Extract data using SQL Expression
Hello, I created an intermediate table and just realized that I need some new additional fields.Should I create them in the scene or in the target table?
I want to use the SQL COUNT expression to fill these new data sources published, fields
but do not know exactly how do. I'm a little amateur.
Thank you.

Error when you try to use SQL Express 2012 import/export wizard
When you try to use 'Import and data export' Wizard SQL Server 2012 Express with Advanced Services, I get the following error message:
I tried everything I can think of. I tried to copy this .dll on various windows system files, by registering the .dll file, even tried to not downgrading from SQL Express 2016 until 2012... no luck, still the same problem. I tried everything on at least the first five pages of a Google search. I am running it in a box of Windows 7 Pro 32-bit. I used the x 86 version of SQL Express 2012 with Advanced Services and all the features were installed during the installation.
Any help would be greatly appreciated.
This issue is beyond the scope of this site (for consumers) and to be sure, you get the best (and fastest) reply, we have to ask either on Technet (for IT Pro) or MSDN (for developers)* -
How to extract data from SQL server in the FDM
Hi Experts
How to extract data from a SQL server HFM to another SQL Server using scripts for integration in FDQM?
concerning
DevCould you clarify why you want to do this?
If you try to synchronize two databases (apps) to have a backup or something running in a development environment, I suggest configuring replication between two databases. It would be much more effective to do it at the SQL Server level through the application of FDM, IMHO.

How to skip the installation of SQL Express 2005 and using SQL Express 2008 instead?

How to configure the installation of Lookout as he ignores the installation of SQL Express 2005?
Are there other measures that must be taken so that Lookout can work properly with SQL Express 2008?
Thank you.
OK - it worked.
However, for 64-bit installations, I had to use the WOW of SQL Express 2008 versions, because, the Citadel is a 32-bit database and installation of 64-bit native versions would not allow an upgrade of the Citadel of Instance.
Thank you.

If the problem I encounter is here for loading data in the link table that I check if DHCP is present in the subntwk table, then continue to another mistake of the newspaper. If CMTS then left create link to another error in the newspaper.
Now that we can here multiple CMTS are associated with unique DHCP.
So here in the table links to create the link, but for the last iteration of the loop, where I get separated by commas separate CMTS table stg_link_data it gives me log as not found CMTS.
for example
DHCP-1-1-1. WNLB-CMTS-01-1,WNLB-CMTS-02-2
Here, I guess to link the dhcp-1-1-1 with balancing-CMTS-01-1 and wnlb-CMTS-02-2
Theses all the data present in the subntwk table, but still it gives me journal wnlb-CMTS-02-2 could not be FOUND, but we have already loaded into the subntwk table.
same thing is happening with all the CMTS table stg_link_data who are in the last (I think here you got what I'm trying to explain).
But when I run the SQL scripts in the SQL Developer separately then it inserts all valid links in the table of links.
Here, she should create 9 lines in the table of links, whereas now he creates only 5 rows.
I use COMMIT in my script also but it only does not help me.
Run these scripts in your machine let me know if you also get the same behavior I get.
and please give me a solution I tried many thing from yesterday, but it's always the same.
It is the table of link log
link is already present: dhcp-1-1-1_TO_wnlb-cmts-01-1 NOT FOUND CMTS for device to create the link: wnlb-CMTS-02-2
link is already present: dhcp-1-1-2_TO_wnlb-cmts-03-3 link is already present: dhcp-1-1-2_TO_wnlb-cmts-04-4 NOT FOUND CMTS for device to create the link: wnlb-CMTS-05-5
NOT FOUND CMTS for device to create the link: wnlb-CMTS-01-1
NOT FOUND CMTS for device to create the link: wnlb-CMTS-05-8 NOT FOUND CMTS for device to create the link: wnlb-CMTS-05-6 NOT FOUND CMTS for device to create the link: wnlb-CMTS-05-0 NOT FOUND CMTS for device to create the link: wnlb-CMTS-03-3
link is already present: dhcp-1-1-5_TO_wnlb-cmts-02-2 link is already present: dhcp-1-1-5_TO_wnlb-cmts-04-4 NOT FOUND CMTS for device to create the link: wnlb-CMTS-05-7
Device not found: wnlb-dhcp-1-13 IF NEED MORE INFORMATION PLEASE LET ME KNOW
Thank you
I felt later in the night that during the loading in the staging table using UNIX machine he created the new line for each line. That is why the last CMTS is not found, for this I use the UNIX 2 BACK conversion and it starts to work perfectly.
It was the dos2unix error!
Thank you all for your interest and I may learn new things, as I have almost 10 months of experience in (PLSQL, SQL)

Without regexp? It depends on your comments... If you know a definitive character set you want to replace, and then you can go for:
(strictly dependent on your entry in the question)
SELECT TRANSLATE)
SUBSTR (RTRIM (str, '_'), INSTR (RTRIM (str, '_'), '_',-1) + 1);
'~c_',' ')
Str
T;
See you soon,.

