CREATE TABLE t0 (
c0 DECIMAL(20,0) UNSIGNED,
c1 CHAR(10) DEFAULT '{',
c2 FLOAT UNSIGNED GENERATED ALWAYS AS (c0) VIRTUAL NOT NULL UNIQUE
);
INSERT IGNORE INTO t0(c1, c0) VALUES ('3', NULL), ('&', -679917749);

✔️ Expected Behavior

Statements execute successfully.

❌ Actual Behavior

ERROR 4016 (HY000): Internal error

Start by reproducing the three SQL statements on OceanBase 5.7.25-OceanBase_CE-v4.5.1.0 under the reported Ubuntu environment, focusing on the generated column, unsigned values, and ON DUPLICATE KEY UPDATE. Done means the statements execute successfully without ERROR 4016 (HY000): Internal error.
