Referencing a char column in another query

HI
I have 2 queries. My child query returns char data which needs to be referenced in the main query.
Is it possible to access this data from my main query.
I know its possible with numbers using summary cols.
TIA
TIM

You can reference a single value of the child query using the "first/Last" summary functions in a summary column in the master query. The datatype of the column doesn't matter.

Reference columns from another query

I've made XML data template in Report Builder, which consists of multiple data queries and groups. When I use for each XML structure in Word template builder to obtain data, I get data only from one data query, and blanks for fields that I referenced from another group.
Is there any way to solve that problem.
Thanks in advanced for the answers.

It seems to me that you are trying to get to a higher/parent element from within a lower/child group. So, use the ../ notation to get up to an element in a parent group. And add ../ as you go higher and higher. ex. <?../../CHECK_DATE?> Obviously, for referencing lower group, you just open the group with a for-each.
Make it a habit to open and close your groups for ease of readability.

Access Summary column in a query

Hi All,
I am new to oracle reports. I am using report builder 10.1.2.0.2.
I have a summary column in my report. I would like to use this summary column in another query.
if is use this column directly in the query, i am getting the below error:
"Field 'F1' references column '<summary column name>' at a frequency below its group. "
Both these fields are in the same frame. In the object navigator, both are displayed under the same group name.
please let me know if there any way to access summary columns in another query.
Thanks.

You can use a field from one query in another query as parameter, i.e. preceded by colon. To do this first create link of "Group to Query" type between the first query's group where the summary column is, and the second query.

Querying CHAR columns with character length semantics unreliable

Hi again,
It appears that there is a bug in the JDBC drivers whereby it is highly unlikely that the values of CHAR columns that use character length semantics can be accurately queried using ResultSet.getString(). Instead, the drivers return the value padded with space (0x#20) characters out to a number of bytes equal to the number of characters multiplied by 4. The number of bytes varies depending on the number and size of any non-ascii characters stored in the column.
For instance, if I have a CHAR(1) column, a value of 'a' will return 'a ' (4 characters/bytes are returned), a value of '\u00E0' will return '\u00E0 ' (3 characters / 4 bytes), and a value of '\uE000' will return '\uE000 ' (2 characters / 4 bytes).
I'm currently using version 9.2.0.3 of the standalone drivers (ojdbc.jar) with JDK 1.4.1_04 on Redhat Linux 9, connecting to Oracle 9.2.0.2.0 running on Solaris.
The following sample code can be used to demonstrate the problem (where the DDL at the top of the file must be executed first):
import java.sql.*;
import java.util.*;
This sample generates another bug in the Oracle JDBC drivers where it is not
possible to query the values of CHAR columns that use character length semantics
and are NOT full of non-ascii characters. The inclusion of the VARCHAR2 column
is just a control.
CREATE TABLE TMP2
TMP_ID NUMBER(10) NOT NULL PRIMARY KEY,

FYI, this has been mentioned as early as November last year:
String with length 1 became 4 when nls_lang_semantics=CHAR
and was also brought up in Feburary:

Result of an SQL query as a Column name of another query

Hi Friends,
Can we use a result of a SQL Query as a column name of another table to retrieve data. If so please help me.
For eg :
I have a table where is store numbers;
select col1 from table1 where col1='5';
and i have another table where .. this value of col is a column name..
select ( select col1 from table1 where col1='5') from table2;
Thanks in advance.

Thanks in advance.Do you really mean that?
select col1 from table1 where col1='5';That query will always return either '5' or nothing. Whatever you're trying to accomplish with that, you can do with an EXISTS query.
Perhaps you meant to reference two different columns in that query:
select col1 from table1 where col2='5';In that case, sorry, no, you can't do that without resorting to dynamic SQL.
If the same column is used throughout the query (but could change every time you run the query), then the dynamic SQL might be pretty easy. In SQL*Plus, for example, you could use substitution variables, defined in another query at run-time.
If there are only a few possible values that the sub-query could possibly return, and you know what they all are, then you can fake a dynamic query like this:
SELECT     CASE     ( SELECT col1
            FROM       table1
            WHERE       col2     = '5'
          WHEN 'BONUS'     THEN bonus
          WHEN 'COMM'     THEN comm
          WHEN 'SAL'     THEN sal
     END     AS col1
FROM     table2
;Sorry to give such a vague answer, but it's the best I can do with the information I have.
It would help if you posted a little sample data (CREATE TABLE and INSERT statments for both tables), and the results you want to get from that data. If you want to pass a parameter to the query, give the results you want for a couple of different parameters.