Extract data from SQL to Pivot Table/CUBE database vFoglight?
Our CIO request hourly data so he can create a history of our virtual environment using the data collected from vFoglight the BODs to attend so that they can see ho are we utulizing the new environment, they allowed us to buy. I've created a report for him but he won't have to copy and paste data in an excel file, every hour, it's short.
It looks like this:
dnsName Name Use (%) ESXi Server 1 Memory 42 ESXi Server 2 Memory 37 So is there a way to allow Excel to connect to SQL Server and extract this data so that it can organize itself? Or can we write a report that displays data on time as follows?
I.E.
01:00 - 42%
02:00 - 39%
03:00 - 41%
Hi Morgan,.
There are a few examples of the extraction of metrics data formatted in Foglight using command-line scripts in the blog article Foglight Reporting using queries metric or Groovy to http://en.community.dell.com/techcenter/performance-monitoring/foglight-administrators/w/admins-wiki/5654.foglight-reporting-using-metric-queries-or-groovy
I hope this will give you some ideas.
Kind regards

Select quarterly data using SQL
All-
The database version that I use is 10.2.0.4.0
This is probably simple, but for the life of me, I can't understand it. I have a table of approximately 200 Codes and a table that contains millions of records that are obliterated (data are from 1995 to sysdate). I need a query for a view to be used in a report that will show you the different codes used by the employee for specific areas based on a date parameter. If they have no data for this quarter I want to still show the quarter show 0 for the number.
I created this simple example. If I see someone how I can integrate this logic in what I do.
SQL for the test data:
create the table bunch_of_codes
(id_code number (12) primary key,)
Description varchar2 (10));
insert into bunch_of_codes
values (1, 'APPLE');
insert into bunch_of_codes
values (2, 'ORANGE');
insert into bunch_of_codes
values (3, 'GRAPE');
create the table bunch_of_data
(id_code, number (12),)
date of activity_date,
CONSTRAINT data_id_code
FOREIGN KEY (id_code) REFERENCES bunch_of_codes (id_code));
INSERT INTO bunch_of_data
VALUES (1, to_date('4/12/2011','MM/DD/YYYY'));
INSERT INTO bunch_of_data
VALUES (1, to_date('6/1/2011','MM/DD/YYYY'));
INSERT INTO bunch_of_data

INSERT INTO bunch_of_data

INSERT INTO bunch_of_data
VALUES (3, to_date('11/11/2011','MM/DD/YYYY'));
COMMIT;
What I see when I run the SQL statement is:
DESCRIPTION QUARTER COUNTY
----------- ------- -----
APPLE 1 0
2 2 APPLE
APPLE 3 0
APPLE 4 0
1 1 GRAPE
1 2 GRAPES
GRAPES 3 0
4 1 GRAPE
ORANGE 1 0
ORANGE 2-0
ORANGE 3 0
ORANGE 4 0
I need each printed code without worrying if it was not used. If it has not been used, I want to still see each quarter but show 0 for count.
For this example, I can run this SQL to join the data:
Select c.description,
to_char(d.activity_date,'Q') quarter,
Count County (d.id_code)
of bunch_of_codes c,.
bunch_of_data d
where c.id_code = d.id_code
C.description group, to_char(d.activity_date,'Q')
order of description, quarter
But if it is not no matter how much detail for the quarter then I don't get a row of data. I tried all sorts of things, but nothing seems to work.
Please help if you have any ideas.Hi MLBrown,
Here's a query that gives what you asked.
Note: My table bunch_of_data has three lines that you have published, more a fourth line (the activity_date of this row is April 12, 2010, in the format DD-MON-YYYY).
To account for the response you gave to the question of Etbin, a column Y (for data year) is included in the output. In this output, there is for the year, Q for the quarter and the total for the count.SQL> select * from bunch_of_codes; ID_CODE DESCRIPTION ---------- ----------- 1 APPLE 2 ORANGE 3 GRAPE SQL> select * from bunch_of_data; ID_CODE ACTIVITY_DATE ---------- --------------- 1 12-APR-2010 1 12-APR-2011 1 01-JUN-2011 3 15-JAN-2011 3 17-APR-2011 3 11-NOV-2011 6 rows selected.
