ORA-14752: Interval expression is not a constant of the correct type ORACLE 报错 故障修复 远程处理

文档解释

ORA-14752: Interval expression is not a constant of the correct type

Cause: You attempted to use either a nonconstant interval or an interval whose data type does not correspond to the partitioning column

Action: Use only constant expressions for the interval. If the data type of partitioning column is numeric, the interval must be a numeric constant. If the data type is of type date/time, the interval must be a constant of interval type

ORA-14752表示间隔表达式的类型错误,它可能有以下两个原因:

1)给定的间隔表达式不是正确类型的常量。

2)给定的间隔表达式类型为空或无效。

官方解释

此错误消息通常将在您尝试在SQL语句中使用常量作为间隔表达式时显示,并且这个间隔表达式的类型不正确,缺少信息或无效。

常见案例

RMAN恢复操作中可能会出现ORA-14752错误,如下所示:

RMAN> RESTORE DATABASE;

Starting restore at 17-JUL-19