New custom column in a query

Hi experts,
I am doing a query and I need to do something that I am not sure if it can be done. I have one characteristic (0COUNTRY) in the query and one variable to filter by Sales Organization. What I need to do is to have a new column in the query that will show Local market in case 0COUNTRY is the same as the Sales Organization country attribute, and Export market when it is different. Does anybody know if this can be done in BeX analyzer?
Any hint would be appreciated.
Thanks and regards,

Hi,
U can achieve this by using virtual characterstics.Add another characterstics in the cube with length 20 char (Say ZTEXT).
Code in the exit RSR00002 with program ZXRSRU02 for virtual characterstics.
Here u can put the logic as follows:
Read value 0COUNTRY compare the value with SALESORG 0country attrtibute value from master data table.
if same ZTEXT = 'Local market
else.
ZTEXT = 'Export market
There will be some performance issue but if the requirement like this u can try with this.
Thanks,
Debasish

How can I Move data from one column to another in my access table?

I have two columns, one that stores current month’s data and one that stores last month’s data. Every month data from column 2 (this month’s data) needs to be moved to column 1 that holds last month’s data. I then null out column 2 so I can accumulates this month’s data.
I understand how to drop a column or add a column, how do I transfer data from one column to another.
Here is my trial code:
<cfquery name="qQueryChangeColumnName" datasource="#dsn#">
ALTER TABLE leaderboard
UPDATE leaderboard SET points2 = points3
</cfquery>
Unfortunately, I get the following error:
Error Executing Database Query.
[Macromedia][SequeLink JDBC Driver][ODBC Socket][Microsoft][ODBC Microsoft Access Driver] Syntax error in ALTER TABLE statement.
How can I transfer my data with the alter table method?

I looked up the Access SQL reference (which is probably a
good place to start when having issues with Access SQL), and
it suggests you probably need a WHERE clause in there.
I agree the documentation is a good place to start. But you should not need a WHERE clause here.
Too few parameters. Expected 1.
If you run the SQL directly in Access, what are the results? At the very least, it should provide a more informative error message..

Can we use Result from another query in Webi using Bex uery universe?

Hi,
Can we use Result from another query filter option in Webi to create a report using a Bex Query universe?
I need to create a report using two universes, one is Bex Query Universe and the other is Orcle universe. I have two queries, one is using Oracle universe; the other using Bex Query universe. I need to pass the Oracle data from the Oracle query to the Bex Query query to get the matched data from SAP Bex query.
I used Result from another query in the query filter panel for the query using Bex query universe. But I got an error saying that 'A filter contains a wrong value. you cannot run this query. (Error: WIS 00007). The data used in the filter on both sides are the same. they are char.
I have tested by using two queries from the same Bex query universe to see if the Result from another query filter option works. And I got the same error.
Has anyone run into the same issue and if this is possible and what should be the solution?
Thanks in advance!
Edited by: BO_Haiyan on Oct 6, 2010 3:47 PM

In that situation:
Create two queries : Oracle and BW query.
@ Report:
As you have to see result set from both the Dataproviders, correct? To achieve thise one must have common dimension objects to merge them at report and use Objects those are coming from both queries to use them in single Table/Report.
Unless you don't use Merge Dimensions, you don't get a chane to use both queries objects in single Table/Report. (It will give tooltip saying: You can't drop here -- Incompatable Objects)
In case, if you don't have common dimensions, change object definitions to Detail objects, for those required.
Hope it helps you.
Thank You!!

Need to compare values in two columns of one table against values in two columns in another table

Hi, as the title reads, I'm looking for an approach that will allow me to compare values in two columns of one table against values in two columns in another table.
Say, for instance, here are my tables:
Table1:
Server,Login
ABCDEF,JOHN
ABCDEF,JANE
FEDCBA,SEAN
FEDCBA,SHAWN
Table2:
Server,Login
ABCDEF,JOHN
ABCDEF,JANE
FEDCBA,SHAWN
In comparing the two tables, I'd like my query to report the rows in table1 NOT found in table2. In this case, it'll be the 3rd row of table one:
Server,Login
FEDCBA,SEAN
Thanks.

create table Table1([Server] varchar(50), Login varchar(50))
Insert into Table1 values ('ABCDEF','JOHN'),('ABCDEF','JANE'),('FEDCBA','SEAN'),('FEDCBA','SHAWN')
create table Table2([Server] varchar(50), Login varchar(50))
Insert into Table2 values ('ABCDEF','JOHN'),('ABCDEF','JANE'), ('FEDCBA','SHAWN')
select [Server] ,Login from Table1
Except
select [Server] ,Login from Table2
select [Server] ,Login from Table1 t1
where not exists(Select 1 from Table2 where t1.[Server] = t1.[Server] AND Login=t1.Login)
drop table Table1,Table2

