Query database daily automatically

I have a database (MSAccess) that users can access and add
records. Individual pages are in ASP and everything is working
well.
What I want to do now is to query the database once a day,
automatically, to look for changes based on a particular date
field. I haven't a clue if it is even possible to automatically
open and run an ASP page unattended. Not even sure if I'm asking
the right question in the correct forum (sorry if I'm not!)
Anyone help? Thanks in advance.

Maybe it's just me, but I think you need to think this
through a bit more.
Why do you need this query to "run an asp page unattended"?
It's not going
to show the data to you until you go and visit the page
anyway, right? So
why have it "run unattended" instead of just having the page
display the
changes you're looking for?

Standby databse for a query database

Hi,
Can I use a standby database to make a query database.
My idee is :
create a standby database on production,
daily open this one in read/only,
and nightly recover standby database.
Is it available ?
thanks in advance for your help.
gnom92.

There is no rule of thumb. It really depends on how much REDO is generated by the primary database. If the primary is CPU-bound processing transactions 24 hours a day, it will take a lot longer to recover the standby than it would if the primary has a moderate transaction volume.
If you have tested your recovery plan recently, you can probably make a pretty good estimate, since that is basically what the standby is doing. If it takes you an hour to apply a day's worth of archive logs to recover your system, it will take an hour to recover your standby database (assuming identical hardware & software configuration).

Error: 1013020 Cannot clear data for database [Daily] while other users are

I'm trying to clear a (BSO, v 11.1.2.1) database, and it's failing with the following message:
Error: 1013020 Cannot clear data for database [Daily] while other users are connected.
There are no other users connected first of all. Second of all, I've never had a database fail to clear just because other users were connected. Has anyone seen this before?

WHen ever u start essbase application ..there is services starts in task manager called "ESSSvr" . The number get increased when keep opening as number of application you open ..So what i say is when u see no users in sesssion and no batch runs ahead , u can stop the Application in EAS and automatically it will log off all the users from that respective application ..And then start again the application and u can perform ur task
this usually happnes when some one is connected with excel addin or Same EAS open by another user remotely..thats what i have seen in my exp's

Query for daily sales by warehouse

Hi
I need a query for   Daily sales by warehouse. I am only new to this and struggling with generating.
ideally it will look like the below.     With no selection criteria as I would like to schedule the report to email out at the end of each day.
Warehouse      Revenue      GP          GP%
NSW               $xxxx             $xxx       35%
Would someone mind helping
thanks

thankyou ,   But i have multiple warehouse and i dont want to use a selection criteria.
to expand on the original example
Warehouse      Revenue      GP          GP%
NSW                 $xxxx             $xxx           35%
QLD                  $xxx               $xx            32%
VIC                  $xxx               $xx            32%
Also the results should only show figures for the day the query is executed
Any help is appreciated.
Similar layout to this,except using query and whs code.    the below is generated using sales analysis and customer group.

Orcl:query-database gives error when using to_char function in select stmt

Use Case : We get a csv file ("bank_import_<MMDDYYYYY>.csv") from the bank containing the transactions occured for the month.

XPath 2.0 specifications define a fn:format-date function but Oracle has not included yet in its XQuery implementation.
Easiest way to go is A_Non's solution, but if you need to format at multiple places in the query, you can declare a local XQuery function.
For example, to format to "DD/MM/YYYY" from the canonical xs:date format "YYYY-MM-DD" :
{code}
declare function local:format-date($d as xs:date) as xs:string
let $s := xs:string($d)
return concat(
substring($s, 10, 2), "/",
substring($s, 7, 2), "/",
substring($s, 2, 4)
{code}
and an example of use :
{code}
SQL> CREATE TABLE test_xqdate AS SELECT sysdate dt FROM dual;

SQL> SELECT *
2 FROM XMLTable(
3 'declare function local:format-date($d as xs:date) as xs:string

