SQL Query in C++ and Boost matrix libray

Hi all,
Suppose that one manages to query a series of 250 prices in c++ for 3 IDs such as:
ID1(1) | 1.0
ID1(250) |3.2
ID2(1) | 2.0
ID2(250)|4.0
ID3(1) |4.1
ID3(250) | 3.9
Does anyone know how to build a (250 * 3) price matrix for those IDs using Boost?
Any feedback would be very appreciated
Thanks a lot

Hi,
The description of your question is not clear and I am hard to get what you really want to do. Sorry about that.
Could you describe it more clearly ? it is better for me to help you solve your question.
In your statement, you may unclear how to use boost to create a metrix. It is a third party library, you should ask the question
on the office website of boost. And I can give you some suggestions.
First you should download boost and compile it.
Then you sould add to the additional include directories, like this:
Finally you could to learn how to use it on the boost office website. Here is the website:
http://www.boost.org/doc/libs/1_42_0/libs/numeric/ublas/doc/matrix.htm
and I have test the sample code in it and it works well.

I need help on how can i find out the size of SQL query before execution and after execution in java
The query can be any query select / insert / update
Can anyone help me if any system tables help to find out the required size i mentioned
Urgent help is required
Thanking in advance

I need the size in terms of bytes
like the rquirement is stated as below
select ................: 10 B , return 250 B
so i need size before and after execution in terms of bytes

SQL query with JSP and WML-parameters

Hey,
Could you help me?
I'm trying to do the following. WML deck card 1 send parameter to same WML deck's card help. I try to read the parameter with JSP in card help by putting the parameter to SQL query, but it doesn't work. I can read the parameter with WML in card help. I can also print the value of the parameter with JSP if I generate WML with JSP.
/*parameter sending from card 1 to card help*/
out.println("<go href='#helpcard'>");
out.println("<setvar name='valittukurssi' value='$(valittukurssi)'/>");
/*parameter read with WML in card help */
Valitse kurssi.
$valittukurssi
/'parameter read with JSP by generating WML with JSP*/
out.println("$valittukurssi");
/* SQL query with JSP */
ResultSet uudettulokset = uusilause.executeQuery("select * from kurssi where lyhenne='$valittukurssi'");
Thanks,
Rampe

You're problem is easy to fix. You're confusing WML variables with JSP variables. See below:
>
/*parameter sending from card 1 to card help*/
out.println("<go href='#helpcard'>");
out.println("<setvar name='valittukurssi'
value='$(valittukurssi)'/>");
Above you set a var that will work on the phone, not in JSP.
/*parameter read with WML in card help */
Valitse kurssi.
$valittukurssi
Yes the above does display the parameter, because it is a client side WML var, but you cannot use this variable in the JSP code (that's why your SWL fails).
/'parameter read with JSP by generating WML with
JSP*/
out.println("$valittukurssi");Here's you're problem, the above line is EXACTLY the same as the one before it. When the container parses through this JSP code it translates the above line to:
$valittukurssi on the WML page and the CLIENT uses it's local variable to display it.
What you need and want is to have a variable that can be used in JSP code and output to your WML page. Here's how it's done:
out.println("<go href='#helpcard'>");
String some_name = "valittukurssi";
out.println("<setvar name='"+some_name+"'
value='$("+some_name+")'/>");
//note that you may have to escape the ( and ) with a \
//so we displayed the variable above into the WML page, now we can use it in the SQL query:
/* SQL query with JSP */
ResultSet uudettulokset =
uusilause.executeQuery("select * from kurssi where
lyhenne='"+some_name+"'");//the end of the command is: " ' " ) ;

Sql query usig round and decode together

can i get one sql quer for returning whole number using round and decode function
eg:
the value 47
if value=47
then
the query should return 50
if the value =44
then
the quer should return 40
pls give me sql query for above example using round and decode function
Edited by: user11368167 on Jul 9, 2009 3:35 AM

A wild guess. If you want the ROUND Function to work only when your column value is 44 or 47 then you could use something like:
SQL> WITH test_tab AS
2       (SELECT 44 col_1
3          FROM DUAL
4        UNION ALL
5        SELECT 15 col_1
6          FROM DUAL
7        UNION ALL
8        SELECT 47 col_1
9          FROM DUAL
10        UNION ALL
11        SELECT 45 col_1
12          FROM DUAL)
13          -- end of test data
14 SELECT col_1,
15         DECODE (col_1,
16                 44, ROUND (col_1, -1),
17                 47, ROUND (col_1, -1),
18                 col_1
19                ) rounded_value
20    FROM test_tab
21 /
     COL_1 ROUNDED_VALUE
        44            40
        15            15
        47            50
        45            45
4 rows selected.
SQL> CASE Statement can be used as well instead of DECODE.
Good Luck,

