| * `/*T! Specific code */`: This syntax can only be parsed and executed by TiDB, and be ignored in other databases. | ||
| * `/*T![feature_id] Specific code */`: This syntax is used to ensure compatibility between different versions of TiDB. TiDB can parse the SQL fragment in this comment only if it implements the corresponding feature of `feature_id` in the current version. For example, as the `AUTO_RANDOM` feature is introduced in v3.1.1, this version of TiDB can parse `/*T![auto_rand] auto_random */` into `auto_random`. Because the `AUTO_RANDOM` feature is not implemented in v3.0.0, the SQL statement fragment above is ignored. |
