问题 The issue started when i installed the server version with already existing client version of Oracle 10g. Background : The Oracle client version 10g was installed (at c:/oracle) to connect to a database residing in other country. So we can just connect to it and have limited access to it. Path => c:/oracle/ora_client/network/admin/listener.ora So to work as admin I installed 10g server at the same location c:/oracle on windows. I can now work as server. Path => c:/oracle/product/db_1/network

问题 When I try to use WMSYS.WM_CONCAT with Oracle XE 10g, I receive a compilation error: ORA-00904: "WMSYS"."WM_CONCAT": invalid identifier . Can anyone verify that this is indeed due to XE lacking this (undocumented) feature? If so, is there anyway to enable it in XE? 回答1: I had found a couple reference sites, but had no luck enabling it. I ended up writing my own function to handle the concatenation. CREATE or replace FUNCTION CONCAT_LIST( cur SYS_REFCURSOR, sep Varchar2 ) RETURN VARCHAR2 IS

问题 For some period time of inactivity, connection to oracle database are dropped and this leads to error - > end-of-file on communication channel . 1) Is there any oracle settings on client machine (sqlnet.ora or some kind of environment variables) which could specify connection timeout and differs from client to client ? Or it could be client settings of some "heartbeat" feature (client sends packets in some interval), which prevent connection to be dropped by firewall ? 2) Where I can find

问题 I'm doing an audit of a system, which the developers insist is SQL injection proof. This they achieve by stripping out the single-quotes in the login form - but the code behind is not parameterized; it's still using literal SQL like so: username = username.Replace("'", ""); var sql = "select * from user where username = '" + username + "'"; Is this really secure? Is there another way of inserting a single quote, perhaps by using an escape character? The DB in use is Oracle 10g. 回答1: Have a

问题 Oracle 10g DB. I have a table called s_contact . This table has a field called person_uid . This person_uid field is a varchar2 but contains valid numbers for some rows and in-valid numbers for other rows. For instance, one row might have a person_uid of '2-lkjsdf' and another might be 1234567890. I want to return just the rows with valid numbers in person_uid. The SQL I am trying is... select person_uid from s_contact where decode(trim(translate(person_uid, '1234567890', ' ')), null, 'n', 'c
