如果我从我的 Oracle 客户端 (SQL Developer) 运行此 SQL 语句，它就可以工作：

insert into Person (Name) select 'Bob' from dual

如果我通过 Spring JDBC 发出它，它也可以工作，而不使用KeyHolder：

final PreparedStatementCreator psc = new PreparedStatementCreator() {

    @Override
    public PreparedStatement createPreparedStatement(Connection con)
        throws SQLException
    {
        return con.prepareStatement(
                "insert into Person (Name) select 'Bob' from dual");
    }
};
jdbcOperations.update(psc);

但是我需要使用 KeyHolder 来获取新插入行的 ID。如果我将上面的代码更改为使用 KeyHolder，如下所示：

final KeyHolder keyHolder = new GeneratedKeyHolder();
final PreparedStatementCreator psc = new PreparedStatementCreator() {

    @Override
    public PreparedStatement createPreparedStatement(Connection con)
        throws SQLException
    {
        return con.prepareStatement(
            "insert into Person (Name) select 'Bob' from dual",
            new String[] {"PersonID"});
    }
};
jdbcOperations.update(psc, keyHolder);

...然后我收到此错误：

FWIW，如果我执行 INSERT ... VALUES 而不是 INSERT ... SELECT 一切都很好（尽管这对我没有帮助，因为我需要选择一些东西）：

final KeyHolder keyHolder = new GeneratedKeyHolder();
final PreparedStatementCreator psc = new PreparedStatementCreator() {

    @Override
    public PreparedStatement createPreparedStatement(Connection con)
        throws SQLException
    {
        return con.prepareStatement(
            "insert into Person (Name) values ('Bob')",
            new String[] {"PersonID"});
    }
};
jdbcOperations.update(psc, keyHolder);

我在用着：

  • Spring JDBC 3.0.3.RELEASE
  • JDBC驱动：ojdbc6.jar版本11.2.0.1.0
  • RDBMS：Oracle9i 版本 9.2.0.5.0 - 生产
  • 公共-dbcp 1.4

注意我的应用程序需要使用标准 SQL 才能保持 db-neutral，这排除了任何特定于 Oracle 的 SQL（在现实生活中我不会从“双重”中选择）。

谢谢你的帮助。

java.sql.Connection.prepareStatement(java.lang.String, int)接口清晰

创建一个默认的 PreparedStatement 对象，该对象能够检索自动生成的键

所以你使用了错误的方法。尝试

return con.prepareStatement(
        "insert into Person (Name) select 'Bob' from dual",
        Statement.RETURN_GENERATED_KEYS);

反而

怎么样

INSERT INTO blah b (blah1, blah2, blah3)
VALUES (?, ?, ?) RETURNING b.id INTO ?";

Oracle JDBC 驱动程序不支持此功能

我怀疑使用带有 INSERT SELECT 语句的 KeyHolder 不受支持，因为 select 理论上可以选择多行，如果这样做，将无法将这些多个键返回到单个 KeyHolder 中。对于您要完成的工作，简单地使用 select 语句后跟 insert 语句可能会更容易。
