How to represent multiple values in one column

Hi,
I need some help in designing a schema for this problem.
I have :
- 4 domains
- In each domain there will be many groups
- users belong to multiple groups in multiple domains
Eg.
user1 might be in groups g1, g2 and g3 in domains d1, d2
In a text file I represent it like this:
user1 | d1 | g1,g2,g3
user2 | d2 | g1, g2
etc.,
How do design a schema for this. I don't like the idea of having comma
separated values in columns.
Thanks.

Good instincts. You don't want to have comma-separated values in a column, that violates basic normalization rules.
You would probably want something like this
CREATE TABLE usr (
user_pk
user_id
CREATE TABLE grp (
group_pk
group_id
CREATE TABLE domain (
domain_pk,
domain_name
CREATE TABLE domain_group (
domain_pk,
group_pk
CREATE TABLE user_group (
user_pk,
group_pk
)where you create separate tables that map different things to each other. domain_group shows which groups are associated with a particular domain, user_group shows which users are associated with a particular group.

Multiple value in one column issue

Dear proffessionals,

1. Query select cr_pjid from acc_users where username='ACCBTPS121' give result
CR_PJID
'26','63'2. Query select * from acc_accbtp_nova_view where ed_id=2 and to_char(pj_id) in ('26','63'); return 186 rows.
3. Query: select * from acc_accbtp_nova_view where ed_id=2 and
              to_char(pj_id) in (select cr_pjid
              from acc_users
              where username='ACCBTPS121'); doesn't return any row... :(
Could anyone help me ?
Thx in advance,

After researching, I think that the best idea is to create another table with multiple rows and different values for one column...

Retrieving multiple values from one column in SELECT statement

Hi,
I have a slight dilemma in that I'm trying to pull down all the values from a column from a select statement that includes some JOINS in it.
If I run the query at the SQL Plus prompt, it pulls back all the values/rows.
When I run the select (and prepared ) statement in my JSP, it only pulls back one of the 4 values I'm trying to retrieve.
e.g.
at the DB level :
SELECT role_name, CC_ID FROM votetbl a
INNER JOIN APPROVERS b ON
a.BUSVP = b.BUSVP AND
a.BRANCH = b.BRANCH
WHERE CC_ID = 1688this will return:
ROLE_NAME CC_ID
ops 1688
ops 1688
comply 1688
legal 1688
comply 1688
When run in my JSP, like so:
String primID3a = request.getParameter("primID");
Statement stmtovoter = connection.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE, ResultSet.CONCUR_READ_ONLY);
String prepvotSQL = "SELECT role_name, CC_ID FROM votetbl a INNER JOIN APPROVERS b ON a.BUSVP = b.BUSVP AND " +
"a.BRANCH = b.BRANCH WHERE CC_ID = ?";
PreparedStatement prepvotstmt = connection.prepareStatement(prepvotSQL);
prepvotstmt.setString(1, primID3a);
ResultSet rest3 = prepvotstmt.executeQuery();
rest3.next();
String votecat = rest3.getString(1);
out.println("Vote category: "+votecat);I only get ops returned.
Do I need to run an enumerator? Or reqest.getParameterValues or use a while statement around the results set?
Any feedback and direction here is welcomed!
Thanks!

Actually, I tried looping and still only get 1, but returned several times.
i.e.
PreparedStatement prepvotstmt = connection.prepareStatement(prepvotSQL);
prepvotstmt.setString(1, primID3a);
ResultSet rest3 = prepvotstmt.executeQuery();
rest3.next();
String votecat = rest3.getString(1);
while (rest3.next()) {
out.print("category roles "+votecat);
}then I get returned the following:
admincategory roles admincategory roles admincategory roles admincategory roles admincategory roles admincategory roles admincategory roles admincategory roles admincategory roles admincategory roles admincategory roles admin
like so.
Where as at the DB level I get
ROLE_NAME CC_ID
admin 1688
ops 1688
ops 1688
ops 1688
ops 1688
ops 1688
ops 1688
ops 1688
risk 1688
comply 1688
legal 1688
legal 1688
ops 1688
comply 1688
Maybe the while should go around the getString(1) designation? But I was thinking I'd tried that and gotten invalid cursor error
Something is definitely amiss, between the prepared statement in the servlet and the SELECT statement at the DB level.
I can totally hardcode the statement in the servlet or JSP and it will return one value potentially several times, but only one.
Other times, it will not return a value at all, even though one resides in the db.
Yet go to the DB/SQL Plus prompt and it returns perfectly. I can simply copy and paste the SELECT statement from the out.print line I made and it works like a champ in SQL Plus. Any ideas why the same exact thing cannot return the proper values within the servlet/JSP?
Yeeeeeeesh!!! : (

