Sql statement in Summary folders...

Hi ,
Is there a way to see the exact sql statement produced when a summary folder has been created....????
NOTE: I use Oracle Discoverer 10.1.2. version on XP machine.
Thanks ,
Simon

Interesting question.
I take it that means that if you use a summary folder in Disco, then the SQL Inspector won't show the summary folder redirection in the SQL?

Summary Folders vs Materialized Views

Hi everybody,
Which is best to use summary folders/tables or materialized views? In other words , can materialized views replace the summary folders or vice versa?
In which situations are we using materialized views and in which other situations are we using summary tables created by Discoverer..????
Thanks , a lot

Hi ,
I found at least one hindrance in creating a summary table from Discoverer Admin.
Whereas , in SQL , i can write freely , for example....
CREATE MATERIALIZED VIEW MV_DINAMIKOTITA_KLINON_TMHMA
BUILD IMMEDIATE
REFRESH START WITH TO_DATE(ADD_MONTHS(TRUNC(SYSDATE, 'RRRR'), 12) ,'DD/MM/RRRR')
NEXT TRUNC(ADD_MONTHS(SYSDATE,12),'RRRR')
AS
SELECT TO_CHAR(SYSDATE,'RRRR') YEAR, CODE_TMHMATA , COUNT(BED) DINAMIKOTITA
FROM BEDS
GROUP BY TO_CHAR(SYSDATE,'RRRR') , CODE_TMHMATA
where column 'BED' is of varchar2 datatype
in Discoverer , the clause count(bed) is not produced when i select the table beds , as expected....because is of varchar2 datatype.
When I add a custom item COUNT_BEDS which is a function count(beds) and trying to add it in the summary table an error message apperas:
'That item have default aggregate of Detail and cannot be added to the summary....'.
Having read the documetation and examples about summary tables , i found that at least one of the columns of the imported tables or views or mv's must be in number datatype , in order to be created as a summary table.....
In my case this means that the column 'BED' should be of number datatype not varchar2...
Are the above notes correct and how can i create the above displayed SQL statement as summary table...
Thanks , a lot , anyway

Execute Stored Procedure SQL Statement with Parameter from Cell

I would like to know if there is a way to pass the parameters to SQL Statement of Power Query. For example, I have a SQL Statement as follows:
EXEC [dbo].[spReportBuilder]
@Report = N'Revenue Summary',
@Year = N'2014',
@Period = N'11'
I would like to know if it is possible to pass the @Report, @Year, @Period values from cells in the workbook, preferably without vba.
Thanks

rtisserand,
Here is the M code:
let
IDValue = Excel.CurrentWorkbook(){[Name="YearTable"]}[Content],
Source = Sql.Database("localhost", "AdventureWorks2012", [Query="EXEC [dbo].[spReportBuilder] @Report = N'Revenue Summary', @Year = N'" & Number.ToText(IDValue[ID]{0}) & "', @Period = N'11'"])
in
Source
Some notes:
You have to reference the excel query from another step in the query or you will get the following error:
Formula.Firewall: Query <>something<> references other queries or steps and so may not directly access a data source. Please rebuild this data combination.
I only did the parameter for one value.
Hope this helps.

Multiple Executions Plans for the same SQL statement

Dear experts,
awrsqrpt.sql is showing multiple executions plans for a single SQL statement. How is it possible that one SQL statement will have multiple Executions Plans within the same AWR report.

Dear experts,
awrsqrpt.sql is showing multiple executions plans for a single SQL statement. How is it possible that one SQL statement will have multiple Executions Plans within the same AWR report.If you're using bind variables and you've histograms on your columns which can be created by default in 10g due to the "SIZE AUTO" default "method_opt" parameter of DBMS_STATS.GATHER__STATS it is quite normal that you get different execution plans for the same SQL statement. Depending on the values passed when the statement is hard parsed (this feature is called "bind variable peeking" and enabled by default since 9i) an execution plan is determined and re-used for all further executions of the same "shared" SQL statement.
If now your statement ages out of the shared pool or is invalidated due to some DDL or statistics gathering activity it will be re-parsed and again the values passed in that particular moment will determine the execution plan. If you have skewed data distribution and a histogram in place that reflects that skewness you might get different execution plans depending on the actual values used.
Since this "flip-flop" behaviour can sometimes be counter-productive if you're unlucky and the values used to hard parse the statement leading to a plan that is unsuitable for the majority of values used afterwards, 11g introduced the "adaptive" cursor sharing that attempts to detect such a situation and can automatically re-evaluate the execution plan of the statement.