Different LOV behavior between SQL query data model and data template

I have noticed different behavior when using parameters linked to list of values (LOV) of type menu with the multiple selection option enabled and a SQL query data model vs a data template. Here's the example because that first sentence was probably really confusing.
SQL Query:
select
plmc.MonthCode, plmc.ModalityDim, plmc.ModalityName,plmc.RegionDim
from
DataOut.dbo.PatientLabMonthlyCross plmc
where
plmc.MonthCode = 200202
and plmc.RegionDim = 1209
and 1 =
case
when coalesce(:modalityDim,null) is null
then 1
else
case
when plmc.ModalityDim in (:modalityDim)
then 1
else 0
end
end
Putting BI Publisher into debug mode, defining a data model of type SQL Query, defining a parameter called :modalityDim linked to a LOV that allows multiple selections, and selecting a couple of values from the LOV the output of the prepared statement is:
[081607_122647956][][STATEMENT] Sql Query : select
plmc.MonthCode,
plmc.ModalityDim,
plmc.ModalityName,
plmc.RegionDim
from
DataOut.dbo.PatientLabMonthlyCross plmc
where
plmc.MonthCode = 200202
and plmc.RegionDim = 1209
and 1 =
case
when coalesce(?,?,null) is null
then 1
else
case
when plmc.ModalityDim in (?,?)
then 1
else 0
end
end
[081607_122647956][][STATEMENT] 1:6
[081607_122647956][][STATEMENT] 2:7

[081607_122654713][][EVENT] Total Data Generation Time 7.0 seconds
Note how the bind variable :modalityDim was changed into two parameters in the prepared statement.
When I use this same SQL Query in a data template the output is:
[081607_012113018][][STATEMENT] Sql Query : select
plmc.MonthCode,
plmc.ModalityDim,
plmc.ModalityName,

and plmc.RegionDim = 1209
and 1 =
case
when coalesce(?,null) is null
then 1
else
case
when plmc.ModalityDim in (?)
then 1
else 0
end
end
[081607_012113018][][STATEMENT] 1:'6','7'
[081607_012113018][][STATEMENT] 2:'6','7'
[081607_012113574][][EXCEPTION] java.sql.SQLException: Syntax error converting the nvarchar value ''6','7'' to a column of data type int.
Note the exception because it is trying to convert the multiple parameter values.
Am I doing something completely wrong here? I really need to use a data template because I will need to link a couple of queries together from different database vendors.
-mark

This is for 10.1.3.4 - because in 11g every SQL query is automatially part of a data model.
In 10g SQL query is for simple unrelated SQL queries.
If you need to use advance features such as:
a) multiple SQL queries that are joined in master-detail relation ships
b) before/after report triggers
Then you will need to use the data template, which is an XML description
of the queries, links, and PL/SQL calls.
hope that helps,

Having troubles passing values of Shuttle control to SQL Query of Report and Chart Region

Hello,
I am very new to APEX and need help for one of the Pa.I have a shuttle control on my page which populates Categories. Once user selects Categories from this control, I wish to pass the values to following SQL query :
select * from emp_class where category IN ( LIST of VALUES FROM RIGHT SIDE SHUTTLE).
I tried various ways of doing this including writing a java scripts which reads shuttle value, converts it into below string
'Category1',Category2',Category3'. Then I set this value to a text box. And then I was expecting that below trcik would work
select * from emp_class where category IN (:TXT_VALUES)
I am sure this is not right way and hence its not working. Can you please guide me here with options?
Many Thanks,
Tush

Don't understand what this means. What is "Pa"?
select * from emp_class where category IN (:TXT_VALUES)
I am sure this is not right way and hence its not working. Can you please guide me here with options?
This is a common fallacy. In
select * from table where columnvalue in (7788, 7839, 7876)
(7788, 7839, 7876) is an expression list and the predicate is evaluated as a membership condition.
In
select * from table where columnvalue in :P1_X
:P1_X is a scalar string, incapable of containing multiple values.
In an APEX standard report, a PL/SQL function body returning an SQL query report source with lexical substitution can be used to produce a "varying IN-list":
return 'select * from table where columnvalue in (' || :P1_X || ')';
where P1_X contains fewer than 1000 values, has been sanitized for SQL injection, and string values are properly quoted.
Some people suggest the following approach, which will also work in APEX interactive reports:
select * from table where instr(':' || :P1_X || ':', ':' || columnvalue || ':') > 0
However this is non-performant as it eliminates the possibility of the optimizer using indexes or partition pruning in the execution plan.
See varying elements in IN list on Ask Tom, and emulating string-to-table functionality using sql for efficient solutions.

