RE: will the Return Order of rows change with time ?
Thanks Richard good explanation .. Your answer has cleared all my doubts . thanks again to all who replied to this query. ratnesh -Original Message- Richard Sent: Wednesday, October 23, 2002 1:14 PM To: Multiple recipients of list ORACLE-L I understand what you are saying. Most people responded that there is no guarantee because that is the true answer. In a sense you are correct - if nothing changes the optimisers approach then in all likelyhood the rows will come back in the same order each time... However you are inserting rows into the table, so there is a good chance that the optimiser may change it's mind at some point in time. Also, most of our comments have been about returning the rows in the same sequence each time... Promising that this sequence will also match the order in which they are inserted becomes even more difficult. Even today the query may be using an index (depending on the where clause) which may result in a traversal of your table that does not match the insertion order. For example, if you had an index on delivery_date and your query was select * where delivery_date sysdate then the result set will most likely appear sorted by delivery_date, since the index is sorted. Delivery_date may have nothing to do with the order of inserting rows into your table however, since different products may have different delivery schedules. Therefore what your are asking for is really quite unpredictable. Indeed, I have seen cases where index hints are used to return rows in a specific order without using an order by clause, and these rows definitely don't match their insertion order. Using a hint to force the order of a result set makes me cringe - although it does perform very fast, and can be combined with where rownum 100 to return the earliest 100 rows without even reading more than 100 rows from the table - a cute trick. hth, Mark.

RE: locking issues in web based applications
Dennis , thanks for your suggestions. It seems detection is the only viable option to avoid locking. i'll try to get the suggested book from somewhere . ratnesh -Original Message- WILLIAMS Sent: Tuesday, July 23, 2002 9:08 PM To: Multiple recipients of list ORACLE-L Ratnesh I assume you are using the JDBC interface, rather than J2EE. You may want to consider buying the book Java Programming with Oracle JDBC by Donald Bales. He devotes a chapter to this subject. One issue he raises that will limit your options is whether you have other applications besides your Web-based application accessing this database. If not, that gives you additional flexibility. Bales distinguishes between locking and detection. He contends that locking alone does not solve the problem of multiuser data access integrity, and offers several examples to support his contention. He then outlines 3 methods for employing detection. He defines detection as the ability to detect if data you are about to modify has changed since the point when you selected it to be updated. 1. Pessimistic. Use an updatestamp 2. Pessimistic. Compare all the columns in the table or attributes of an object with their original values. 3. Optimistic. Compare only modified columns or attributes in a WHERE clause. I wish I could speak from experience, but I think this author has studied this issue in more detail than I could.

There was a bug in 1 version where the domain would get selected from the default_domain present in sqlnet.ora HTH, Bruce Reardon -Original Message- Sent: Thursday, 11 July 2002 16:13 Hi many thanks to all who replied to my query. I was able to solve the problem by changing the dblink create stmt. It seems the user had created the links as CREATE PUBLIC DATABASE LINK abc.WORLD CONNECT TO username IDENTIFIED BY pwd USING 'dbname.world' ; I recreated the dblinks as CREATE PUBLIC DATABASE LINK abc CONNECT TO username IDENTIFIED BY pwd USING 'dbname.world' ; However , Kevin's reply has resulted in me finding another problem. When i did a select * from global_name on db A , i get dbname.world . but when i do the same on db B , i get only dbname ??? i crosschecked all init.ora , sqlnet tnsnames params on both A B ,and i did not find any differences. db_domain for both A B is world, global_names is FALSE. db_name, instance_name service_names are consistent across both A B. According to oradocs , global_name is a view for the init.ora param GLOBAL_NAME. Why is this diff coming and how do i resolve it. thanks again ratnesh -Original Message- Sent: Wednesday, July 10, 2002 10:23 PM I had this problem in the past at a site where we were switching from .world to named domains. I can't remember exactly where I found it but I remember that the method Oracle used to determining the dblink domain was funky. On both databases, check select * from global_name and compare the result to select * from dba_db_links. It seems to me that the domain extension on the global_name was used as the default extension when creating links. Caused me no end of heartburn -- nothing I couldn't work around, but more work arounds than I was happy with. Hope my memory is sufficient since I don't have the problem at my current site. Kevin Kennedy First Point Energy Corporation -Original Message- Sent: Wednesday, July 10, 2002 5:53 AM hi i have 3 databases(A,B,X) on 3 diff boxes. i have created 1 dblink each from A to X from B to X. The syntax for dblink creation is exactly same for both dblinks. I am able to query from dblink A-X as select * from user.table@dblinkAX but when i try to query from dblink B-X as select * from user.table@dblinkBX i get the foll error Error: ORA-02019: connection description for remote database not found When i modify my query by suffixing '.world' as select * from [EMAIL PROTECTED] , the query works fine. I have compared the entries in init,sqlnet,tnsnmames,listener files on both A B databases and they are absolutely similar . i was thinking that the domain or globalnames parameters might be diff on A B , but they are absolutely same . any suggestions are most welcome ... thanks in advance ratnesh --- Ratnesh Kumar Singh Sr. Software Engineer Patni Computer Systems Ltd TTC Mahape , Navi Mumbai Work : (91 22) 7611090/110/128/350 Ext. 2107 Home : (91 22) 8662162 http://www.patni.com World-Wide Partnerships.

Re: Optimizer and function based index
Oracle function based indexes do not work if OR clause is used .This is mentioned in the oracle docs. I think if u use union clause it may work out . try and see... --- Seefelt, Beth [EMAIL PROTECTED] wrote: Hi everybody, I'm hoping someone can help me understand this. I have this query - SELECT ORDERID FROM WWW SHOPCART WHERE UPPER(MEMBERNAME) ='19891' ; I added an index on the column UPPER(MEMBERNAME) and it works great. I have another query - SELECT ORDERID FROM WWW SHOPCART WHERE UPPER(MEMBERNAME) ='19891' OR UPPER(MEMBERNAME)='198915'; and this query will not use the index at all. I can't understand why the optimizer won't choose to use the function based index when there is an OR clause. I've tried the same query with just MEMBERNAME= and using an index on MEMBERNAME, and the optimizer will use the index if I OR my criteria together. Any ideas?
