Store Query Output or Cache Query

My search query returns almost about 5000 records or more at
a time out of 7million records. and I am outputing about 35 records
at a time on a page. The problem is when the user pages to the next
page, I hit the DB again and again through the paging process of
the user.
The Cache attribute of <cfquery> does not work when you
are using <cfqueryparam> methods in the Components which we
are using.
How can I Store all the outputs of the Query returned into a
var and cycle through it instead of hitting the DB every time or is
there another method of caching this returned query output?
Please give example.

Thanks, that did the trick, another problem that came out of
this is Internet Explorer. When Users page to lets say page #6 and
then use the back button to come back, when it reaches the page
one,the Query executes again. This only happens with internet
explorer. I have tried caching the page but still same problem
persists. I have changed the form method to "get" and it is still
problematic.

Hello,
-T:
Specifies that the bcp utility connects to SQL Server with a trusted connection using integrated security. The security credentials of the network user,
login_id, and password are not required. If
–T is not specified, you need to specify
–U and –P to successfully log in.
-U:
Specifies the login ID used to connect to SQL Server.
Note: When the bcp utility is connecting to SQL Server with a trusted connection using integrated security, use the
-T option (trusted connection) instead of the
user name and password combination
I would suggest you take a look at the following article:
bcp Utility: http://technet.microsoft.com/en-us/library/ms162802.aspx

cache-query-results question

I have another post for general descriptor tag information but I do have a specific question. In a project I am looking at I see:
<cache-usage> check cache by primary key </cache-usage>
<cache-query-results>false</cache-query-results>
<maintain-cache>true</maintain-cache>
I'm not sure how to interpret this. Does this mean that a cache is in place or not? cache-query-rests is set to false which implies no caching, yet the other parameters imply a cache is in place. What overrides here?
Thanks

The XML maps directly to the API so the JavaDocs and related documentation are the best tools:
cache-usage: query.setCacheUsage(int)
This option indicates how the object cache should be used when processing the query. This is how in-memory query is configured as well as support for cache-hits on ReadObjectQuery.
cache-query-result: query.setShouldCacheQueryResults(boolean)
This option allows you to indicate that the results returned from the query execution should be held. When the query is executed again these results will be returned without going to the database or searching the object cache. This is just caching the results locally within the query.
maintain-cache: query.maintainCache() or query.dontMaintainCache()
This setting determines if the results returned from the query should be cached in the shared object cache. It is on by default and turning this off is very rare. Occasionally done to compare the cache version with the database verision when handling an optimistic locking failure.

You're in the wrong forum (this one is for issues with the SQL Developer tool). You were in the right one where you posted first, but don't reuse unrelated threads as you did.

Query Output to download in flat file through APD or other means?

Hello Experts,
I am currently on BW3.5 system and have requirement to load query output in flat file in .csv format. I checked the option of APD but looks like we cant directly load the query output in flat file like in APD (BW 3.5 system) .
One way i can think of it...load the query output in transactional ODS and built an infospoke on it to write into flat file.
Please advice if there are any better methods to store the query output in flat files.
Thanks!

* in Query Output

I am getting asterisk ( * ) in the output of my query. This is in the columns where i am displaying key figures. This happens when i run it in either designer or analyzer.
I am displaying net weight and doing the appropriate conversions.
The only way to prevent this asterisk from appearing is to restart the Bex analyzer.
Since the asterisk disappears once i restart, i concluded that it is not a problem with my conversions.
I also checked the values being displayed and they reconciled with values in the InfoProvider.
This is not a problem with my conversions.
What else could be causing this problem?
Is it a system bug?
How do i prevent this from happening?
Thanks in Advance.

Hi Anish,
Yes.. it is a system problem ... Its due to Cache overflow..

How to store data from a complex query and only fresh hourly or daily?