Sql query with conditions and calculations???

Hi,
how I can build a query with conditions and calculations?
E.g. I've got this table
Start          | End     |     Working Place     |     Mandatory
01-JAN-13 | 11-JAN-13 |     Office           |          1
14-JAN-13 | 25-JAN-13 |     Home Office      |     0
04-MRZ-13| 15-MRZ-13 |     Office           |          0
11-FEB-13 | 22-FEB-13 |     Office           |          1
Now if column working place=Office and column mandatory=0
the new column "price" has to calculate: (End-Start)* $25.00
and if working place=Office and column mandatory=1
the "price" column has to calculate: (End-Start)* $20.60
else $0.00
I tried it with the case statement but I didn't know how
to calculate my values and display it to the virtual column "price".
Something like
case
when Working_Place = 'Office' and Mandatory=1
     then ...
else '0.00'
end as PRICE
Or is it not possible?
Edited by: DB2000 on 12.03.2013 05:09

Use CASE:
select start_dt,
        end_dt,
        working_place,
        mandatory,
        case
          when working_place = 'Office' and mandatory = 0 then (end_dt - start_dt) * 25
          when working_place = 'Office' and mandatory = 1 then (end_dt - start_dt) * 20.60
          else 0
        end price
from tbl
START_DT END_DT    WORKING_PLA MANDATORY      PRICE
01-JAN-13 11-JAN-13 Office               1        206
14-JAN-13 25-JAN-13 Home Office          0          0
04-MAR-13 15-MAR-13 Office               0        275
11-FEB-13 22-FEB-13 Office               1      226.6

UPDATE SQL query using WHERE and a date/time data type... Multiple changes...

I'm using the LabView Database Connectivity Toolset and am using the following query...
UPDATE IndexStation
SET Signal_Size=200
WHERE 'StartTime=12:05:23'
Now the problem is that this command seems to update all rows in the table IndexStation... Not just specifically the row where StartTime=12:05:23
I have tries all sorts of {} [] / ' " around certain characters and column names but it always seems to update all rows...
I've begun to use the SQL query tab in Access to try and narrow down as to why this happens, but no luck!
Any ideas!?
Thanks,
Chris.

Chris Walter wrote:
I completely agree about the Microsoft issue.
But it seems no SQL based manual states that { } will provide a Date/Time constant.
Is this an NI only implementation? Because I can't seem to get it to function correctly within LabView or in any SQL query.
Chris.
There is nothing about the database toolkit in terms of SQL syntax that would be NI specific. The database Toolkit simply interfaces to MS ADO/DAO and the actual SQL syntax is usually implemented in the database driver or database itself although I wouldn't be surprised if ADO/DAO does at times munch a bit with that too.
The Database Toolkit definitely does not. So this might be a documentation error indeed. My understanding of SQL syntax is in fact rather limited so not sure which databases might use what delimiters to format date/time values. I know that SQL Server is rather tricky thanks to MS catering for the local date/time format in all their tools and the so called universal date/time format has borked on me on several occasions.

Tuning SQL query with SDO and Contains?

I'trying to optimize a query
with a sdo_filter and an intermedia_contains
on a 3.000.000 records table,
the query look like this
SELECT COUNT(*) FROM professionnel WHERE mdsys.sdo_filter(professionnel.coor_cart,mdsys.sdo_geometry(2003, null, null,mdsys.sdo_elem_info_array(1,1003,4),mdsys.sdo_ordinate_array(809990,2087279,778784,2087279,794387,2102882)),'querytype=window') = 'TRUE' AND professionnel.code_rubr ='12 3 30' AND CONTAINS(professionnel.Ctx,'PLOMBERIE within Nom and ( RUE within Adresse1 )',1)>0
and it takes 15s on a bi 750 pentium III with
1.5Go of memory running under 8.1.6 linux.
What can i do to improve this query time?

