Set substitution variable from Sql table

Hi guys,
I am new to sql/unix so I hope you can guide me in the right direction.
whats the easiest way to update an essbase subvar from a sql table?
would I have to write a sqlplus statement to output the variable to file,
read the file in a maxl command and set the variable and call these commands using .sh script and esscmd?
is there a more efficient way to set the variable? e.g only use sqlplus and esscmd?
thanks in advance,

Try something like this
echo off
sqlplus -s username/passwordusername/password@server/SID:@server/SID:port @test.sql > variable.txt
for /f "usebackq delims=" %%a in (variable.txt) do set CurrentMonth=%%a
echo %CurrentMonth%
See whether you are getting the correct month.

Essbase server - automatic change of substitution variable from SQL

Hi,I would like to automaticaly change the substitution variable in Essbase Server. Is it posible to change the substitition variable from external source e.g. SQL statement?Simple sample:I would like to assign value "2003" to "CurYear" substitution variable. But value "2003" I would like to get from SQL:"select year(current date) from table".There are commands in Esscmd and MaxL Shell, see bellow.Esscmd command:CREATEVARIABLE "CurYear" "localhost" "" "" "2003";MaxL Shell:alter system set variable CurYear '2003';Is it possible to get the value '2003' from SQL and pass this value to Esscmd command or MaxL Shell?My system:Windows 2000 Professional Service pack 4Essbase at 6.5.3 levelThanks,Grofaty

You can create a text file from the SQL server that writes the command like"CREATEVARIABLE "CurrYear" "Servername" "AppName" "DBName" "2005";then you can create a schedule job that would run this script which can update the variable. CREATEVARIABLE creates/replaces the current variable.

Pull data from SQL Table and display it in mail

I have a requirement to pull the data from SQL table and send it in email. Currently I am sending the hard coded info in email but is it possible to pull some data from SQL Table and than format it and send it across in the same email?
Can you guide me with steps on this.
Neil

There are several ways to do this. First is to populate a file in a data flow and then send that as an attachment in the send mail task.
As far as including the results in the email body this becomes a bit trickier. To use a variable you would need to use an SSIS variable type of
Object, this is similar to a collection in .NET. The problem once the object is populated is that it isn't like a readable result set, but again more like an array or a collection. There is no native method to take the object variable and
specify .ToString() or cast its results as text. You would need to iterate through each row and append it to another variable of type string, this could be done with a script task or ForEach container.
Also you mentioned formatting the results. What type of formatting were you looking for. A limitation of the SMTP send mail task is that the message body doesn't support HTML so if you were looking at creating a table within the mail body you
would have to use a script task or a custom component

Regarding hierarchy creation from sql tables using db / ud connect

bw version 3.0 upgrading to 7.0
sql version 2005.
we had built a sql data mart which is being accesses by a number of reporting tools. BI is one of the systems connected to it. My requirement is to upload hierarchies like customer from the sql data mart in to BW.
The sql tables are in a denormalized format like this,
EMPLOYEE_ID LAST_NAME                 MANAGER_ID      LEVEL
        101 Kochhar                          100                             1
        108 Greenberg                        101                            2
        109 Faviet                           108                                3
They say that all third party reporting tools will recognize the above format and it universal. <b>I wanted to know is there any setting in bw that will allow extraction of hierarchies from the above table format ? if not I can only think of arranging data in the format of BW transfer structure, similar to flat file load.</b>
I want to know can I upload hierarchies from sql tables or should I create flat files from tables ?
Inputs will be awarded points.

Set 2 variables (PL/SQL)

Hi,
I would like to set 2 variables PL/SQL with a query like that :
SELECT FINAC_USER.NM_FIRST_NAME INTO FIRST_N,
FINAC_USER.NM_LAST_NAME INTO LAST_N
FROM FINAC_USER
WHERE FINAC_USER.CD_USER = CODE_USER;
But Oracle sends me an error :
PL/SQL: ORA-00923: FROM keyword not found where expected
How can I do that ?
Thank you for your help.

anutosh, please do not answer questions that have already been answered. You have done that several times here now. It is not a good use of our time to open up a thread and see that the only new entry is the rewording of a valid answer already provided.

Fill Variables From a Table

I have a requirement to write a query which is much like an aged debt report.
I would have a number of variables which will allow the user to create buckets of data, i.e. invoices that are not yet due, 30 days overdue, 60 days overdue, 90 days overdue, etc. However, the data will be coming from CRM, and I would like to pre-fill the variables from a table, and not have the user enter them every time they wish to run the query. The table containing the variable values will also be extracted from CRM into BW.
Does anybody have any idea how I can pick the bucket parameters up to use in my query?

