Data server switch in SQL query

Hi guys,
I have a question about data server switch in the sql query template. We have been developing all the sql queris pointing to the customer test db server say "TESTDB", now we have to change the db connection to "PRODUCTDB", do we need to change sql queries one by one or is there a better solution for this? I think this is a common requirement to change back and forth data server connection for a bulk number of queries
Thanks,
Tony.

Tony,
From a design perspective it is advisible to name your data servers in a more abstract way, since the query templates themselves only save the Name of the data server in them. Data Servers also have a description field (typically overlooked) which will appear in the list and the workbench where you can be explicit or to even serve as a reminder that you are working with either test or production data. The true 'switch' should happen when you reconfigure your data server settings for server url and user/pwd.
TESTDB and PRODUCTDB might be better served with a meaningful name that provides a correlation to the data stored in the database. In more mature system landscapes having a DEV/QA/PROD arrangement of MII servers, the ability to promote content comes from configuration and projects, not from actually changing the content on the same server.
If you need to rapidly modify your content to adopt this practice then I would simply export the associated project and unzip it to a folder. Then use windows explorer to do a search for files containing your data server name (they will appear in your query templates as Server="TESTDB"). With a text editor that can do search and replaces across multiple files (http://www.editplus.com is my personal favorite) you can easily change the data server name to a better convention. Then zip up the folder content and reimport the project. This will effectively switch your data servers (don't forget to create the new abstract data server in place of the TESTDB and PRODUCTDB).

Default Data Server for Hypersonic SQL in ODI 11g

Hi All,
I installed ODI 11g 11.1.1.6.0 for Win 7 with 10g DB R2 and WLS 10.3.5 successfully without any issues.
Created DEV_ODI_REPO Repository also without any issues.
Created Master Repository snpm1 and Work Repository as snpw1.
Created the Agents (Physical and Logical) and tested successfully.
Created the data servers for respective technologies
1) Technology Oracle -
    Data Server - ORACLE_ORCL_LOCAL
    Physical Schemas - SALES_DEV & SALES_PROD and
    Logical Schema as ORACLE_ORCL_LOCAL_SALES
2) Technology FILE -
    Data Server - FILE_GENERIC
    Physical Schema - FILE_GENERIC.E:/oracle/Middleware/Oracle_ODI1/oracledi/demo/file
    Logical Schema - FILE_DEMO_SRC
3) Technology - XML
     Data Server - XML FILE
     Physical Schema - GEO_D
    Logical Schema - GEO_DIM
4) Technology - Hypersonic SQL
     Data Server - HSQL   (Is this the correct name or some other name is recommended ? )
     Physical Schema - HSQL_LOCALHOST_20001_Default and HSQL_LOCALHOST_20001_Default
    Logical Schema - HSQL_DEMO_SRC and HSQL_DEMO_TARG
All the Mappings are done properly using Development & Production context for Physical and Logical Schemas.
I am able to create the Models for Oracle, FIle and XML with successful Reverse Engineering (standard with development context )
with all the data displayed correctly.
The issue starts here
The Main issue is for Hypersonic SQL where I am not able to get the Reverse Engineering.
Technology - Hypersonic SQL I have defined the data server as HSQL
Is this correct data server or some other name for data server is suggested ?
I am able to start the startdemo.bat file successfully opening the 3 dos prompt windows as
a) Oracle DI Demo - Repository Server
b) Oracle DI Demo - Source Server
c) Oracle DI Demo - Target Server
Later I make entries on the JDBC tab od HSQL - Data Server as
JDBC Driver : org.hsqldb.jdbc.JDBCDriver
JDBC Url : jdbc:hsqldb:hsql://localhost
Test Connection - ok with successful connection.
Prior to this I already run the script created schemas and inserted data to the SRC_ tables in my 10g Database as
ORDERS - containing the Tables as SRC_CITY, SRC_CUSTOMER, SRC_PRODUCT, SRC_REGION.....
In the Designer I create a new Model as HSQL_SRC
Technology - Hypersonic SQL
Logical Schema - HSQL_DEMO_SRC as defined earlier in logical schema.
Reverse Engineer Tab - Selected as Standard   Context selected as Development from drop down list.
When I right click on HSQL_SRC model for reverse engineer, it executes, however it does not display any tables inserted
as shown for ORDERS Schema.
Please correct me where I am wrong in giving the name for data server ? or some other place.
Thanks
Ajaz