How to dynamically create sql statement for Defaulting Segment Values?

Hi,
Navigation:
1) Descriptive/Segments
2) Query for DFF to be modified
3) Uncheck “Freeze Flexfield Definition”
4) (B) Segments
5) Segments Summary form opens
6) (B) open - Segments form opens
Now, here I want to specify Default type as "SQL Statement" and in the default value field I want to use SQL statement with parameters (to evaluate the default value).
The parameters should be pass at runtime from the form in which we have this DFF. The parameters value should be one of the values which get evaluated at runtime in the form window.
Please suggest how we can achieve this?
Or is there any alternative to achieve this?
Thanks!!
Regards,
Narender

Jason,
it is possible, though not so simple as with a report.
What you need to do is to create a pipelined function, that returns your date and count data. This pipelined function can be the base of a pseudo-table, which can be used in a select. For the pipelined function you need to define types for one row and a table to define the return-type for your function:
create or replace type calendar_row as object (date_time date, description varchar2(250));
create type calendar_table as table of calendar_row;
Then you can create the package with the function:
================================================
create or replace package dyn_calendar is
procedure set_query(i_query in varchar2);
function view_source return calendar_table pipelined;
end;
create or replace package body dyn_calendar is
v_query varchar2(100) := null;
procedure set_query(i_query in varchar2) is
begin
v_query := i_query;
end;
function view_source return calendar_table pipelined is
TYPE cursor IS REF CURSOR;
c_cal cursor;
v_date_time date := null;
v_description varchar2(100) := null;
r_cal calendar_row;
begin
open c_cal for v_query;
fetch c_cal into v_date_time, v_description;
loop
exit when c_cal%notfound;
r_cal := calendar_row(v_date_time, v_description);
pipe row(r_cal);
fetch c_cal into v_date_time, v_description;
end loop;
return;
end;
end;
================================================
Now you can set query in a PL/SL region before the calendar:
dyn_calendar.set_query(SELECT count(*), ' || :P8_SOURCE_DATE || ' FROM ' || :P8_SOURCE_TABLE || ' GROUP BY ' || :P8_SOURCE_DATE);
and you can base your calendar on the query:
select * from table(dyn_calendar(view_source))
Good luck,
Dik

FLEXFIELD DEFAULT SQL STATEMENT

Hello all.
I created a flexfield on the PO Lines with a default type of sql statement. The statement
uses the po_lines item id, however when accessing the PO Summary form the default statement
seems to be firing prior the po line block is accessed and causing the sql statement to raise
some exception. Is there a way around this?
thanks and more power.

My question is the 300 queries can be simplified as a simple SQL like
Select MyName, count(MyID) from myTable
where myName = 'Name1'
group by MyName
Select MyName, count(MyID) from myTable
where myName = 'Name2'
group by MyName
Select MyName, count(MyID) from myTable
where myName = 'Name3'
group by MyName
can be some one use like following
Select MyName, count(MyID) from myTable
group by MyName
or save as a stored procedure which the web server or web page only hit database server once instead of 300 times.
I would like to know does ColdFusion is smart enough to know the SQL are similar and only run SQL once against dabase server.
In my opinion, query-of-a-query is a smart enough solution to the problem. In the following example, ColdFusion visits the database just once!
<cfquery name="mainQuery" datasource="myDSN">
select MyName, count(MyID) from myTable
group by MyName
</cfquery>
<cfquery dbType="query" name="subQuery1">
select *
from myQuery
where myName = 'Name1'
</cfquery>
<cfquery dbType="query" name="subQuery2">
select *
from myQuery
where myName = 'Name2'
</cfquery>
<cfquery dbType="query" name="subQuery300">
select *
from myQuery
where myName = 'Name300'
</cfquery>

How can i use one SQL statement to solve problem?

How can i use one SQL statement to solve the question below?
For a Table named A, there is a column named F(char type).
Now select all the records where F like '%00' and update their F value to '%01'
Just one SQL statement.Do not use PL/SQL block.
How to do that?
Thanks.