ADD a column in a query

Hi
I want to add a column in my query.
This column is the sum of the net value and the tax ..please how can I do this without refering to ABAP development..
thanks in advance

This is not an SD question and you might want to use Search (and include other forums) in the future.
There is no ABAP needed for such basic calculations in queries. In SQ01, this can be done in the 'Select field' screen (it's the 3rd screen where you select which fields will be included in the query.
First, assign short names to your Net Value and Tax fields. Go to the menu Edit -> Short Names -> Turn On/off. This should open another column to the right from the field names. Enter the names, say NET and TAX.
Then create a new local field. Same menu, Edit -> Local field -> Create. Give the field some name (TOTAL), assign a type ('Same field as -> use Net field or whatever is suitable). Enter formula NET + TAX and save.

TopLink JPA - trailing spaces on Char column

Gurus,
In JDBC you use the following to ignore trailing spaces when querying on Char column:
OracleConnection conn = (OracleConnection) c;
conn.setDefaultFixedString(true);
How to achieve this using TopLink JPA?
Thanks much,
Nicky

Nicky,
I believe you would need to do this in API. Ideally setting these configurations on the properties of the JDBC connection pool is easier but if you wish to do it with TopLink Essentials I would use a session event listener's postAcquireConnection to customize it.
In the persistence.xml you will need to configure your persistence unit to use a session customer like:
        <property name="toplink.session.customizer" value = "mypackage.JDBCConnectionConfig"/>Then you will need to implement this customizer and include it on the classpath of your application:
public class JDBCConnectionConfig implements SessionCustomizer {
    public void customize(Session session) {
        session.getEventManager().addListener(new JDBCConfigEventListener());
    class JDBCConfigEventListener extends SessionEventAdapter {
        public void postAcquireConnection(SessionEvent event) {
            Connection conn = ((DatabaseAccessor) event.getResult()).getConnection();
            OracleConnection oconn = (OracleConnection) conn;
            oconn.setDefaultFixedString(true);
Note: I did not see setDefaultFixedString in the most recent version of the Oracle JDBC driver
I would definitely look into configuring your data source's connection pool with this property enabled before adding this event listener.

Query result filter another query

Hello Guru
I want to create a query A (List of PM_ORDER) filter by status.
and another query B based on the list of query A.
Query A became "filter" of query B.
How handle this ?

Hi Laurent,
You can attempt this using replacememtn path variable for the char you need to filter by. This is called Result Set Query. See here for details:

PreparedStatement and CHAR columns

Hi
I am having troubles using preparedStatements on tables with columns of type CHAR:
My table has a column of type CHAR(3). The data in this column is 0,1,2 or three characters long.
My query contains this column in the WHERE clause in the from "WHERE colName = ?".
The problem is now, that I have to use a String in the pstmt.setString(1, str) statement that is exactly 3 characters long. Otherwise I don't get any result.
If I use a 2 char string i get nothing. But with a 'normal' statement or in SQL*Plus it works perfectly fine.
Of course, I could trim() my column or fill the string up to be always 3 chars, but I think that's not state of the art.
Any other solutions?
Thanks in advance.

What you describe is the ANSI behavior of a CHAR column. VARCHAR columns can match on any length (and can be any length up to the maximum or the column constrint limit), but a char column is required to be blank padded. If you must use CHAR then write a function to automatically pad the string for you so that it will match.

Unicode String Issue while Using Results from Another Query

Hi All,
In a webi report i have 2 queries say Sales Out and Investment. I need to have only those chains which are in Investement in Sales Out.
So in Sales Out query i am using the option Results from another Query. The Chain values are in Unicode format.
Though in universe i have Set Parameter Unicode_String ='Yes', this does not get applied when using option Results from another Query.
Is there any solution to resolve this problem.
Thanks

BEX Query - Run time char InfoObjects manipulation for query results

Hello Experts,
Iam working on BEX queries to meet following requirements,
1) Display only first 2 char of an InfoObject in the query results. Actual infoprovider has 24 char for this InfoObject. Example: Summary code FABCDXXXX.. But we want to show only 'FA' in query results
2) We split a 120 char description into two 60 char InfoObjects, we need to concatenate the split char into one for query result display
3) We need to show a specific hierarchy level, nothing before or after. For example: Eighth level for a cost element hierarchy.
4) We need to show a constant in a column (which is not there in the table)
We are planning to use both BEX analyzer and Crystal for the reports.
I read in one of the thread that we can use formula variables/Customer exit for this but iam not very clear, if you know how to do it or if you have any step by step procedure, can you please pass it to me. Thanks in advance for your help.
Regards,
Raman

Thanks for quick response. We have users who need BEX analyzer, is there any way to handle the above requirments for BEX analyzer.
