Hint Specifying Not to Use Global Plan Cache

Function

When global plan cache is enabled, you can use the no_gpc hint to force a single query statement not to share the plan cache globally. Only the plan cache within the current session lifecycle is retained.

The current feature is a lab feature. Contact Huawei technical support before using it.