Hi,
according to docs
http://docs.oracle.com/cd/E23943_01/integrate.1111/e12644/hypersonic_sql.htm#ODIKM590
i see
JDBC Driver: org.hsqldb.jdbcDriver
JDBC URL: jdbc:hsqldb:hsql://<host>:<port>
could you modify
JDBC Driver : org.hsqldb.jdbc.JDBCDriver
JDBC Url : jdbc:hsqldb:hsql://localhost
according to docs?
Thanks

Sorting of Date field in the SQL Query useing ORDER BY

Hi
I am facing a problem when I am getting the results of a query from the ORacle 8i database using jdbc connection.
The query is having a date field and I have to sort the query results using ORDER By for the Date field. The query is giving exact results in the SQL PLus interface.
When I am getting this results in the GUI where servlets are being used an Exception is coming as not supported RefreshRow method.
If anyone has faced this problem and have got the solutions please let me know.
thanks
sulfy

That doesn't sound at all like an SQL problem.
More like you trying to do updates on the resultset which is not allowed ...
send a some code (not to much pls :) and we'll be

Hi Purvesh,
Apologize for not giving the sufficient information.
max(fcr.actual_start_date) = here I am getting date with time (for eg :9/4/2012 6:47:49 PM)
Datatype for this column is date.
This actual start date I am storing in varchar2 variable and then converting this value to date with time.
My requirement is to pick the rows between the two timestamps which I am unable to do in the procedure.

YOu are losing the Time information while fetching the data into a VARCHAR2 variable. change the datatype of v_date to DATE and get rid of the TO_DATE logic in cursor and simply use v_date variable.

How to replace a dates on a SQL query on Visual Studio (and get the query to work in there in the first place)?

Morning all,
I've just been assigned a report-related project but I have not created much of anything in C# or .Net before!
I was wondering if someone could help me get started. Here are the specifications:
Basically, I am to create an automated report application. I have the query and I will include it further down
in this post. The page is to have a couple blanks to specify the Start Date and End Date and replace those dates in the query, and generate the report. What I need some help on is how to make the SQL query work in the application which I will connect to the
intended database to generate the report (basic I know, but I'm new at this) on Visual Studio 2010. I also need some help on programming the Start Date blank and End Date blank so that what the user types in for those blanks will replace the date fields in
the SQL query, then generate the report with the new dates.
I appreciate the help!
The SQL query and what the dates are replacing:

Try this code. The Server name will be the same name when you use SQL Server Management Studio (SSMS). It is in the login window for SSMS. I assume you are using SQLSTANDARD (not SQLEXPRESS) which is in the connection string in the code

Could you elaborate more on what this code does in general?
Does it generate a table with the data between specified dates? If so, where is the table shown?
Where does one enter in the specified start and end dates on the Web Application? Do I have to create start and end date blanks and link them to the code for it to work?
Sorry for the inconvenience - I'm just really new at this. Thanks!

Date parameter to SQL query

Hi,
I am using from_date and to_date parameters. Data type and Param type for both are 'Date' and my Format string is 'dd/MM/yyyy'
I need to pass these two values to my data model which is SQL query. Whenever I use below WHERE clause I am getting
"ORA-01858: a non-numeric character was found where a numeric was expected", Please let me know how to fix this error.
trunc(a.scan_timestamp) between to_char(to_date(:p_from_date,'DD/MM/YYYY'),'DD-MON-YYYY') and
to_char(to_date(:p_to_date,'DD/MM/YYYY'),'DD-MON-YYYY')

Hello,
if you choose Date for Data type and Parameter Type for the parameters then the format of your date has nothing to do with your selection.
Please try
trunc(a.scan_timestamp) between :p_from_date and :p_to_date

Different LOV behavior between SQL query data model and data template

I have noticed different behavior when using parameters linked to list of values (LOV) of type menu with the multiple selection option enabled and a SQL query data model vs a data template. Here's the example because that first sentence was probably really confusing.
SQL Query:
select
plmc.MonthCode, plmc.ModalityDim, plmc.ModalityName,plmc.RegionDim
from
DataOut.dbo.PatientLabMonthlyCross plmc
where
plmc.MonthCode = 200202
and plmc.RegionDim = 1209
and 1 =
case
when coalesce(:modalityDim,null) is null
then 1
else
case
when plmc.ModalityDim in (:modalityDim)
then 1
else 0
end
end
Putting BI Publisher into debug mode, defining a data model of type SQL Query, defining a parameter called :modalityDim linked to a LOV that allows multiple selections, and selecting a couple of values from the LOV the output of the prepared statement is:
[081607_122647956][][STATEMENT] Sql Query : select
plmc.MonthCode,
plmc.ModalityDim,
plmc.ModalityName,
plmc.RegionDim
from
DataOut.dbo.PatientLabMonthlyCross plmc
where
plmc.MonthCode = 200202
and plmc.RegionDim = 1209
and 1 =
case
when coalesce(?,?,null) is null
then 1
else
case
when plmc.ModalityDim in (?,?)
then 1
else 0
end
end

