Database Search Problem

Hey,
I am creating a database with a user profile, where a user can select their interests.
i.e
Golfing Yes/No
Movies Yes/No
Travelling Yes/No
So, there are 20 interests like that, and each of them is a boolean.
Would it be inefficient to create 20 boolean fields like that ?
I kinda thought that would be inefficient (not sure if it's true) and thought of a way to put it into the database as a BYTE(20) stream, like
1001010001011, where 1-yes, 0-no.
However the problem is.. what if I want to do a search where only the first question is yes, and all the other does not matter ?
For example.
I want to search for a string like 1????????????, where ? could be 0 or 1.
So here are my 2 questions:
Will I need to traverse the whole database that way ? (use BYTE(20))
or should I just code them as 20 separate booleans ?
thanks !
Dennis

G'day DennisMV,
I'd suggest 20 separate booleans. It may take some more space (however these are booleans, so the space would be extremely small!) . But it will save you alot of time writing code that you don't really need to. Also, hunting down small, sinister, evil bugs would be alot tougher using the stream. That's the direction i'd head in anyway.
Good Luck,
TimmyP

Multiple field database search problem... plz help me

Hi,
I have a search form with 6 search fields. 5 text boxes and one combo box. I want to search values from two tables based on this search keys. I am using 3 tables. Followings are the table structure....
comp_det
CREATE TABLE `comp_det` (`comp_id` INT( 11 ) NOT NULL AUTO_INCREMENT ,
`compname` VARCHAR( 100 ) NOT NULL ,
`address` VARCHAR( 100 ) NOT NULL ,
`city` VARCHAR( 100 ) NOT NULL ,
`state` VARCHAR( 100 ) NOT NULL ,
`membnum` VARCHAR( 100 ) NOT NULL ,
PRIMARY KEY ( `comp_id` )) TYPE = MYISAM ;
pro_det
CREATE TABLE `comp_det` (`comp_id` INT( 11 ) NOT NULL AUTO_INCREMENT , `pro_name` VARCHAR( 100 ) NOT NULL , PRIMARY KEY ( `pro_id` )) TYPE = MYISAM ;
comp_prod

These are the search key :
Company Name (compname from comp_det)
contact person (personname from comp_det)
city( city from comp_det)

Database search results

i have a master results page (aspVB) from Dreamweaver 8. have
search page from
WebAssist Database Search using advanced text search (single
search box)
question 1 - when a user hits 'enter' on the search page, all
records show,
no matter if there is any value in the search box or not. How
do you prevent
any records showing, if 'enter' is selected and the search
box is empty, and
if there is a value in the search box and 'enter' is
selected, show just the
results from the search box value?
question 2 - if more than one word is put in the search box,
such as, 'green
sol' the results show any thing with 'green' as well as
anything
with 'sol' and also anything with 'green sol'. how can you
just have the
results with 'green sol' and not 'green' or 'sol'. result
wanted is 'green
solutions' or 'green solar' or 'green sold'.
thanks for your help

Thank you for pointing out this problem. It has been fixed. (If you still see the wrong topic being linked to, try refreshing your browser. If it's still a problem, it might take a little while for the Database 11.2 documentation library to be updated on various systems worldwide. It did work just now for me.)

Capture database search string

Thanks to all who help,
I maintain a database search utility on our company Intranet that was developed using FrontPage (our only company standard development tool). The user enters a product code and initiates the search. When the results are found in the database, the original page reloads and the information about the product displays below the original. I have a "Print the results" button on the page that, at present, prints the entire page.
What I would like to be able to do is have the print button actually open another window that displays only the information that the user requested, so that they don't get my original page design (and all the unnecessary information) on their printout.
Would someone please help me to implement this change.
Thanks,
Bob

I don't know what you're talking about with back and front end of scripts, but if you think this is a Java-related question, then please post some Java code that you've tried to write to solve this problem, or some thoughts on what classes and methods might be used.
Also keep in mind that JavaScript is not Java and this forum is not relevant to JavaScript in any way.

Database termination Problem

Hi every body ..plz help me on this..
We are facing database termination problem in ECC6 production syste.
Database: Oracle 10.2, O/S: Windows 2003. Spam :27, SP level 13.
Error is:

O/S-Error: (OS 33) The process cannot access the file because another process has locked a portion of the file.
When we are performing backup then data base termination occuring freequently.
Give right solution as early as possible.

Hi,
Have a look at below snote which actually speaks about the oracle error codes
Snote : 546006
within the Snote it says :-
" If you cannot access a database file (for instance a data file, control file or RedoLog) for whatever reason, an ORA-270xx appears. The actual cause comes from additional error messages (usually in the operating system) that occur on ORA-270xx. "
And as per your last update
" ORA-00206: error in writing (block 3, # blocks 1) of control file
ORA-00202: control file: 'D:\ORACLE\P02\ORIGLOGB\CNTRL\CNTRLP02.DBF' "
i think there is problem accessing the database control file. Hence you are facing the above problem.
I think if you recreate your control file i think, it should resolve the problem.
Hope it will be helpful to resolve your problem.