We have a report which runs quite slow (1-2 minutes) because the query is quite complicate, so we would like to run this query daily only and store in a table so for those procedures that need to use this complex query as a subquery, can just join to this table directly to get results.
However, I am not sure what kind of object I should use to store data for this complex query. Is data in global temp table only persist within transaction? I need something that can persist the data and be access by procedures.
Any suggestions are welcome,
Cheers

Thank you for your reply. I looked at the materialized view earlier on, but have some difficulties to use it. So I have some questions here:
1.The complex query is not a sum or aggregate functions, it just need to get data from different tables based on different conditions, in this case is it still appropriate to use meterialized view?
2.If it is, I created one, but how to use it in my procedure? From the articles I read, it seems I can't just query from this view directly. So do I need to keep the complex query in my procedure and how the procedure will use the meterialized view instead?
3. I also put the complex query in a normal view, then create a materialized view for this normal view (I expect the data from the complex query will be cache here), then in the procedure I just select * from my_NormalView, but it takes the same time to run even when I set the QUERY_REWRITE_ENABLED to true in the alter session. So I am not sure what else I need to do to make sure the procedure use the materialized view instead of the normal view. Can I query from the Materialized View directly?
Below in the code I copied from one of the article to create the materialized view based on my normal view:
CREATE MATERIALIZED VIEW HK3ControlDB.MW_RIRating
PCTFREE 5 PCTUSED 60
TABLESPACE "USERS"
STORAGE (INITIAL 50K NEXT 50K)
USING INDEX STORAGE (INITIAL 25K NEXT 25K)
REFRESH START WITH ROUND(SYSDATE + 1) + 11/24
NEXT NEXT_DAY(TRUNC(SYSDATE), 'MONDAY') + 15/24
enable query rewrite
AS SELECT * FROM HK3ControlDB.VW_RIRating;
Cheers

Storing query output data in a DSO

Hi Expert,
Can you please tell me how to store a query output in a DSO?
Thanks in advance for your help!

Hi,
You can store the Query output data into DSO through the APD process.
Analysis Process Designer Uses:
In SAP BW, data from various databases from systems available in the company are collected, consolidated, managed and prepared for evaluation purposes. There is often further, valuable potential in this data.

Query output in APD shows zero values

Hi ,
I am using query output in APD . The query has got some calculated key figures for which the output result of the query in APD shows zero .Is there any way to resolve this .
regards,

Hi,
You need to store the source key figure value in a separate variable lets say v1 then **** the new variable v1 value to circular right, then remove the gaps, and then again shift V1 right by deleting trailing spaces and then finally copy the value in V1 to source or target key figure.
Hope this helps.

Need help to format the output of the query.

First of all i would like to say I m newbi in oracle query
and of course thanks to read the thread.
I have a problem formatting a query output.
Actually the query is like the following :
select a1
,b1
,c1
from table
where id.table=1
UNION
select a2
,b2
,c2
from table2
where id.table2=1
order by 1;
exit;
my actual output
a1 b1 c1
a2 b2 c2
a1 b1 c1
a2 b2 c2
my desired output
a1 b1 c1
a2 b2 c2
a1 b1 c1
a2 b2 c2
So what i need is an empy row between the groups of results
and to shift the union query.
thanks in advance

Can you store the resultSet from a query into a vector?

I am totally frustrated. How the heck does one store the results of a query (resultSet) in a vector so that I can get the vector from my jsp page to display in a table.? searchRS is my resultSet from stmt.executeQuery().
public Vector storeResultSet ()throws SQLException
int dataType;
Vector rows = new Vector();
System.out.println("INSIDE SEARCHQUERY VALUE OF searchRS: " + searchRS);
// Get the ResultSetMetaData. This will be used for the column headings
ResultSetMetaData rsmd = searchRS.getMetaData();
// Get the number of columns in the result set
int numCols = rsmd.getColumnCount ();
columnNames = new String[numCols];
System.out.println("inside of store results and column count of rsmd is: " + numCols);
boolean more = searchRS.next();
while (more)
Vector testData = new Vector();
for(int i=0;i<numCols;i++)
Object value = searchRS.getObject(i);
rows.add(value);
System.out.println("VALUE of testData vector is: " + rows);
more = searchRS.next ();
rows.add(testData);
System.out.println("This is the populated vector in storeSearchResults " + rows);
return rows;

Issue In query output

Hello Gurus,
I am having an issue with query output.Please find below the details of it
Unsold claims: Total---> 200
Dispatch: Total--->118,086
Unsold claims/dispatch--->0.001694
This should be the output but its coming --.0033120 because itu2019s dividing with max value in dispatch which is 60,386.
Reason: The aggregation property of Dispatch is max value. I am not supposed to do any changes in Modeling. So can we do any thing at reporting level to get the desired output?
Desired output---->0.001694
Output coming---->.0033120
Please help me in getting the desired output at query level.
