Pure SQL query

I am trying to execute a pure SQL statement. But my DB adapter is not fetching any output.
select installation_type from oid_staa_desc_mapping where Acode in ('A','B')
I am not sure why this doesn't work.

Here User StartDate: 22/09/2010 , EndDate: 27/09/2010
SQL Query Check ,
Condtion 1 : Those dates are avilable in Datebase???
Result: Yes
Because, Sample Poll date is 23/09/2010 to 26/09/2010, here Start Date is Not Exists, But End Date Exists.
So dnt allow Save Operation....
Now User Again given follwing details and click Submit,

How to build dynamic query strings in the query using DB adapter 'Pure SQL'

Dear Forum,
I am building an application which will access DB to fetch some result set. The query involves retrieving data from multiple tables(nearly 10 tables). So I have created a DB adapter using 'execute pure sql' option. With this query works fine, but my inputs parameters will vary. So I need to make my query dynamic to append the query strings at runtime depending on the inputs.
For example I have 3 input variables - input1,input2 and input3 (in my request xsd) which are used in the pure sql query. Now if I get a 4th input parameter input4 in the request, I need to append this to query string as 'AND input4=[some value]' at runtime. Otherwise my query should have only 3 parameters. Please suggest how this can be achieved.
Regards,
Satya.

This is a strange requirement, depending on the columns you have and what are optional in them, one way is to have separate operations and each opeartion will have different inputs and for each operation , a different DB Adapter is called. But this way, it results in more number of operations for the service as well as more number of references in the composite. Even if you pass the column inputs to the SQL procedure, it will result in a large number of if-else cases..
Thanks,

Dynamic SQL Query to Find Special Characters in Table columns

Hi,
I am new to OTN FORUMS.
I am trying to find the columnsi of a table which have special characters in them.
I am planning on using this query
select ' select INSTR('||column_name||', chr(0))
from '||table_name||'where INSTR('||column_name||', chr(0)) >0' from user_tab_columns
where table_name='Account'
and spool the output to run as a script.
Is this the right way or do u suggest any modifications to the query?
Thanks in advance.

Hi,
I think your basic approach is right. Since you can't hard-code the table- or column names into the query, you'll need dynamic SQL.
Instead SQL-from-SQL (that is, writing a pure SQL query, whose output is SQL code), you could do the whole job in PL/SQL, but I don't see any huge advantage either way.
When you say "Special characters", do you really mean "one given special character" (in this case, CHR(0))?
Will you ever want to search for multiple special characters at once?
What if table foo has a column bar, and in 1000 rows of foo, bar contains CHR (0). Do you want 1000 rows of output, each showing the exact position of the first CHR(0)? If the purpose is to look at theese rows later, shouldn't you include the primary key in the output? What if CHR(0) occurs 2 or more times in the same string?
If you'd rather have one row of output, that simply says that the column foo.bar sometimes contains a CHR(0), then you could do something like this:
SELECT 'foo', 'bar'
FROM dual
WHERE EXISTS (
 SELECT NULL
 FROM foo
 WHERE INSTR ( bar
 , CHR (0)
 ) > 0
 );

SQL- Query that return only one record

Hello,
is it possible to execute a pure SQL-Query which returns only one row although multiple rows are found.
It is no problem in PL/SQL, but I have no idea if the same is also possible in SQL.
thanks in advance

Why not? There are 4 records in this table, but only selected one.
SQL> with t

Crosstab query using pure SQL only

Hi all,
Found a lot of threads on crosstab, but none seems to address what I need. I need to perform crosstab query using pure SQL only & the number of columns are dynamic. From a query, I obtained the below table:
Name Date Amount
Alex 2005-06-10 1000
Alex 2005-06-20 1000
Alex 2005-07-10 1000
Alex 2005-07-20 1000
Alex 2005-08-10 1000
Alex 2005-08-20 1000
John 2005-06-10 2000
John 2005-06-20 2000
John 2005-07-10 2000
John 2005-07-20 2000
John 2005-08-10 2000
John 2005-08-20 2000
And I need to transform it into:
Name 06-2005 07-2005 08-2005
Alex 2000 2000 2000
John 4000 4000 4000
Reason for the columns being dynamic is because they'll be a limit on the date ranges to select the data from. I'd have a lower & upper bound date say June-2005 to August-2005, which explains how I got the data from the above table.
Please advise.
Thanks!

Hi,
I couldn't resist the intellectual challenge of a pure SQL solution for a pivot table with a dynamic number of columns. As Laurent pointed out, a SQL query can only have a fixed number of columns. You can fake a dynamic number of columns, though, by selecting a single column containing data at fixed positions.
 
