SQL query returns few rows, but holds on with several Gbs of RAM memory used

If I perform the following query:
SELECT d.DocumentGUID, d.DocumentID
FROM ImportDataBase.dbo.Document d
LEFT OUTER JOIN ContentDataBase.dbo.Document d2 ON (d.DocumentGUID = d2.DocumentGUID)
WHERE ( d2.DocumentGUID IS NULL ) -- new document in the ImportDB
OR ( d2.DocumentGUID IS NOT NULL AND d.QueryContent <> d2.QueryContent ) -- modified document in the ImportDB
It returns around 1000 rows and takes about 3 minutes to complete
It also raises up the RAM memory used from 2GB to 9GBs.
This memory used will remain used untill I restart the server. I have no need to make use of that memory, I already copied the returned rows of that query into a note pad for example. And any other reason of SQL has to to keep that memory stored by
that query, I dont want it.
Is there a way to release that memory I really dont need my SQL server to keep, without having to restart the SQL server?
and without topping the max memory the sql server uses, since I need my SQL server to use as much as it needs in other tasks(I dont think it needs to hold on to the above query memory used)
Thank You very much.

A query can be resource intensive even if it returns a single row. Generally it is a good idea to set SQL Server MAX memory.
BOL: "Optimizing Server Performance Using Memory Configuration Options
The memory manager component of Microsoft SQL Server eliminates the need for manual management of the memory available to SQL Server. When SQL Server starts, it dynamically determines how much memory to allocate based on how much memory the operating system
and other applications are currently using. As the load on the computer and SQL Server changes, so does the memory allocated. For more information, see Memory Architecture.
The following server configuration options can be used to configure memory usage and affect server performance:
•min server memory
•max server memory
•max worker threads
•index create memory
•min memory per query
The min server memory server configuration option can be used to ensure that SQL Server does not release memory below the configured minimum server memory once that threshold is reached. This configuration option can be set to a specific value based on the
size and activity of your SQL Server. If you choose to set this value, set it to some reasonable value to ensure that the operating system does not request too much memory from SQL Server, which can affect SQL Server performance.
The max server memory server configuration option can be used to specify the maximum amount of memory SQL Server can allocate when it starts and while it runs. This configuration option can be set to a specific value if you know there are multiple applications
running at the same time as SQL Server and you want to guarantee that these applications have sufficient memory to run. If these other applications, such as Web or e-mail servers, request memory only as needed, then do not set the max server memory server
configuration option, because SQL Server releases memory to them as needed. However, applications often use whatever memory is available when they start and do not request more if needed. If an application that behaves in this manner runs on the same computer
at the same time as SQL Server, set the max server memory server configuration option to a value that guarantees that the memory required by the application is not allocated by SQL Server."

SQL Query returning no rows, please help!!

I have a table that contains user audits for a particular procedures alongwith the date stamp. Now, I want to list all the procedures not accessed by the users within the last 6 months. Or, all the procedures that have not been used/accessed during the last 6 months.
This is what I am trying but is not returning any rows:
SELECT DISTINCT proc_name,
TRUNC (entry_date)
FROM log_web
WHERE proc_name NOT IN (SELECT proc_name
FROM log_web
WHERE TRUNC (entry_date) > TRUNC (SYSDATE - 180))
ORDER BY 2 DESC
Please advise.
Thank you in advance.

Two possibilities leap to mind.
First, are you sure that there are any prodcedures not accessed in the last six months?
Second, is there a chance that there could be records with a null value in proc_name? If the sub-query used in a NOT IN predicate returns even one null value, the query will return no rows.
Does this return rows?
SELECT DISTINCT proc_name, TRUNC(entry_date)
FROM log_web
WHERE proc_name NOT IN (SELECT proc_name
                        FROM log_web
                        WHERE TRUNC (entry_date) > TRUNC (SYSDATE - 180) and
                              proc_name IS NOT NULL)
ORDER BY 2 DESCJohn

But the Output is not the expected one if we see for the PNUM = 000000, the records are displayed
3 times it should be only ones displayed and also for PNUM = 001645156. My Query is why is it displaying
more than once, is there anyway that we can display it only once. Can some please advice me where am making
wrong. Thanks in advance.

But both the output is wrong is there any way that i can get the result set as below, from the above query i can see duplicates
if the PNUM has more SEQ_NUM then it is again doing a cross join i think and hence the result set is coming wrong. The Below
is the expected output. Can some one help me out in getting this. Thanks in advance.

