- name: InsertBarV1 :exec
insert into foo(value)
SELECT random(-100000, -30000)
from generate_series(sqlc.arg('intervalStart')::timestamptz, sqlc.arg('intervalEnd')::timestamptz,
                     sqlc.arg('interval')) g
         cross join generate_series(0, sqlc.arg('multiplier')::int) gg;

PostgreSQL

What type of code are you generating?

Go

[jakoguta]

The function RANDOM() in PostgreSQL does not take arguments. So the error function random(unknown, unknown) does not exist is valid.

[erendogan51]

The function RANDOM() in PostgreSQL does not take arguments. So the error function random(unknown, unknown) does not exist is valid.

It was added in Postgres 17.

[jakoguta]

This is correct, PostgreSQL 17 has the function random(min, max).
