Hi all,
I am using query something like that
select * from table1 where column1 = 'value1' and column2 = 'value2';
and I have created the index like this
create index index1
on table1(
column2
);
i have used only one column because column2 is usually unique and can only sometimes repeat
Will the query will use the index or do i have to create index with both columns? I am using Oracle database.
Regards
Shajeel

The program I'm working on has a screen full of project data. The client wants to be able to run a "Google like" text search across all the text/lookup fields to return matching projects. Of course they want to be able to search on phrases also, matching all words, some words, etc.
The data is spread across around 10 tables. My first thought was to use Contains() in some capacity, but the db isn't full-text indexed. I'm not sure it would help if it was.
My remaining options seem to be:
1. Concatenate all the string info for each record into a field. Build up a custom select string with multiple Like searches, one for each word in the phrase to search. Run this with exec. Pretty sure the performance will suck on this one.
or
2. Concatenate all the string info for each record into a field. Select this data into a temp table and use a cursor to delete the non-matches for each word in the phrase to search. Pretty sure the performance will suck on this one also.
Are there any options I'm missing or has anyone got any better ideas?

Well, it ranges from sucky to extremely sucky, depending on the implementation. I'm hoping to write an article about this topic in the weekend 
A fast tip; why not create a shadow-table that holds the same columns, as varchar-types? It's a lot faster than converting everything on the fly, and you can let the server insert a varchar-record with a trigger from the original table.
Good luck

There's a new article (not by me btw), containing a simple search-engine algorithm[^] that could be adapted to work with SQL CE
--edit--
This[^] is the article that you wanted

Are you sure that columns RoomID and Avaliable exists in table PresidentialSuite?
For more info check this google result[^].

yes, they exist.
and RoomID is primary key.
and if i modify the select statement (i just added braces and no other changes)
select (PresidentialSuite.RoomID,PresidentialSuite.DateWhenFilled,PresidentialSuite.DateWhenFree,PresidentialSuite.TimeForHouseKeeping)
then iam getting this error:
Msg 102, Level 15, State 1, Line 14
Incorrect syntax near ','.

yeah, it has from clause and where clause too...
INSERT INTO HouseKeeping (RoomID,DateWhenFilled,DateWhenFree,TimeForHouseKeeping)
select PresidentialSuite.RoomID,PresidentialSuite.DateWhenFilled,PresidentialSuite.DateWhenFree,PresidentialSuite.TimeForHouseKeeping
FROM PresidentialSuite
where PresidentialSuite.Available='no';
|
|
|
|
|
try this
INSERT INTO HouseKeeping <br />
select RoomID,DateWhenFilled,DateWhenFree,TimeForHouseKeeping<br />
FROM PresidentialSuite<br />
where Available='no';

The last select statement should return you two inserted rows in table HouseKeeping.

Hi everyone,
I have a simple table called test with two columns, ID and Name.. I'm trying the following but it doesnt work.
INSERT INTO TEST VALUES(SELECT SEQ_INDI.NEXTVAL FROM DUAL,SELECT NAME FROM TEST);
How would you fill its values again (duplicate them) without violating the primary key constraint?? I tried to use a sequence but how would you do it?? and if you would use a sequence, what your sql statement would look like??
Thank you guys!

Hi,
The only privilege I assigned to a newly created user "U" was CREATE SESSION, then I had to assign DBA to it and create a test table then I revoked the DBA Role from the SYS user, now it shows me that the only privilege and role I have for this user is CREATE SESSION
SQL> SELECT PRIVILEGE FROM DBA_SYS_PRIVS WHERE GRANTEE = 'U';
PRIVILEGE
----------------------------------------
CREATE SESSION
SQL> SELECT GRANTED_ROLE FROM DBA_ROLE_PRIVS WHERE GRANTEE = 'U';
no rows selected
SQL>
why can I still select, update and delete that table though I didnt grant this privileges to this table and how can I revoke something I didnt even granted??
Please help guys
