In Oracle-compatible stored programs, variable declarations for RECORD types, associative-array types, and SYS_REFCURSOR currently accept data-type attributes that are meaningless for those types: length, scale/decimals, CHARACTER SET / COLLATE, and REF_SYSTEM_ID.
They should fail instead of being accepted, with ER_UNSUPPORTED_DATA_TYPE_ATTRIBUTE (message that the data type does not support that attribute).
Reproduce with CREATE PROCEDURE bodies that declare:
- a RECORD TYPE alias used as a variable type with (n), (n,m), REF_SYSTEM_ID=…, CHARACTER SET …, and COLLATE …;
- an associative-array TYPE alias with the same attributes;
- SYS_REFCURSOR with the same attributes (sql_mode=ORACLE).
Acceptance: each case errors as above; valid declarations without those attributes keep working. Attribute checks must apply for both user TYPE definitions and named/plugin types used in the same declaration syntax—not only one path.
Work only inside this repository checkout. Make the code change the task
describes, keeping the diff focused — no drive-by refactors.
When you are done, leave your changes committed or in the working tree;
they are collected automatically.
Stay on this snapshot checkout (`task/ycb_server_cbfcb303c056f`). Never checkout, pull, or rebase onto `main`. That branch is a README-only orphan.
Stay on this HEAD. Do not fetch another default branch. Push only on the Cursor-created `crazy-cursor/…` side branch from this HEAD.
Some past runs of this task were launched with a different prompt (the prompt template changed since, or those runs predate this benchmark's stored prompt). Each run persists the exact prompt it sent at launch — that per-launch record is the audit trail; this page shows only the current one.