Immediate HELP in Tomcat 5 to Postgresql 7.4 database connectivity problem

Hi,
I failed to connect Tomcat 5.0.24 with Postgresql
7.4.2. The files created by me and the changes i had
made in the existing files are rates.jsp,
conversionDAO.java, web.xml and server.xml. The error
message on the top of the rest of it was "The value of
useBean class attribute converter.conversionDAO is

database connectivity purpose in conversionDAO.java
cause the error. Another thing is Postgresql jdbc
driver is required to set in the CLASSPATH for the
java file to access the Postgresql database. I don't
know where should I put it in Tomcat for web
application. Anyway, I put it in
$CATALINA_HOME/shared/lib according the book i
refered. I do the database connectivity coding refer
to the Tomcat Kick Start book from Sams Publishing.

Hi Shriraj,
ensure that the installation path is correct. I only put /urs/sap/<SID> and you must put /usr/sap/<SID>/DV***/.
In my case with that the setup returns all in green.
I hope it helps you

SIMPLE Database Design Problem !

Mapping is a big problem for many complex applications.
So what happens if we put all the tables into one table called ENTITY?
I have more than 300 attributeTypes.And there will be lots of null values in the records of that single table as every entityType uses the same table.
Other than wasting space if I put a clustered index on my entityType coloumn in that table.What kind of performance penalties to I get?
Definition of the table
ENTITY
EntityID > uniqueidentifier
EntityType > Tells the entityTypeName
Name >
LastName >
CompanyName > 300 attributeTypes
OppurtunityPeriod >
PS:There is also another table called RELATION that points the relations between entities.

>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
check the coloumn with WHERE _entityType='PERSON'
as there is is clustered index on entityType...there
is NO performance decrease.
there is also a clustered index on RELATION table on
relationType
when we say WHERE _entityType ='PERSON' or
WHERE relationType='CONTACTMECHANISM'.
it scans the clustered index first.it acts like a
table as it is physically ordered.I was thinking in terms of using several conditions in the same select, such as
WHERE _entityType ='PERSON'
AND LastName LIKE 'A%' In your case you have to use at least two indices, and since your clustered index comes first ...
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
Have you ever thought of using constraints in your
modell? How would you realize those?
...in fact we did.We have arranged the generic object
model in an object database.The knowledge information
is held in the object database.So your relational database is used only as a "simple" storage, everything has go through your object database.
But the data schema is held in the RDBMS with code
generation that creates a schema to hold data.If you think that this approach makes sense, why not.
But in able to have a efficent mapping and a good
performance we have thought about building only one
table.The problem is we know we are losing some space
but the thing is harddisk is much cheaper than RAM
and CPU.So our trade off concerated on the storage
cost.But I still wonder if there is a point that I
have missed in terms performance?Just test your approach by using sufficiently data - only you know how many records you have to store in your modell.
PS: it is not wise effective using generic object
models also in object databases as CPU cost is a lot
when u are holding the data.I don't know if I'd have taken your approach - using two database systems to hold data and business logic.
PS2: RDBMS is a value based system where object
databases are identity based.we are trying to be in
the gray area of both worlds.Like I wrote: if your approach works and scales to the required size, why not? I would assume that you did a load test with your approach.
What I would question though is that your discussing a "SIMPLE Database Design" problem. I don't see anything simple in your approach when it comes to implementation.

The problem is ResultSet.next() is not called.
Try this and modify the table creation as you need.
ResultSetMetaData rsmd=rs.getMetaData();
int cols=rsmd.getColumnCount();
     while(rs.next()) {
          for(int i=1;i<=cols;i++)
                    col.addElement(rsmd.getColumnName(i));
                    rdata.addElement(rs.getString(i));
          rows.addElement(rdata);
Hope this helps

How do I create a simple database search

Either I'm being very stupid or all the manuals and books I'm
reading really are skirting round the obvious question of how do I
build a search page (using Dreamweaver 8) that searches a database
using only valid values previously fetched from the database. Can
anyone advise?
Example:
Say I've got a table called members which holds a list of
members of a gym. Say I want to offer my users a way of filtering
down the list of members by (say) home town and hair colour.
What I want to do is offer my users two lists which are
generated using Datasets: One listing all the unique hometowns of
my members and one listing unique hair colours. I want my users to
enter search criteia but only valid ones - so they must select from
the list of valid values I provide them with. I'll then filter my
main resulkts based on what they select.
But how do I do this? Not using URL variables obviously. And
not using Form variables as you can't list database items in a form
variable (can you?). I've got "DW 8: The Missing Manual" which I
was hoping would give me the answers I'm looking for but instead
seems to get very excited about the power of Dreamweaver 8 then
skirts round the fact that you can't use current database values to
do a database search!!! (unless I'm missing something that is)
While I'm at it - I'd idealy want to achieve all this on a
single page but I'm willing to concede on that if technology
predicts otherwise.
ASP.NET (VB)
Dreamweaver 8.0.2
Any guidance would be very welcome. (I'm new to all this by
the way)