What is the data volume for this table?
Do you expect lots of rows to have '%00' as their value?
Following two statements come to mind. Other experts would be able to provide better alternatives:
If you have index on SUBSTR(f, 2):
UPDATE A
SET    f = SUBSTR(f,
                  1,
                  length(f) - 2) || '01'
WHERE substr(f,
              -2) = '00';If most of the rows have pattern '%00':
UPDATE A
SET    f = SUBSTR(f,
                  1,
                  length(f) - 2) ||
           DECODE(SUBSTR(f,
                         -2),
                  '00',
                  '01',
                  SUBSTR(f,
                         -2));

How do I use SQL statements to perform calculations with form fields????

Please help!!! I don't know how to use a SQL statement within my APEX form......
My form is below. The user will enter the values in the form. Click on Submit. Then we need to run a SQL select statement with those values.
Our form looks like this:
Start_Date ____________
Per_Period ____________
Period ____________
[Submit Button]
The user will enter these 3 values in the form.
This is an example of an user providing the values:
Start_Date 03/14/08_______
Per_Period $200.00________
Period 4____________
[Submit Button]
Then they will click the Submit Button.
The SQL statement (BELOW) returns output based on the users selections:
START_DATE PER_PERIOD PERIOD
14-MAR-2008 00:00 200 Week 1 of 4
21-MAR-2008 00:00 200 Week 2 of 4
28-MAR-2008 00:00 200 Week 3 of 4
04-APR-2008 00:00 200 Week 4 of 4
Total 800
This is the full text of the SQL that makes the output above:
with criteria as (select to_date('03/14/08', 'mm/dd/rr') as start_date,
4 as periods,
'Week' as period,
200 per_period from dual),
periods as (select 'Week' period, 7 days, 0 months from dual
union all select 'BiWeek', 14, 0 from dual
union all select 'Month', 0, 1 from dual
union all select 'ByMonth', 0, 2 from dual
union all select 'Quarter', 0, 3 from dual
union all select 'Year', 0 , 12 from dual
t1 as (
select add_months(start_date,months*(level-1))+days*(level-1) start_date,
per_period,
c.period||' '||level||' of '||c.periods period
from criteria c join periods p on c.period = p.period
connect by level <= periods)
select case grouping(start_date)
when 1 then 'Total'
else to_char(start_date)
end start_date,
sum(per_period) per_period,
period
from t1
group by rollup ((start_date, period))

HOW TO: Post a SQL statement tuning request - template posting

This post is not a question, but similar to Rob van Wijk's "When your query takes too long ..." post should help to improve the quality of the requests for SQL statement tuning here on OTN.
On the OTN forum very often tuning requests about single SQL statements are posted, but the information provided is rather limited, and therefore it's not that simple to provide a meaningful advice. Instead of writing the same requests for additional information over and over again I thought I put together a post that describes how a "useful" post for such a request should look like and what information it should cover.
I've also prepared very detailed step-by-step instructions how to obtain that information on my blog, which can be used to easily gather the required information. It also covers again the details how to post the information properly here, in particular how to use the \ tag to preserve formatting and get a fixed font output:
http://oracle-randolf.blogspot.com/2009/02/basic-sql-statement-performance.html
So again: This post here describes how a "useful" post should look like and what information it ideally covers. The blog post explains in detail how to obtain that information.
In the future, rather than requesting the same additional information and explaining how to obtain it, I'll simply refer to this HOW TO post and the corresponding blog post which describes in detail how to get that information.
*Very important:*
Use the \ tag to enclose any output that should have its formatting preserved as shown below.
So if you want to use fixed font formatting that preserves the spaces etc., do the following:
\   This preserves formatting
\And it will look like this:
   This preserves formatting
   . . .Your post should cover the following information:
1. The SQL and a short description of its purpose
2. The version of your database with 4-digits (e.g. 10.2.0.4)
3. Optimizer related parameters
4. The TIMING and AUTOTRACE output
5. The EXPLAIN PLAN output
6. The TKPROF output snippet that corresponds to your statement
7. If you're on 10g or later, the DBMS_XPLAN.DISPLAY_CURSOR output
The above mentioned blog post describes in detail how to obtain that information.
Your post should have a meaningful subject, e.g. "SQL statement tuning request", and the message body should look similar to the following:

The following SQL statement has been identified to perform poorly. It currently takes up to 10 seconds to execute, but it's supposed to take a second at most.
This is the statement:

I'm sure that if you follow these instructions and obtain the information described, post them using a proper formatting (don't forget about the \ tag) you'll receive meaningful advice very soon.
So, just to make sure you didn't miss this point:Use proper formatting!
If you think I missed something important in this sample post let me know so that I can improve it.

