查询在SQL * Plus中有效，但在JDBC中失败，并带有ORA-00911异常

Question

I'm trying to track the amount of redo being generated during a database session with the following query:

SELECT a.name, b.VALUE
  FROM v$statname a, v$mystat b
  WHERE a.statistic# = b.statistic# AND a.name = 'redo size';

This query works directly in SQL*Plus and Toad, but I get an ORA-00911 exception using JDBC, and I've narrowed it down to the "statistic#" column name.

How do I get around this?

Answer 1

The column name statistic# is not the problem.

My bet is that you also send the terminating ; from inside your Java program.

But you may not include the the ; when executing a SQL statement through JDBC (at least not in Oracle and some other DBMS).

Remove the ; from your SQL String and it should be fine.

Answer 2

将其用双引号引起来-这应该使您可以在Oracle中将字段称为任何内容

Answer 3

Switch on JDBC logging, check your driver documentation for how to do this. In the JDBC log you see the actual statement prepared and executed in the DB. This eliminates one possible cause for the error.