How to set multiple values in one context-attribute

Hi all,
Anybody knows a possibility to set multiple Values to a context-attribute?
I know it how to get it with the following code:
String break[]= request.getParameterValues("break");
Now I want to do something like:
request.setParameterValues(break[no]);
where no is a counter in a loop.
With the Method setAttribute(), I overwrite the previous inserted value.
Thanx
Robert

I have not explizit declared break as an array.
It is the Context- Attribute I want to send. I thaught that I can use it as an array in the same way I can do it when I send Data from an HTML- Form (with multiple values) to an servlet.
I don't know how to declare the Attribute explizit as an array.
that it is you wanted to know?
I think my main problem is to get an array from the servlet to the jsp. Is there an other possibility (other than via Context-Attributes) to do that?
thanx
robert

How to create multiple links in one column

Could someone please help me with creating 2 different links in one column as below.
I enclosed is the screen shot of my current application view... I would like to put the link one below the other in one column instead in two different columns.
Table Name - SR_PROCESS

When you have a problem you'll get a faster, more effective response by including as much relevant information as possible upfront. This should include:

With APEX we're also fortunate to have a great resource in apex.oracle.com where we can reproduce and share problems. Reproducing things there is the best way to troubleshoot most issues, especially those relating to layout and visual formatting. If you expect a detailed answer then it's appropriate for you to take on a significant part of the effort by getting as far as possible with an example of the problem on apex.oracle.com before asking for assistance with specific issues, which we can then see at first hand.

Try something like

From two given tables, how do you fetch the values from two columns using values from one column(get values from col.A if col.A is not null and get values from col.B if col.A is null)?

From two given tables, how do you fetch the values from two columns using values from one column(get values from col.A if col.A is not null and get values from col.B if col.A is null)?

Hi,
Use NVL or COALESCE:
NVL (col_a, col_b)
Returns col_a if col_a is not NULL; otherwise, it returns col_b.
Col_a and col_b must have similar (if not identical) datatypes; for example, if col_a is a DATE, then col_b can be another DATE or it can be a TIMESTAMP, but it can't be a VARCHAR2.
For more about NVL and COALESCE, see the SQL Language manual: http://docs.oracle.com/cd/E11882_01/server.112/e26088/functions119.htm#sthref1310
I hope this answers your question.
If not, post a little sample data (CREATE TABLE and INSERT statements, relevant columns only) for all tables involved, and also post the results you want from that data.
Explain, using specific examples, how you get those results from that data.
Always say which version of Oracle you're using (e.g., 11.2.0.2.0).

How to get all the values in one column of a JTable

How to get all the values in one column of a JTable as a Collection of String.
I don;t want to write a for loop to say getValueAt(row, 1) eg for 2nd column.

I don;t want to write a for loop to say getValueAt(row, 1) eg for 2nd column. You could always write a custom TableModel that stores the data in the format you want it. It would probably be about 50 lines of code. Or you could write a loop in 3 lines of code. I'll let you decide which approach you want to take.

How do you lookup multiple values in different columns based on variable criteria?

Essentially, I'd like to be able to do a Vlookup but instead of searching for one value only, search for multiple values in separate columns. A smaller version of my current spreadsheet as an example...
Attack Type ->
Fire
Water
Grass
Fire
1/2x
2x
1/2x
Water
1/2x
1/2x
2x
Grass
2x
1/2x
1/2x
Fire/Water
1/4x
1x
1x
Fire/Grass
1x
1x
1/4x
Grass/Water
1x
1/4x
1x
The headers are the attack types and the list of types to the left are the receiving Pokemon. Fire does half damage (1/2x) to fire types, Water does double damage (2x) to fire types, etc. I'd like to be able to search for specific damages for each type. For example, I'd like to find a Typing that recieves half (1/2x) damage from Fire-type attacks but also recieves double (2x) from Grass-type attacks. I do want more than just two search criteria though seeing as the actual table is much, much larger.
I've tried assigning number values to each damage multiplier and then merging all of them together for a specific typing and doing a VLOOKUP based on checkboxes determining what damage multiplier I want in a few specific types, the rest being filled in to the standard of 1x but the result isn't correct most of the time.