XML attributes makes my query return no rows

Hello everyone,
I've an odd problem.
I'm querying some XML, but the attributes in one of the tags make my query return no rows; if I remove the attributes, then the query works as expected.
The XML is below; it's the attributes in the Report tag that cause the issues:
<result errorCode="0">
     <return>
          <Report
               xsi:schemaLocation="Items_x0020_status_x0020_information http://******-****/ReportServer?%2FReports%2FContent%20Producer%20Reports%2FItems%20status%20information&rs%3AFormat=xml&rc%3ASchema=True"

Any help would be hugely appreciated!
Thank you very much in advance.

Query returns more row than expected

1. select * from view_name where col1 = 'value1' returns 12 rows
2. select * from (view script) where col1 = 'value1' returns 24 rows
i have a view called view_name. If i use view_name directly in the query, it returns 12 rows. But if i use the select script directly in from clause, it returns more rows. I am not able to find out why it is happening so. Any pointers will be helpful.

Are you saying that the SQL for view_name and view_script are identical? Can you post them?

Pl/sql block returning multiple rows

Hi,
I've created a plsql block which obtains an id from a name and then uses this id in another sql statement. The select statement to get the id works fine and the correct id is placed into the variable awardID.
when i try to use this variable in another select statement it returns multiple rows. but when i just use the id in the select statement it works fine.
select AwardID into awardID
from award_objtabA
where Name = awardName;
this returns the correct id '5999'
select Points into award_points
from award_objtabA
where AwardID = awardID;
this returns multiple rows
select Points into award_points
from award_objtabA
where AwardID = 5999;
this works fine
can anybody help with this confusing error?
Cheers

select AwardID
into awardID               <= the same column
from award_objtabA
where Name = awardName;
this returns the correct id '5999'
select Points
into award_points
from award_objtabA
where AwardID = awardID;    <= the same column
this returns multiple rows
to solve use different name not exactly the same as that of the column name
select AwardID
into vAwardID
from award_objtabA
where Name = awardName;
select Points
into award_points
from award_objtabA
where AwardID = vAwardID;as Alex and Kamal have suggested use different name for your variable.

Creating a directory via a jsp page sql query return

Is it possible to create a directory based on the results of a sql query?
i.e.
My sql query returns application number 1234 for a building application (BC for short).
Is it possible to create a directory /BC/1234
It is then proposed to use an iframe to look into the directory so users can place and access scanned documents which are captured during the approval process.
If so how?
An example would be great.
Jason

Sorry hope your still around I've been away for a while. We've created a samber share to the file server where the documents are stored and mounted it within the web file directory. It works ok if there is an existing directory but if there isn't we want it to be created when the page looks for the folder. I've done this with an asp page it basically did a directory exist test first then create folder if it didn't. The problem is can't find an example of how to do the directory exist test then directory create syntax so an example of both would be great

SQL query returns varchar - default value type!!!

On a field in my portal form there is a default value type of 'SQL query returns varchar', where can I put this sql to get a default value from a table?

Hi again
I have this code in 'additional pl/sql code' - '...before displaying the page'. But it comes up with an error when I run the form.
declare
prop_v varchar2(20);
group_v varchar2(3);
el1_v varchar2(3);
blk varchar2(10) := 'DEFAULT';
begin
prop_v := p_session.get_value_as_varchar2(p_block_name=>'DEFAULT', p_attribute_name => 'l_property_p');
group_v := p_session.get_value_as_varchar2(p_block_name=>'DEFAULT', p_attribute_name => 'l_group_p');
select element_code
into el1_v
from eh_risk_element_detail
where property_ref = prop_v
and group_code = group_v
and line_no = 1;
p_session.set_value(p_block_name => blk, p_attribute_name => 'L_ELEMENT1_P', p_value => el1_v);

[Excel] Running a SQL Query to delete rows

Hello Experts,
Background: I am attempting to use a dba of my companies time keeping system and implement it with Power BI tools. Given the file size restrictions within Power Bi itself I need to lower my file size by removing all time logs from
inactive employees.
I have a question regarding whether or not you can use a sql query to delete rows in excel. I have roughly 200,000+ rows in my excel spreadsheet. I am attempting to delete all rows where an employee equals inactive. I have attempted to
delete these rows by sorting them and doing a bulk delete and clear contents, but it seems to crash my excel every time. My thought process is that using a query that does a timed delete might put less of a burden on deleting the massive amount of data.
I would like to use this: DELETE * FROM [Table_(...)_Actual$] WHERE [Current] = "Inactive" (Will add more once I know it is possible to use sql queries in Excel.
Any information on whether or not this is possible would be appreciated.
Regards,
Link