Hi Vincent,
We have patches for Oracle 8.1.6 Spatial
on NT and Solaris.
These patches include bug fixes and
performance enhancements.
We are in the process of making these patches
avaialble in a permanent place, but until then, I will temporarily put the patches on:
ftp://oracle-ftp.oracle.com/
Log in as anonymous and use your email for
password.
The patches are in /tmp/outgoing in:
NT816-000706.zip - NT patch
libordsdo.tar - Solaris patch
I recommend doing some analysis on
individual pieces of the query.
i.e. time the following:
1)
SELECT COUNT(*)
FROM professionnel
WHERE mdsys.sdo_filter(
professionnel.coor_cart,
mdsys.sdo_geometry(
2003, null, null,
mdsys.sdo_elem_info_array(1,1003,4),
mdsys.sdo_ordinate_array(
809990,2087279,
778784,2087279,
794387,2102882)),
'querytype=window') = 'TRUE';
2)
SELECT COUNT(*)
FROM professionnel
WHERE CONTAINS(professionnel.Ctx,
'PLOMBERIE within Nom and ( RUE within Adresse1)',1) >0;
You might want to try reorganizing the entire
query as follows (no promises).
If you contact me directly, I can try to
help to further tune the SQL.
Hope this helps. Thanks.
Dan

Learning SQL Query with JCheckBox and JButton

Hello,
I am learning how to access a very simple Access table. I am able to connect to the database and return a simple query. As I make it more complicated is where I have confused myself. The program is suppose to allow the user to pick any field they want to query using JCheckBox. After they have checked the fields off, the run query button is hit and outputs the results in a JOPtion Pane with a JTable. I am trying to do a test run and I can't make the query at least output something. If I can get any clues to the right direction would be appreciated. Thanks.

At present your query string is
"Select firstName from Address"
Instead of using the above hardcoded string, try to build the
query String using logic that checks which check boxes are selected
by the user.
Example..
String query = "SELECT ";
if (firstName.isSelected()) {
query = query + " firstName";
Be sure, you add the comma properly between two fields :-)

SQL-Query - AR Invoice and related AR Down Payment Invoices

Hello everybody,
I want to show all AR Down Payment Invoices related to a given AR Invoice, i.e. a query approximately in this form:
SELECT
T0.DocNum AS 'Invoice',
T0.DocDate AS 'Invoice Date',
T0.DocTotal AS 'Open Amount',
T1.<<DocNum>> AS 'Down Payment Invoice',
T1.<<DocDate>> AS 'Down Payment Invoice Date',
T1.<<Amount>> AS 'Down Payment Invoice Amount'
FROM
OINV T0 INNER JOIN <<Down Payment Invoices>> T1
ON T0.DocEntry = T1.<<DocEntry>>
WHERE
T0.DocNum = xxxxx
I want to know if such a table <<Down Payment Invoices>> exists and what its name is.
Thanks for your help!
Regards,
Frank Romeni

Thanks for the INV11 - but this table seems to be empty even for invoices we have related down payments, e.g.
SELECT
T0.DocNum, T0.DocTotal, T1.<<whatever you want>>
FROM
OINV T0 LEFT OUTER JOIN INV11 T1
ON T0.DocEntry = T1.DocEntry
WHERE
T0.DocNum = xxxxx
That INV11 is always empty I could see with SELECT * FROM INV11
Regards

P.S.: I only post questions to this forum when I analysed my problems and only if I couldn't find any further information in the helpfiles. With regard to your first hint to ODPI there is no reference to INV11 in the helpfiles.
With regard to your comments I feel impelled to to say that if my question is confusing you, then it seems that nobody has ever taught you that meaning can be taken from the context. Regarding the "street", you asked me to find something: Do not waste your time with talking precociously ...
If you should feel annoyed by my comments, we'd better stop this conversation. Otherwise let us fall back to a strictly factual exchange of information, OK? I am not willing to discuss this any further!

Need help in framing an SQL query - Sample data and output required is mentioned.

Sample data :
ID Region State
1 a A1
2 b A1
3 c B1
4 d B1
Result should be :
State Region1 Region2
A1 a b
B1 c d

create table #t (id int, region char(1),state char(2))
insert into #t values (1,'a','a1'),(2,'b','a1'),(3,'c','b1'),(4,'d','b1')
select state,
max(case when region in ('a','c') then region end) region1,
max(case when region in ('b','d') then region end) region2
from #t
group by state