Hi Mitchell,
VLOOKUP can be set for accept either an 'exact match' or a 'close match'. Your 17 digit 'number' is actually a 17 character text string (Numbers can handle numbers to a precision of only 15 places). Provided all 17 digits are present, sorting should be the same as for numerical values—the leftmost character is the most significant.
As a text string, your 'number' is sorted/evaluated alphabetically. A 'close match' accepts the 'largest value that is less than or equal to the search value'.
If your search term is 000200000 (a 9 character string), several 'wrong' answers will fit the 'close match' criteria, including all of those listed below:
000200000 (the 'correct' match)
0000xxxxx (x may be any of the three acceptable values)
0001xxxxx (x may be any of the three acceptable values)
The main problem here is that digits in a number (or characters in a text string) have decreasing significance related to their distance from the beginning of the string/number. You want a search in which each character has the same significance as each of the others when compared to the search key. To do that, you need to compare each character in the search string with the character in the same position in the similar string for each type of Pokemon, then take a count of the matches or a sum of the differences.
Here's one approach:
Column A contains labels.
Column B, the 17 digit search term, created in whatever manner you wish, and the similar 17 digit string for each of the characters.
Columns C through S contains a formula that detines, using subtraction, the difference between each digit of the search term and the corresponding digit of each character's profile.
Column C uses SUM() to calculate the total of columns C to S for each row.
T1 uses =MIN(T) to calculate "least different" profile.
Column A is a Header column; Row 1 is a Header row.
Formulas:
C2, and filled right to S2, then down to the last row of data:
=ABS(MID($B$1,COLUMN()-2,1)-MID($B2,COLUMN()-2,1))
T1: =MIN(T)
T2, and filled down column T: =SUM(C2:S2)
The conditional formatting rule set for all body cells in column T is shown below the table.
This may be enough to get you started. Formulas can be tweaked to produce results more closely matching what you're looking for, if necessary.

Barry

How to get multiple values using HttpSession.getAttribute(java.lang.String)

Hey Guys
I'm trying to find a way to get multiple values using the following method
HttpSession.getAttribute(java.lang.String)
Here's the scenerio. Its a already written application and now i'm trying to make some changes. earlier in the jsp page a combo box was used and value was retrieved in the servlet using the getAttribute method of Session. Now I'm using a html multiple selection list and have to retrieve all the values selected in the list in the servlet. Can anyone please suggest me how to do that. HTTPRequest class has a method getParameterValues which will let me do that but i have to do is using HTTPSession.
Thanks for your time to read this

I'm not sure what you are trying to do. You can only use session.getAttribute to retrieve something that has already been stored in the session with a previous setAttribute. If you need to store multiple values under one attribute name using setAttribute, you can store an array, or an ArrayList or whatever type of Collection you want. The request.getParameterValues method is the only way you can retrieve form parameters than can have multiple values. If the servlet hasn't already processed these parameters and put them into the session for you, you have to use request.getParameterValues.

How to select multiple values from the parameters in BI Publisher report

How to select multiple values from the parameter drop down in BI Publisher, and how to handle this mulitple values from the report sql...

Hi kishore,
I have used all the steps as you mentioned in your previous reply....including checking Mulitple Selection Check Box..
Iam able to get the results when I am selecting one value..
and also I am able to handle multiple values the in the query by using IN :Parameter, but seems when we select more than one value from the parameter drop down i think the Bi Publisher is sending the values in concatenated form something ilke
ex: "'ACCOUNT','HR','SALES'" ,and when trying to display the parameters values in the output, its throwing the error as 'missing right paranthesis' ....on the whole do you have any solution which would handle
1.Single selection.
2.Multiple selection.
3.'ALL' Values.
4.Separating the concatenated string into individual strings and dispaly them on the output of the report..etc..in case of Mulitple selection.
Ex:
Concatenated String from BI Publisher:"'ACCOUNT','HR','SALES'"
Expected Output on the report:ACCOUNT,HR,SALES
reply to this would be much appreciated....
thanks,

This is not a java question and it is not even a problem: your only problem is
1) lack of knowledge
2) lack of interest to find a manual
But you are going to have to change both by actually reading a book or a manual that explains the stored procedure language of SQL Server. It is the same as Sybase I think, so you could also look for a manual for that DBMS.