 
If it were me, I'd use a PL/SQL solution, but if you must have a pure SQL solution, here is an admittedly gruesome one. It shows the sum of all EMP salaries per department over a date range defined by start and end date parameters (which I've hardcoded for simplicity). Perhaps some of the techniques demonstrated may help you in your situation.

Now, if we substitute '1981-03-01' with '1981-06-01', we see 7 columns instead of 4

30 | 0 | 2850 | 0 | 0 | 2850 | 0
40 | 0 | 0 | 0 | 0 | 0 | 0
 To understand the solution, start by running the innermost subquery by itself and then work your way outward.

How to create a Matrix table using this data in SQL Query Analyzer

Hello all,
I have a problem while I am trying to represent my Sql Table namely table1 in Matrix form
my table Format is
city1 city2 Distance--------------------------------------------------------
Mumbai Delhi 100
Delhi Banaras 50
Mumbai Rajasthan 70
Banaras haryana 40
Mumbai Mumbai 0
784 entries
there are 784 cities each having link to other
Now i want my output as
Mumbai Delhi Banaras haryana
Mumbai 0 100 -- --
Delhi 100 0 50 --
Banaras
haryana
respective distance from one city to other should be shown
final Matrix would be 784*784
I am using SQL Query Analyser for this
Please help me in this regard

I'm pretty much certain that you don't want to do this in pure SQL. So that means that you want to do it with a reporting tool. I'm not familiar with SQL Query Analyzer, but if it is in fact a reporting tool you'll want to consult its documentation looking for the terms "pivot" or perhaps "cross tab."

Help Required -- Can we use SQL Query to READ data from SAP MDM Tables

Hi All,
Please help.........
Can we use SQL Query to READ(No Creation/Updation/Deletion just Read) Data from SAP MDM tables directly, without using MDM Syndicator.
Or direct SQL access to SAP MDM tables is not possible. Only through MDM Syndicator can we export data.
Thanks in Advance
Regards

All the tables you create in Repository comes under A2i_CM_Tables in Database named as your repository name. So the tables names are fields of table A2i_CM_Tables. Now i tried it but cant make it.
Now, I dont think its possible to extract all fields in tables and there values using select query. May be pure sql guy can do that or not.
But there is no relation of data extraction and syndicator. Data is viewed in Data Manager. and you can also store data in a file from DM also.

It's curious that the WHERE clause includes "PROJECT_STATUS='6'", but there is no pivoted column for project_status='6', like there is for '1' through '5'. That's not necessarily a mistake, and it wouldn't raise an error in any case.
Instead of
where (PROJECT_STATUS='1' or PROJECT_STATUS='2' or PROJECT_STATUS='3' or PROJECT_STATUS='4' or PROJECT_STATUS='5' or PROJECT_STATUS='6')you could say
where PROJECT_STATUS IN ('1', '2', '3', '4', '5', '6')but that probably has nothing to do with your current problem.

I'm getting a "Failed to parse SQL query!" error when I try to run validation.Is that an Apex error message? Sorry, I don't know anything about Apex.
If you can't get a more specific error message from Apex, then try debugging this statement in SQL*Plus. When you get it fixed, then you can copy it back into Apex.
If this is a SQL problem, then you should be able to re-create the problem in pure SQL.
If you can't re-create the problem in pure SQL, then it's probably an Apex problem, and belongs in the Apex forum, not here.
I don't see anything obviously wrong with your code, but I can't tell if, for example, you spelled a column name wrong, or if something has the wrong data type
Is this enough info for some assistance? Any help would really be appreciated.It wiould be better if you posted a completE script that people could run to re-create the problem, and to test their ideas.
Whenever you have a problem, please post a little sample data (CREATE TABLE and INSERT statements, relevant columns only) from all tables involved.
Also post the results you want from that data, and an explanation of how you get those results from that data, with specific examples.
Always say which version of Oracle (and any other software, such as Apex) you're using.

Pure sql in DB adapter

Hi All,
Here is my scenario:
I wnat to take teh dat from the database tables and generate teh reports in BAM. Al;ready I have SQL queries to generate the report. I want to pool the db tables for every 2 mins and generate the report .
My question is :
Is there is any way to trigge teh pure SQL in DB adapter for every certain intervat of time? Please help me on this. also suggest me best approach..
Thanks
Venkat

Hi Venkat
1. Hope you are familiar with BAM Reports architecture and how it works. Its pretty straight forward.
2. First you create a DataSource to any external Database giving the db host, port, sid, username/password. This database contains like Tables, Views, etc etc.
3. You create a DataObject that References any component of this database like Table, View etc. So you have a SQL that joins multiple tables and fetches data. Simply Create a View for that SQL Query on database side like database View. Then create a BAM Data Object for that View. It shows all Columns from that View. Simply Rename them if you want or just leave as it is. Just run the View and it shows all the data records. Remember this is dynamic. There is no need to refresh or trigger. Say if the table had a new row, the View will just show that new row.
4. Now create a Report (Web or excel format) for the above Data Object. Report by default will show all the column from Data Object. Pick the columns you want to add to that Report.
Run the Report. Data in Report is 100% Dynamic. If backend tables had new rows or deleted rows, just run the Report and you will see the results.
Thanks