Stuart,
if you know already how to build and fill this kind of variable (but for other purpouse), you start from a very good point !!!
It's enough to do a select onto the table on which you pass the relevant values (do you need some ABAP sample ? with the search engine you can find a lot of good example) ...or do you have problem to pass these values from CRM environment...let us know if you need some more specific!
Bye,
Roberto
(about point, I think it's enough to hit the radiobutton that you should find in every answer...if there is some problem, write an e-mail to [email protected] or wait for some minute..)

Substitution variable in sql load rules file

Okay gurus,
I need a little guidance, I have to replace the value of 201020 and 2008 from substitution variables. I have created the variables and set them up globally on the essbase server.
201020 = FW00
2008 = FY00
WHERE ACT.FISCAL_WEEK_ID <= 201020
AND ACT.FISCAL_YEAR_ID > 2008
AND RTDIV.DIV IN (1,2,3,4,5,6,7,8,9,99) (This is the query with hard coded values of week and year)
When i m trying to put sub variables there , its throwing the error. please find below the way i was trying to do it.
WHERE ACT.FISCAL_WEEK_ID = '&FW00'
AND ACT.FISCAL_YEAR_ID = '&FY00'
But unfortunately, its throwing error Error: 1021001 Failed to Establish Connection With SQL Database Server. See log for more information
I know that this is the generic error because if i put the hard coded value in sql load rules it works fine.
Is it the right way to out sub var in sql load rules???
Please advice and thanks in advance.

Hi Genn,
I tried to see the app log for sql but i m afraid that there is nothing in there, the only error message which I am getting in app log is this:
Failed to Establish Connection With SQL Database Server. See log for more information
Its an ASO cube and initially i was using the variable as FY00 AS "2008" it did not work and than i tried without quotes in variable but is still not working.
Any idea..thanks in advance.

Can I create ASP user validated website using existing MD5 passwords from SQL table?

I'm attempting to build a user authenticated site in Dreamweaver CS5 using an existing USERS table from another site. The password field in the existing SQL table appears to be MD5 encoded. How can I MD5 encode the form field (or the SQL query) so that it verifies MD5 to MD5?
Currently, it's comparing the form's plain text field to the MD5 encrypted password field in SQL.
I've built a simple login form using the following:
<form id="form1" name="form1" method="POST" action="<%=MM_LoginAction%>">
    <input name="username" type="text" id="username" accesskey="u" tabindex="1" /><input name="password" type="password" id="password" accesskey="p" tabindex="2" /><input name="submit" type="submit" value="submit" />
    </form>
With the stock Dreamweaver Log In User Server Behavior as follows:
<%
' *** Validate request to log in to this site.
MM_LoginAction = Request.ServerVariables("URL")
If Request.QueryString <> "" Then MM_LoginAction = MM_LoginAction + "?" + Server.HTMLEncode(Request.QueryString)
MM_valUsername = CStr(Request.Form("username"))
If MM_valUsername <> "" Then
Dim MM_fldUserAuthorization
Dim MM_redirectLoginSuccess
Dim MM_redirectLoginFailed
Dim MM_loginSQL
Dim MM_rsUser
Dim MM_rsUser_cmd
MM_fldUserAuthorization = ""
MM_redirectLoginSuccess = "results.asp"
MM_redirectLoginFailed = "error.html"
MM_loginSQL = "SELECT user_name, password"
If MM_fldUserAuthorization <> "" Then MM_loginSQL = MM_loginSQL & "," & MM_fldUserAuthorization
MM_loginSQL = MM_loginSQL & " FROM dbo.users WHERE user_name = ? AND password = ?"
Set MM_rsUser_cmd = Server.CreateObject ("ADODB.Command")
MM_rsUser_cmd.ActiveConnection = MM_ADSX_STRING
MM_rsUser_cmd.CommandText = MM_loginSQL
MM_rsUser_cmd.Parameters.Append MM_rsUser_cmd.CreateParameter("param1", 200, 1, 32, MM_valUsername) ' adVarChar
MM_rsUser_cmd.Parameters.Append MM_rsUser_cmd.CreateParameter("param2", 200, 1, 32, Request.Form("password")) ' adVarChar
MM_rsUser_cmd.Prepared = true
Set MM_rsUser = MM_rsUser_cmd.Execute
If Not MM_rsUser.EOF Or Not MM_rsUser.BOF Then
    ' username and password match - this is a valid user
    Session("MM_Username") = MM_valUsername
    If (MM_fldUserAuthorization <> "") Then
      Session("MM_UserAuthorization") = CStr(MM_rsUser.Fields.Item(MM_fldUserAuthorization).Value)
    Else
      Session("MM_UserAuthorization") = ""
    End If
    if CStr(Request.QueryString("accessdenied")) <> "" And false Then
      MM_redirectLoginSuccess = Request.QueryString("accessdenied")
    End If
    MM_rsUser.Close
    Response.Redirect(MM_redirectLoginSuccess)
End If
MM_rsUser.Close
Response.Redirect(MM_redirectLoginFailed)
End If
%>
Please help!