> But how do I do this? Not using URL variables obviously.
Querystrings could be used if you wanted to. That'd be nice
so people could
bookmark the page.
> ASP.NET (VB)
Might be time to consider NOT using DW, as it no longer
supports ASP.net
But, in pseudo code:
onPageLoad:
- get list of hometowns
- populate hometown dropdown
- get list of hair colors
- populate hair color dropdown
onPostBack:
- check to see if there is a hometown selected
- check to see if there is a hair color selected
- if either of the above, modify the WHERE clause in your
SQL query to
reflect those values.
If you wanted to add querystrings, modify the logic as such:
onPageLoad:
- get list of hometowns
- populate hometowndropdown
- get list of hair colors
- populate hair color dropdown
- check for querystrings
- if they exist, grab them, modify the WHERE clause in your
SQL query to
reflect those values and show the results.
onPostBack:
- check to see if there is a hometown selected
- check to see if there is a hair color selected
- do a response.redirect to this page adding the appropriate
querystrings
if either of the above had values.

WLI 7.0 samples database setup problem

I have just installed WL Platform 7.0. I want to run the WLI samples and did the following:
1. Started "Integration Database Wizard" for WLI samples and performed "SwitchDB"
- provided valid database properties for oracle. Completed successfully - config.xml
for samples is updated.
2. Ran RunSamples script - Gives database connect problems and database is not created.
The user/pwd/machine name/SID are all correct.
I observed that as part of "RunSamples", it again invokes "SwitchDB" (command I see
is "switchdb oracle"). This resets the database properties in config.xml to the defaults
- so obviously this is causing the connection problem.
Pls let me know what is going wrong here?
Thanks

Garf,
You are correct in your analysis. When you run the 'RunSamples' script,
it will call switchdb and this causes the 'defaults' to be set in
config.xml. Running the wliconfig utility is the customer experience
BEA would like to have with regard to setting up the database. However,
the RunSamples script has not been updated to correctly reflect that the
customer would have already performed this step. When RunSamples calls
switchdb, it is getting the defaults from the following location:
<USER_DEFINED_DOMAIN>/dbInfo/<DATABASE>/setDBVars and setDBVarsExt files
So for example, if you accepted the default user directory and your
BEA_HOME is C:/bea and you were using the EAI Domain template calling
your domain eaidomain and your are using Oracle, you should update the
following files:
C:\bea\user_projects\eaidomain\dbInfo\oracle\setDBVars.cmd and
setDBVarsExt.cmd
Edit these files to reflect your DB connection properties.
When RunSamples calls switchdb, these properties will be used to update
the wliPool in config.xml. I hope this helps and sorry for the
inconvenience.
Cheers,
Chris

Database Searching Algorithms

Hi..
I have to do some research about database searching algorithms.
Would someone here help me and give a list of that algorithms and which one is the best.
What is the name of this algorithms which when u type in a key such "a" then it display a list of information that started with "a".

I guess I have more time than I thought... :)
Here is a full working example all in one class...
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
public class MAIN
     DefaultListModel model_my_list = new DefaultListModel();
    JList my_list = new JList(model_my_list);
     DefaultListModel model_list_of_finds = new DefaultListModel();
    JList list_of_finds = new JList(model_list_of_finds);
     JTextField search_box = new JTextField(20);
     JTextField add_box = new JTextField(20);
     public MAIN()
          JFrame frame = new JFrame( "Search test" );

Outlook 2010, Exchange 2010 - Searching Problems

Anyone out there able to help with some searching problems some of our users have been seeing?
Searching in OWA works fine but some people have problems when searching for older emails in Outlook. We've rebuilt Outlook profiles, rebuilt the windows index's (which seems to work but only temporarily). If there's a way to schedule the Windows index to
rebuild every night or once week, I'd be very happy to test that out but haven't been able to figure out how to do that.
Anyone have any other ideas?

Hi,
It seems something keeps corrupting the index... Run Anti-virus program and Malicious Software Removal Tool to scan your system, check if there's any virus or malware that may cause the index issue.
If this issue persists, please also go to File tab ->
Options -> Search -> Indexing Options
-> Advanced -> Click Troubleshoot search and indexing, to do some troubleshooting steps to find the possible cause.
I hope this helps.

How to chart database search results?

I'm new to Macs and Appleworks. I want to make a graph/chart of numbers that come from summary fields of a database search. Do I somehow link the database search results to a spreadsheet? Can I put the graph on a database report page? Thanks.

Maybe this will help.
You can create a bar chart this way.
You have some summary fields to be charted, call them sum1, sum2, etc.
Create another summary field for each that you have. The basic formula will be:
LEFT("||||||||||||||||||||||||||||||||||",SUM('sum1'))
This will give a number of line characters to match the sums. Position these fields to form a chart. You can modify the font and style, etc.
There're also some variations. If your totals are large, you could divide the final parameter by something:
LEFT("||||||||||||||||||||||||||||||||||",SUM('sum1')/2)
And even multiply by something if your totals are small.
This is using the standard line character. You could also use dingbats - the "n" will give a solid square: LEFT("nnnnnnnnnnn",SUM('sum1'))
Additionally, to fill gaps between characters, you can create two chart fields for each total and overlap them.
Now, these are summary fields and so need to be on the summary part of the layout, and you must be in Page View to see.
