ORA-48938: View select column count differs from select alias list ORACLE 报错 故障修复 远程处理

文档解释

ORA-48938: View select column count differs from select alias list

Cause: The view alias list has a different number of fields than the select list”

Action: Change the alias list or view select statement

这是由于查询时使用了不同类型的列,列的别名数量和列的计数数量不一致所导致的一种ORA-48938错误。

官方解释

常见案例

一般处理方法及步骤

1. 检查SELECT语句,确认混合使用不同类型的列。

2. 使用CASE(条件)结构来替换这些混合的不同类型的列,或者使用CAST函数将它们转换为一致的类型。

3. 重新运行SELECT语句,确保可以正常执行。