When I use this same SQL Query in a data template the output is:

Note the exception because it is trying to convert the multiple parameter values.
Am I doing something completely wrong here? I really need to use a data template because I will need to link a couple of queries together from different database vendors.
-mark

This is for 10.1.3.4 - because in 11g every SQL query is automatially part of a data model.
In 10g SQL query is for simple unrelated SQL queries.
If you need to use advance features such as:
a) multiple SQL queries that are joined in master-detail relation ships
b) before/after report triggers
Then you will need to use the data template, which is an XML description
of the queries, links, and PL/SQL calls.
hope that helps,

SCOM SQL Query to find Mail Latency (Send/ Receive) Data.

Hi,
I unable to find Mail Latency (Send/ Receive) Data in SCOM 2012 SQL Query.
need your help to find SQL query that fetches below details
1. Average Time for Accessing Mailbox.
2. Average Time to Send and Receive Mail.
Regards,
Vinoth Kumar.

Hi Vinoth
There are no specific tables storing the mailbox related data.
To find information about Exchange in SCOM you need the Exchange management pack for the version of Exchange you are running, as well as monitoring the Exchange servers.
When that has been done you can find reports and performance views for Exchange.
I am unsure if you can find this specific information for Exchange in SCOM, i would look into the management pack. If you cannot find the information, i suggest you consult your Exchange administrator to get this information.

401 Unauthorized after too many tables in AXL SQL Query

Hi...
I have an app that sends several AXL calls. All work fine with the exception of one accessing MGCP data via the AXL SQL QUERY command. I have found that if I only do a couple of tables it works fine, but if I had in more than 3 I get a 401 unauthorized return. Now, I know the commands are built correctly becuase its working for every other command in the set and like I said if I only do 3 or less tables the query works. Also, if I SSH into the CM locally and do run sql with the full command, it returns all tables fine, which leads me to believe this is a restriction in the return of the axl soap call...
Help?
I am using CM 6.0. The full query being passed in that returns 401 unauthorized is:
SELECT MGCP.pkid, MGCP.DomainName, TypeProduct.Name AS GatewayProduct, CallManagerGroup.Name AS CallManagerGroup, MGCPSlotConfig.Slot, TypeMGCPSlotModule.Name AS UnitModule, MGCPSlotConfig.Subunit AS SubUnitIndex, TypeMGCPVic.Name AS SubUnitProduct, TypeMGCPVic.MaxNumPorts, MGCP.VersionStamp, MGCP.SpecialLoadInformation FROM TypeMGCPVic RIGHT OUTER JOIN MGCPSlotConfig ON TypeMGCPVic.Enum = MGCPSlotConfig.tkMGCPVic LEFT OUTER JOIN CallManagerGroup RIGHT OUTER JOIN MGCP ON CallManagerGroup.pkid = MGCP.fkCallManagerGroup LEFT OUTER JOIN TypeProduct ON MGCP.tkProduct = TypeProduct.Enum ON MGCPSlotConfig.fkMGCP = MGCP.pkid LEFT OUTER JOIN TypeMGCPSlotModule ON MGCPSlotConfig.tkMGCPSlotModule = TypeMGCPSlotModule.Enum ORDER BY MGCP.DomainName, MGCPSlotConfig.Slot, UnitModule DESC, MGCPSlotConfig.Subunit"
Again, this works locally on the CM machine, it works if I pull back some of the tables... The AXL trace logs do not have errors, they just stop (with a return soap call that isnt passed back because 401 is recieved).
Thanks!

Here is the trace log. The return is there! It just never gets recieved.

