This repo demonstrates a bug in the sqlboiler code generation tool. The generated Upsert test fails.

To demonstrate the bug, clone this repo and run:

docker-compose up -d
sqlboiler psql --wipe
go test ./models/...

You should see the following output:

--- FAIL: TestUpsert (0.00s)
    --- FAIL: TestUpsert/Examples (0.00s)
        example_test.go:722: Unable to upsert Example: models: unable to upsert example: pq: cannot insert a non-DEFAULT value into column "id"
        example_test.go:727: models: failed to count example rows: pq: current transaction is aborted, commands ignored until end of transaction block
        example_test.go:730: want one record, got: 0

The bug occurs because the generated upsert test provides a value for the id field:

id INT GENERATED ALWAYS AS IDENTITY

From the postgres docs:

In an INSERT command, if ALWAYS is selected, a user-specified value is only accepted if the INSERT statement specifies OVERRIDING SYSTEM VALUE.

Versions used:

  • SQLBoiler: v4.8.3
  • Postgres: 14
  • Go: go1.17.6 darwin/arm64