Query Syntax Bug in orcl:query-database function

Hi,
I have a 'Transform' process activity, I have a Description and I intend to get the corresponding Id on the basis of the "text Description".
e.g.
Input: "Jack"
table: EMP [i.e. Employee Table]
Expected Query: SELECT EMP_ID FROM EMP WHERE EMP_NAME = "Jack"
<SNIP>
<ns0:empId>
<xsl:value-of select="orcl:query-database('SELECT EMP_ID FROM EMP WHERE EMP_NAME="Jack"', false(), false(), 'jdbc:oracle:thin:soaadmin/soaadmin@localhost:1521:XE')"/>
</ns0:empId>
</SNIP>
Presently Resulting as:
oracle.xml.sql.OracleXMLSQLException: ORA-00904: "Jack": invalid identifier
Details:
It seems that it is not accepting quotes in the query.
- I tried escaping quote however it did not work.
- I tried giving " or amp;quot; or " - nothing worked.
Please Suggest me something on this.
regards
Joy

How about:
<ns0:empId>
<xsl:value-of select="orcl:query-database('SELECT EMP_ID FROM EMP WHERE EMP_NAME=&apos;Jack&apos;', false(), false(), 'jdbc:oracle:thin:soaadmin/soaadmin@localhost:1521:XE')"/>
</ns0:empId>

Problem in using query-database() function in Transformation

Hi All,
I am using JDev and SOA 10.1.3.4.
I have an async process.
In that I am doing a transformation in which source is InputVariable and target is result.
In Transformation I am using query-database function to fetch a record from DB and am assigning that to result.
*<xsl:value-of select='orcl:query-database(concat("select ename from emp where empid=",/ns1:DBXSLProcessRequest/ns1:input),false(),false(),"jdbc:oracle:thin:scott/tiger@localhost:1521:abcd")'/>*
I am not getting any error but query-database is not returning any thing I maen it is returning null.
If i run that query in SQL prompt it is returning the empname.
Please help me out.
Regards
PavanKumar.M

Hi Pavan
I tried following in BPEL transform actvity's XSL file, and it works fine and returns the sysdate for me.
<xsl:value-of select='orcl:query-database("select sysdate from dual",false,false,"jdbc/myDS")'/>
Can you try above in new XSL file of Transform activity and let me know its gives you the result? if it works you can start making changes according to your requirement.
steps to follow:
1.create connection pool in EM, and make sure its working fine by using test on connection pool.
2.create Datasource and point to above created connection pool. and restart the oc4j_soa
3.rename the xsl file name of transform activity in BPEL and use above query-database function.some times xsl files are cached even if you make changes it will not take effect so for testing if you rename it will be good.
Thanks

Use of sql group function in orcl:query-database - urgent

All,
Version: 10.1.3.4
Two requirements for me:
1. I want to use sum function in orcl:query-database. How to use it?
For ex: I tried the following
<xsl:value-of select='orcl:query-database("select sum(salary) from emp",false(),false(),"jdbc/DB1")'/>
I got the following error
oracle.xml.sql.OracleXMLSQLException: Character ')' is not allowed in an XML tag name.
When I tried without sum function, it works fine
2. I used the same table, but without the sum function as below
<xsl:value-of select='orcl:query-database("select salary from emp",false(),false(),"jdbc/DB1")'/>
This time, it returns the first employees salary!! I dont understand this logic. I expected either the query returns all the rows else it throws error, but none of them were true!
Can anyone pls explain what is the behavior? I want your reply for both the queries!
Currently I'm in a project where I'm working in the similar scenario, so please guru's let me know ASAP.
Thanks,
Sen

Hi Sen,
Create a normal variable variable in XSLT.
Then use that variable.
I mean variable name='Var_1' select='Your Query'
Now use Var_1/yourcollection/...
I am giving some example
<xsl:variable name="Stopdetails" select="/ns0:MyEBM/ns0:DataArea/ns0:MyEBO/ns0:Stops/ns0:Stop[ns0:StopID=$TempStopId]"/>
<xsl:variable name="AccStopTypeVar">
<xsl:value-of select="$Stopdetails/ns0:StopType"/>
</xsl:variable>If you want you can loop on the created variable.
You can do these in XSL.
But DB calls those things ...it would be better , if u take them out. Spme debugging problems are there with XSL.