Sql query slow in new redhat enviornment

We just migrated to a new dev environment in Linux REDHAT5, and now the query is very slow, and I used the TOAD to run the query, it took like 700 msecond to finish, however from any server connection, the sql query takes hours to finish.
I checked toad monitor, it said need to increase db_buffer_cache and shared pool too small.
Also three red alert from toad is:
1. Library Cache get hit ratio: Dynamic or unsharable sql
2. Chained fetch ratio: PCT free too low for a table
3. parse to execute ratio: HIgh parse to execute ratio.
App team said it ran real quick in the old AIX system, however I ran it in old system, and monitored in the toad, it gave me all same 5 red alerts in old system, and it did provide query results a lot quicker though.
Here is the parameters in the old system (11gr1 on AIX):

As for the SQL query being slow. It is not.
You have not provided any evidence that it is slow. And no, comparing performance with a totally different system is not a valid baseline for comparison. (most cars have 4 wheels, a gearbox and a steering wheel - but that does not mean you can compare different cars like a VW Beetle with a VW Porsche)
What is slow? What are the biggest wait states for the SQL? What does the execution plan say?
You have not defined a problem - you identified a symptom called "+query is slow+". You need to diagnose the condition by determining exactly what the SQL qeury is doing in the database. (and please, do not use TOAD and similar tools in an attempt to do this - do it properly instead)

Repair Problem with Excel Removing All But First External SQL Query Tables

We have an Excel 2007 XLSX workbook that we created for doing some business analysis from the SQL database that contains data from our MRP system. It started as a single sheet with one data connection running a SQL query. The data comes into
the spreadsheet as a table and there are some basic row and column sums being done.
After getting the first version up and running without problems, we decided to add some additional sheets to the same workbook. Since each of these additional sheets had only slight variations to the SQL query and the formatting was all to be the same, we
simply copied the first sheet and modified the data connection for each successive sheet (each copy automatically created a copy of the data connection as well). Everything seemed to be up and running properly, so we saved and closed the workbook.
A little bit later, the same workbook was re-opened and Excel reported that "Excel found unreadable content in '<file name>'. Do you want to recover the contents of this workbook? If you trust the source of this workbook, click Yes." If Yes
is clicked, then Excel indicates the repairs that were made. Only one was made for each sheet beyond the first and that was "Removed Part: /xl/queryTables/queryTable2.xml part. (External data range)". The result was that the data connection
was deleted from every sheet other than the first and only static data left in place.
We thought it might have actual been some corruption, so we deleted the static sheets and recreated them the same way. After saving and closing, re-opening the file resulted in the same problem. It seems that Excel is somehow saving data that it can't read
when it opens. I would think it could be something in the SQL query, but all sheets have essentially the same SQL query, so I'm not sure why the first sheet survives. As a result, I think it must be something that it does in copying the sheet and the corresponding
data connections, but I'm not sure.
I think this might be some kind of bug, but would like to know if anyone else has encountered a similar problem and found a solution. A few internet searches didn't give me much to check out.
Thanks in advance,
indyvql

KR,
Thanks for your response. I don't think it applies in this case since the file was created brand new in Excel 2007 and used in the same. There was no 3rd-party program involved. I'm also not migrating from 2003 to 2010 as the stellarinfo.com article
suggests. Some of the other suggestions there also don't make any difference as all the data links are lost on opening the worksheet, so copying and pasting doesn't do any good.
I tried to create a simple example by creating a new workbook with a sheet with a very simple SQL query ("select * from X where a > b"), but in that example it worked fine. I'm guessing there is something key about the much more complex SQL query
in my original file with the problem, but I'm not sure why it would only affect copies of the data connection and not the original data connection itself.
Thanks,
indyvql

Insert String Using SQL Query

Hi, EveryOne,
I tried to insert(update) a string data type using Fixed SQL Query as, for a example:
insert into Masters(MasterName) values([Param.1])
In html form I enter a value in field and press button to call the function. But if enter in the field a String value - nothing inserted in table but if I enter Number - everything works fine. I tried to use commas but the effect is the same.
Thnks,
Serj

Hello Sergey,
Ryan's sql statement is right. The ' sign is used to mark the [Param.1] as a string.
The sql statement (connection) is language independent, but you have to make sure that you mark up strings and timestamps in the correct way.
In your first statement
Masters(MasterName) values([Param.1])
xMII will replace [Param.1] with the value you type in("yourvalue"). For strings("yourvalue") it will look like this
Masters(MasterName) values(yourvalue)
this should bring back a sql error. You can try it in another sql client.
Hope this help as an explanation.
Regards,
Martin
