Question

我得到错误：

ORA-03001: unimplemented feature
ORA-06512: at "SYS.CHANGE_SSAN", line 127
ORA-06512: at line 2
Process exited.

在这一行：

  alter_constraints_disable(hosm_list.hosm);

这是程序：

PROCEDURE alter_constraints_disable (hosm_cd   IN VARCHAR2)

IS
    BEGIN

    for constraint_list IN (select table_name, constraint_name 
                                   from dba_constraints 
                                   where owner=hosm_cd 
                                   and constraint_name in ('List of constraints removed for space.'))
    LOOP
        execute immediate 'alter table '||hosm_cd||'.'||constraint_list.table_name||' DISABLE constraint '||constraint_list.constraint_name;
    END LOOP;
END;

问题似乎来自下一行，而不是调用alter_constraints_disable。

执行立即'select person_id批量收集到'_ | hosm_list.hosm ||'。dod_per命令中的dup_ssan由1 asc';

我是否缺少关于批量收集的内容

更好的异常处理将准确揭示导致错误的原因。运行此修改版本，然后发布输出。

CREATE OR REPLACE PROCEDURE alter_constraints_disable (hosm_cd IN VARCHAR2)
IS
    BEGIN

    for constraint_list IN (select table_name, constraint_name 
                                   from dba_constraints 
                                   where owner=hosm_cd 
                                   and constraint_name in ('List of constraints removed for space.'))
    LOOP
        DECLARE
            v_sql varchar2(32767);
        BEGIN
            execute immediate 'alter table '||hosm_cd||'.'||constraint_list.table_name||
                ' DISABLE constraint '||constraint_list.constraint_name;
        EXCEPTION WHEN OTHERS THEN
            dbms_output.put_line('Error with '||constraint_list.table_name||'.'||
                constraint_list.constraint_name);
            v_sql := dbms_metadata.get_ddl('TABLE', constraint_list.table_name, hosm_cd);
            dbms_output.put_line('Table that caused the error:'||chr(10)||v_sql);
            raise;
        END;
    END LOOP;
END;

<强>更新

bulk collect into不应位于动态SQL字符串中。这是一个例子：

create table dod_per as select level person_id from dual connect by level <= 100;

declare
    type dup_ssan_type is table of number;
    dup_ssan dup_ssan_type;
    v_owner varchar2(30) := user;
begin
    execute immediate 'select person_id from '||v_owner||'.dod_per order by 1 asc'
    bulk collect into dup_ssan;
end;
/

DBA_CONSTRAINTS仅适用于具有DBA角色的用户。尝试使用ALL_CONSTRAINTS或USER_CONSTRAINTS。还要确保执行该过程的用户具有ALTER CONSTRAINT权限。

您使用的是哪个版本的Oracle？如果是快递版，那么一些功能将无法启用，因为您需要许可证，但据我记忆，禁用/启用约束不是其中之一。

有趣的是，当我的查询有一个带有额外尾随双引号的标识符时，我也通过ODP.NET提供程序收到此错误（类似这样）

SELECT "Field1" "Alias1", "Field2" "Alias2"
FROM "SomeSchema"."SomeTable"" -- <- extra quote
WHERE "SomeField" = 'SomeCriteria'

简单错误的奇怪错误。