Running SQL Query in Excel is possible, however, the delete query is not supported in Excel.
You are more restricted in deleting Excel data than data from a relational data source. In a relational database, "row" has no meaning or existence apart from "record"; in an Excel worksheet, this is not true. You can delete values
in fields (cells). Please see:http://support.microsoft.com/kb/257819/en-us
One workaround : Use update query to set the rows as null, then use select query.
e.g.
SQL = "update [sheet2$A1:B5] set name=null,age=null where name='andy'"
cnn.Execute SQL
SQL = "select name,age from [sheet2$A1:B5] where name is not null"

Query return no rows

I select a data from one table
select * from taxon --- it returns rows
this table has 5 columns -- branchcode, no,trackno,invno,serialno
if i use the following query
select * from taxon where branchcode='CNHJCT'
It return no rwos , but there is data
if i change the above query like
select * from taxon where branchcode like '%CNHJCT'
it returns the rows , but if i check the value of the branchcode there is no space
on both side .
How i can troble shoot this problem
rds

The is clearly some other characters to the left of the string.
Look at the output of this query, and you will probably see them.
SELECT DUMP(branchcode) col, DUMP('CNHJCT') pred
FROM taxon
WHERE branchcode LIKE '%CNHJCT'John

Sql query slowness due to rank and columns with null values:


Sql query slowness due to rank and columns with null values:
I have the following table in database with around 10 millions records:
Declaration:
create table PropertyOwners (
[Key] int not null primary key,
PropertyKey int not null,
BoughtDate DateTime,
OwnerKey int null,
GroupKey int null
go
[Key] is primary key and combination of PropertyKey, BoughtDate, OwnerKey and GroupKey is unique.
With the following index:
CREATE NONCLUSTERED INDEX [IX_PropertyOwners] ON [dbo].[PropertyOwners]
[PropertyKey] ASC,
[BoughtDate] DESC,
[OwnerKey] DESC,
[GroupKey] DESC
go
Description of the case:
For single BoughtDate one property can belong to multiple owners or single group, for single record there can either be OwnerKey or GroupKey but not both so one of them will be null for each record. I am trying to retrieve the data from the table using
following query for the OwnerKey. If there are same property rows for owners and group at the same time than the rows having OwnerKey with be preferred, that is why I am using "OwnerKey desc" in Rank function.
declare @ownerKey int = 40000
select PropertyKey, BoughtDate, OwnerKey, GroupKey
from (
select PropertyKey, BoughtDate, OwnerKey, GroupKey,
RANK() over (partition by PropertyKey order by BoughtDate desc, OwnerKey desc, GroupKey desc) as [Rank]
from PropertyOwners
) as result
where result.[Rank]=1 and result.[OwnerKey]=@ownerKey
It is taking 2-3 seconds to get the records which is too slow, similar time it is taking as I try to get the records using the GroupKey. But when I tried to get the records for the PropertyKey with the same query, it is executing in 10 milliseconds.
May be the slowness is due to as OwnerKey/GroupKey in the table can be null and sql server in unable to index it. I have also tried to use the Indexed view to pre ranked them but I can't use it in my query as Rank function is not supported in indexed
view.
Please note this table is updated once a day and using Sql Server 2008 R2. Any help will be greatly appreciated.

create table #result (PropertyKey int not null, BoughtDate datetime, OwnerKey int null, GroupKey int null, [Rank] int not null)Create index idx ON #result(OwnerKey ,rnk)
insert into #result(PropertyKey, BoughtDate, OwnerKey, GroupKey, [Rank])
select PropertyKey, BoughtDate, OwnerKey, GroupKey,
RANK() over (partition by PropertyKey order by BoughtDate desc, OwnerKey desc, GroupKey desc) as [Rank]
from PropertyOwners
go
declare @ownerKey int = 1
select PropertyKey, BoughtDate, OwnerKey, GroupKey
from #result as result
where result.[Rank]=1
and result.[OwnerKey]=@ownerKey
go

How to find using SQL query application deployed on win 7 machines with SCCM 2012 server or user installed manually.

Hi,
how to find using SCCM SQL query, application deployed on win 7 machines with SCCM 2012 server or user/technician installed manually. Please let me know.

Thanks, is it not possible via any script also?
Like Torsten said, how can you tell the difference between CM12 installed applications and locally installed? Once you can answer that, then you can write report.