Query Database - Write to Database

I am querying a SQL DB which has 10 results in total with 15 fields each. The run book will filter out 2 eventually based on some rules.
Once all the activities are complete as per the runbook, I want to write back to the database as 'Complete' under Field called Status
The write works, however it creates a new item completely. I want to update the existing request
Regards, Vik Singh "If this thread answered your question, please click on "Mark as Answer"

So if I understand correctly you are querying a database and based on the response you do some activities and then you want to update the records you queried in order to indicate that the activities have been completed?
If you just want to update the existing records then I would probably just do an Update query based on the primary-key of the record you queried using the "Query Database" activity instead of the "Write to Database" (which always writes
a new record).
Something like: Update [Table Name] set Status = 'Completed' where PrimaryKey = 'xxx'
You will probably need to cut up the Query Result from your first query first in order to get the Primary Key.
Usually I do this by reading Published Data "Full Line as String Seperated by ;" with a PowerShell Script (Run .NET Activity).
For example:
$Query = <Full Line as String > //Published Data from the Query activity
$All_Records = $Query.Split(";") //this creates an array where every record is a column from the query result
$PrimaryKey = $All_Records[0] (if the primarykey is found in the first record of the array of course)
Then use that $PrimaryKey value in your new query.

Problem in using oraext:query-database() command in xslt

Hi,
I am querying a function through the query-database() command in a certain xslt within a BPEL Process as below:
<xsl:variable name="Corporation">

</xsl:variable>
But, after deploying the BPEL Process and while running it, I am getting error at run-time.

Hi Anshul,
Thanks for replying.
The query upon executing in SQL Plus returns proper value. The result is either a concatenated string or 'NO_DATA'.
Please note that: $getCustAccID --> x-path expression and $Corporation --> hardcoded value - 'CORPORATION'.
I have tried formatting the string of the query in various ways, but no luck.. In all cases the error is same.
Waiting for your reply.
Thanks in advance..

kindly someone help me to resolve this issue

Hi ervan,
Use the jdbc/datasource instead of eis/DB/EBS.
oraext:query-database('select no,name,mark from vivek_test',false(),false(),' jdbc/datasourceName ')
See if this helps

Orcl:query-database ERROR

I am getting following error when I use orcl:query-database() function. JNDI name is correct and working for DB adapters. I dont knwo whats wrong with this..
<subLanguageExecutionFault xmlns="http://schemas.oracle.com/bpel/extension"><part name="code"><code>XPathExecutionError</code>
</part><part name="summary"><summary>XPath expression failed to execute.
Error while processing xpath expression, the expression is "orcl:query-database('select testan_s.nextval from dual',false(),false(),'eis/DB/TEST)", the reason is message can't be null.
Please verify the xpath query.
</summary>
</part></subLanguageExecutionFault>

Using JNDI name gives this freak error. If you use jdbc url string then it works in the last parameter.
It is really sad that these kind of simple functions are not working even in 10.1.3.3 which makes it very difficult to design the process in a simple way.
When will these will be fixed? is there any workaround? I need to use this in XSL transformations. any one has a clue?

Transformation not working on result from oraext:query-database() functio

Step 1: Create a project in Jdeveloper (File->New->Project->SOA Project)
Step 2: Select synchronous process
Step 3: Take the default schema for input and output
Step 4: create a schema to hold multiple simple type string values.
Step 5: Import that xsd file in the project wsdl file.
Step6: Create a another variable (var1) referring the above element type (result)
Step7: Drop an assign activity from component palette to the process between Receive and Replay activity
Step 8: In the from section use the function oraext:query-database("select ename from emp",true(),true(),'jdbc/EBS_database').in the to section select the var1 variable.
Step9: Drop another assign activity from component palette to the process before Replay activity and after the first assign activity
Step 10: In from section select the first ename using xpath from var variable and assign to the output variable.
Error: The value is not coming to the output from source(var) variable using xpath or transformation.

See the audit trail on EM and verify why it is not working.