PS: Just noticed that it actually sometimes doesn't show the proper formatting although the code tags are there. Changing to the \ tag helped in this case, but it seems to be odd.

SQl statement cause extreme Portal log growth

Our Portal server log file is growing very fast (30 - 50 Mb per minute). When examining the log file we see that the log file does contain only the error messages:

This message occurs more than 500 times per log file. It has something to do with Knowledge management, but we cannot find anything that triggers this sql statement.
Any ideas?
Noel Hendrikx & Pascal Rijnart

SAP tells us in reaction to our customer message:
"The table's definition is correct. What has to be changed is the
computed type for field NAMESPACE and the generated file for the table.
As I wrote before, if you make any change in the field NAMESPACE the
new computation is started (so change the description which has no
effect on the table's version on the database). Make the change and
save the table in the SapNetWeaver Developer Studio. You will then
see that the field's JDBC-type changes to VARCHAR.
Choose 'Create archive' for Dictionary Project the table belongs to
and deploy the sda on the database. Both can be done in the studio."
Can anyone tell us what to do now?

Any Idea?
Regards,

Statement statement = connection.createStatement();
//createing a statement object
String query= "INSERT INTO table......"
output.append("\nSending query:" + connection.nativeSQL(query));
int result = statement.executeUpdate(query);//updates database wit record
if (result==1)
output.append("\ninsertation successfull");
JOptionPane.showMessageDialog(null,"Insertation successfull ",
JOptionPane.INFORMATION_MESSAGE);
else
output.append("\ninsertation unsuccessfull");
JOptionPane.showMessageDialog(null,"Insertation unsuccessfull",
JOptionPane.WARNING_MESSAGE);
statement.close();
have left out the trys and catches and some other bits and pieces that i dont think ud need its the bare bones but it might help or at least give u an idea. have used this code before to do something similar.

Can we use if/else in sql statement?

Hi,
Is it possible to write a sql statement like the one below (not plsql)?
if (select 'True' from dual) = 'True' -- 1
then
select 'True' from dual; -- 2
else
select 'False' from dual; -- 3
endBasically, I want to execute either sql 2 or 3 based on the result of sql 1. I'm not sure if this is possible using only sql and not having to write a stored proc.
What are the different ways I can implement this?
Thanks for the help.

The case syntax is a bit funny though as there's not a single condition evaluation (like a DECODE or case structs from some other languages).
This is what I would expect a typical case struct to look like - evaluating a single condition:
case <condition>
when <value-1> then return <result-1>
when <value-n> then return <result-n>
else
return <return-z>
end

Can someone help me correct this sql statement in a jsp page?

ive been getting the java.sql.SQLException: Incorrect syntax error for one of my sql nested statements. i cant seem to find similar egs online, so reckon if anyone here could help, really appreciate it.
as im putting the nested sql in jsp page, it has to be with lots of " " n crap. very confusing if there are nested.
heres the sql statement without those "" that i want to use:
select top 5 * from(
select top+"'"+offset+"'"+" * from prod where cat=" +"'" cat "'"+"
)order by prodID desc
when i put this in my jsp pg, i had to add "" to become:
String sql = "select top 5 * from("+"select top"+"'"+offset+"'"+" * from prod where cat=" +"'" +cat+ "'"+")order by prodID desc";cat=" +"'" cat "'"+")order by prodID desc";
all those "" are confusing me to no end, so i cant figure out what should be the correct syntax. the error says the syntax error is near the offset.

If offset is, say, 10, and cat is, say, "new", then it looks like you're going to produce the SQL:
select top 5 * from(
select top '10' * from prod where cat='new'
)order by prodID descThat looks exactly like incorrect syntax to me... top almost certainly can't handle a string literal as its operand... you almost certainly would want "top 10" instead of "top '10'"...
If you use PreparedStatement, you don't have to remember what you quote and what you don't and you can have your SQL in a single static final string to boot...

Help with SQL statement in a coldfusion application

I created 2 drop down list boxes one that contains the months
and the second that contains the year. Right now my sql statement
is Select * from job where releaseDate=#imageDate#. Now this was
written in 2006 and I didn't know they were going to continue to
use the tool in 2007. So now I need a sql statement that if a user
selects Jan 2007 that all of jan 2007 will display. The format for
the datetime field in the database is Jan 2 2007 hh:mm:ss the first
box is named imageDate and the second is called StatusDate

Take a look at the T-SQL datepart function.