Pure SQL to partition date-time occurrences into non-overlapping windows?

i've a question that so far, i've never been able to solve via a pure SQL option.
it's hard to explain in words, but it's something like this:
given a set of date-time, i would like to partition the data into non-overlapping windows of 30 minutes each.
the data is supposed to be partitioned into windows of 30 minutes, meaning when the data is within 30 minutes of the first occurrence, only the first occurrence will be returned. in the next second after the 30th minute, the record will be considered as the start of a new window and is also returned. so those data that occurs within the window period are suppressed. the first occurrence is not necessarily occurring on the 00th minute, so the window start will never be constant.
run the below query to look at the dummy data.
SELECT 'A' AS ID
 , TRUNC(SYSDATE) + 7 / 24 + 1 *(ROWNUM - 1) / 1440 AS datetime
 FROM DUAL
CONNECT BY ROWNUM <= 50
UNION ALL
SELECT 'A' AS ID
 , TRUNC(SYSDATE) + 9 / 24 + 8 / 1440 + 1 *(ROWNUM - 1) / 1440 AS datetime
 FROM DUAL
CONNECT BY ROWNUM <= 35
UNION ALL
SELECT 'B' AS ID
 , TRUNC(SYSDATE) + 7 / 24 + 5 *(ROWNUM - 1) / 1440 AS datetime
 FROM DUAL
CONNECT BY ROWNUM <= 15this is supposed to be the output.
ID DATETIME
A 5/19/2010 07:00:00
A 5/19/2010 07:30:00
A 5/19/2010 09:08:00
A 5/19/2010 09:38:00
B 5/19/2010 07:00:00
B 5/19/2010 07:30:00
B 5/19/2010 08:00:00so far, i'm using a PL/SQL to pipe the records. but i would like to know if this is achievable via SQL or not.
i've tried looking at analytics, width_bucket, ntile and alll options i can think of, but i just can't solve this at all.

hey Bob,
your answer is most definitely correct and does what i want. i've verified it again my data set and it returns the results as required!
you've definitely proven me wrong. i was always under the impression that this wasn't possible. thanks!
just a small note:
i need the windows to be binned by seconds, so have changed the numtodsinterval to raw numbers.

I was developing a DB Adapter to select data from Shipping tables. I did it by polling as well as with Custom SQL. While using the custom SQL I got the following error in my domain.log
(my query that I wrote) failes, Caused by java.sql.SQLException: Invalid column index.
The Pure SQL option is for border use cases only and provides simple yet minimal functionality. Possibly try the "Perform an operation on a table" option instead.
What is a border use case, how do I decide that. So BPEL support the custom sql option very loosely?
Thx

The thing is that XSLT often doesn't deliver the functionality required when it comes to times.
You suggest appening "Z" to the time but this means that the time is now in UTC time. What if the system from where the date is being converted is running in NZ using local time? Other systems that recieve the date (and correctly handle the time zone) will now have a time that is out by a number of hours.
You often can't ignore the time zone (drop the 'Z') as if you send the time to a system it has to either assume the time is local to it (which may not be the case... the other system coudl be in a different time zone) or assume the time is UTC (I think crossfire does this by default).
Typically can't just append a time zone (e.g. +11:00) either as many places have daylight savings so the value to appended is variable (you then need some way of determining what the value is... either Java Embedding or a Service).
As you mention it does depend on the use case but in many circumstances using Jaba Embedding, not as suggested above but with the appropriate Java.util.Calendar classes, is the best way to handle date and time in BPEL. Even still you need to ascertain the format of times external to the system and ensure you parse them correctly.
ANd even if you do all this you can still run into problems. I've seen a real world example where two systems which both handled time zones correctly and had previously been working together for quite a while, satrted reporting different times. It turns out that only one of them had had the most recent Java Time Zone patches applied and there had been a change in the dates for daylight savings here (Australia). Be warned!

Iam trying to use pure sql option , i have pasted the modified query in this way below >

My Question is : The Pasted modified query is correct ???, and this type of below
nvl(pll.inspection_required_flag,'N'), -- if its Yes then ites 4 Way Matching
nvl(pll.receipt_required_flag,'N'), -- If Its Yes then its 3 Way Matching
decode(nvl(pll.inspection_required_flag,'N')
Is Allowed ???????

yeah , i was getting some error for that "--" but then i changed the query and now it does not have "---"
But i have a question here the xsd generated is like this ...
and query contains nvl(pll.cancel_flag,'N') which in xsd looks like below.
