解释计划对于 select 工作正常但不适用于 Merge 语句
Explain plan for is working fine for select but not for Merge statements
我正在尝试分析我编写的合并语句的执行计划，但是当我 运行 它在数据库中时它抛出 01031.00000 - “权限不足”错误。当用于 select 语句时，相同的解释计划工作正常并且计划成功生成。任何人都可以帮助解释为什么仅合并语句就很高兴吗？
要执行 EXPLAIN PLAN 语句，您需要 与 执行 语句相同的 权限。
因此，如果您仅对合并的 table 授予 SELECT，您将无法执行 MERGE 和 执行EXPLAIN PLAN 声明。
这里是相关的引用形式 Documentation
You must also have the privileges necessary to execute the SQL statement for which you are determining the execution plan. If the SQL statement accesses a view, then you must have privileges to access any tables and views on which the view is based. If the view is based on another view that is based on a table, then you must have privileges to access both the other view and its underlying table.