005667821 LASER 173936.48 48 FEB-13
005231987 X-RAY1 120006 24 FEB-13My problem now is, the OTY field ist wrong it should count how often the equipment was in service in FEB-13 and group it by "MODELL" the MANUFACT field is not interesting for me, but this ist my problem, one Modell can have multible Manufacter and so i got a wrong count for my QTY.
The next step i need is to group the result also by Service type (annual or biennial), like this:
ART_NR MODELL TOTAL_PRICE QTY MONTH SERVICE_TYPE
018743356 VACCUM 1234.56 4 FEB-13 ANNUAL
018743356 VACCUM 4423.48 10 FEB-13 BIENNIAL

005667821 LASER 1123.77 22 FEB-13 BIENNIAL
005231987 X-RAY1 8966.12 6 FEB-13 ANNUAL
005231987 X-RAY1 7826.44 12 FEB-13 BIENNIALThis values are only out of my head, not the table, only to show what i need.
Thanks for your help.

Hi,
Here's one way:
WITH got_groups AS
 SELECT art_nr
 , TRUNC (status_date, 'MONTH') AS month
 , CASE
 WHEN UPPER (description) LIKE '%ANNUAL%'
 THEN 'ANNUAL'
 WHEN UPPER (description) LIKE '%BIENNIAL%'
 THEN 'BIENNIAL'
 END AS service_type
 , TO_NUMBER (price) AS price
 FROM table_1
 WHERE status_date >= DATE '2013-02-01'
 AND status_date < DATE '2013-03-01'
, table_2_summary AS
 SELECT DISTINCT art_nr, modell
 FROM table_2
SELECT g.art_nr
, s.modell
, ROUND ( SUM (g.price)
 , 2
 ) AS total_price
, COUNT (*) AS qty
, g.month
, service_type
FROM got_groups g
JOIN table_2_summary s ON s.art_nr = g.art_nr
GROUP BY g.art_nr
, s.modell
, g.month
, g.service_type
;The reason why your aggregates were originally too high is that you have a many-to-many relationship between the tables. The tables are related only by art_nr, but art_nr is not unique in either table. Look at art_nr '005231987', example. There ate 2 rows in table_1 with that art_nr, and 6 rows in table_2 with the same art_nr. If we join on art_nr, then both of the rows in table_1 will match each of the 6 rows in table_2, so the COUNT will be 2 * 6 = 12, and in the SUM, each of the numbers from table_1 will get added 6 times.
Why is table_2 designed the way it is? Cn there be multiple modells for the same art_nr? If so, what would you want for output? If there can only be 1 modell for each art_nr, then a better design would be to have a table that just had one row per art_nr, and included the modell column, and another table to show which manufacturers produce each art_nr. In this problem, you wouldn't need the manufacturers table, and the other table already has unique art_nrs, so you wouldn't need anything like the sub-query table_2_summary.
Don't store price in a VARCHAR2 column. Storing NUMBERs in a VARCHAR2 column is just asking for problems. Why not use a NUMBER column instead.
You'll notice that I used ROUND (SUM ... where you use SUM ( ROUND. The results might be a little different because of rounding errors. ROUND ( SUM only has to call ROUND once per group (5 times in this example) instead of once per row (16 times in this example). The less rounding you do, the less rounding error creeps in. Also, since there are fewer function calls, it's more convenient. (Of course, you'll never notice the difference between calling ROUND 5 times or 16 times, but in a real-life exampe, the difference could be between calling it 50 times or calling it 16000 times.) If you really need to use SUM (ROUND, you can.

ORACLE SQL Query with Parent and Child structure

I have 2 tables which are Account tbl and Customer tbl, the structure is like below:
Account tbl
Customer_ID Account_ID Parent_Account_ID
3780952 3780952 3780952
3780997 3780997 3780997

Customer tbl (Customer_Group have different value, but im only interest on Personal)
Customer_ID Customer_Group
3781004 Personal
3780997 Personal
3780952 PersonalThe rule to determine PS/NonPS, Principle, Supp as per below:
**PS/NonPs**
Customer_ID equal to Parent_Account and Parent_Account is unique (not exist more than 1) then NonPs.
Customer_ID equal to Parent_Account and Parent_Account is non unique OR - Customer_ID is not equal to Parent_Account then PS
**Principle** IF NonPS then Principle is Null IF PS - If Customer_ID equal to Parent_Account then Principle is Y else N
**Supp** IF NonPS then Supp is Null IF PS - If Customer_ID not equal to Parent_Account then supp is Y else N The final output should be like this
Customer_ID Account_ID Parent_Account_ID PS/NonPS Principle Supp
3780952 3780952 3780952 NonPS Null Null
3780997 3780997 3780997 PS Y N