unfortunately classic asp does not have a built in function for md5. what we used for our legacy sites is a javascript that hashes a string to MD5. here's the code we've used in the past http://pajhome.org.uk/crypt/md5/md5.html
your asp should have something like this...
<script language="jscript" src="path_to_js_file/md5.js" runat="server"></script>
<%
'hash the password
Dim md5password       ' md5password variable will hold the hashed text from form variable txtPassword
md5password = hex_md5(""&Request("txtPassword")&"")
' based on the code you posted...
MM_rsUser_cmd.Parameters.Append MM_rsUser_cmd.CreateParameter("param2", 200, 1, 32, md5password) ' adVarChar

Using substitution variable in sql -- Issue

Hello All
I am trying to do a sql operation from command prompt of my system and that sql requires substitution variable which i am passing it but when i pass the variable ( there are two) the first one assign as " \c" and second gets both what i am passing.
I am not sure what exactly happening here, i have done this on AIX but here its not working any ideas?
System : uname -a
Linux ## 2.6.18-128.1.1.el5 #1 SMP Mon Jan 26 13:58:24 EST 2009 x86_64 x86_64 x86_64 GNU/Linux

AIX and Linux are not the same. An output of "\c" may indicate a compatibility issue of your shell script with your current command line interpreter (shell). A \c can be used to suppress a newline with the echo command. Bash understands both formats echo -n and echo \c, but other shells like Ksh don't. Try to run your script under a Bash, which is the default under Linux. If the problem persists you will need to post your script for any further analysis.

Error with define substitution variable in SQL

Hi there,
I am using PL/SQL developer and trying to define a substitution variable as follows:
define freq = 'Weekly'
Then later on, in my SQL statement, I used this variable in WHERE statement as follows:
WHERE ... (&freq = 'Weekly') and ...
But I got the "ORA-00904: "WEEKLY": invalid identifier" error.
Where is the problem?
Thanks in advance!

I don't know about PL/SQL developer but in sqlplus you need single quotes around the variable.
SQL> define freq = 'Weekly'
SQL> select null from dual
2 where &freq = 'Weekly';
old   2: where &freq = 'Weekly'
new   2: where Weekly = 'Weekly'
where Weekly = 'Weekly'

Dynamically Setting a Variable from a Connection String that has been set by a Config File

Hi Guys
I'm setting up a Master / Slave (Parent / Child) dtsx environment but I'm unable to work out how to dynamically set a variable in the Master dtsx from a connection string that has had its value set by a config file. I'm sure it's possible.
Below is the what I'm hoping to achieve. I've set up everything apart from the highlighted section.
Any ideas?

First, what version of SQL Server are you using?
You could switch the problem around. You could set the value of a variable from the config file, then it is easy to use that variable as the connection string source for your connection manager. At the same time you can use a parent variable
configuration to map that variable to variables in your child package.

Substitution variables in Sql*Plus

Hi all,
How to make Sql*Plus ask for the substitution variable value one time only for a substitution variable even if it appears multiple times inside a query ? Because so far each time I launched the query below then I have been asked two times by Sql*Plus for the variable value. For example : select ref_site from t_comsis where longitude_lamb + latitude_lamb < &distance + power(&distance,2).
Thanks

of course accept is more friendly, you can check for valid number, you can have a prompt or a hidden input.
you can also undef your variable if you prefer the && solution
SQL> select &&x+&&x from dual;
Enter value for x: 1
old   1: select &&x+&&x from dual
new   1: select 1+1 from dual
       1+1
         2
SQL> undef x
SQL> r
1* select &&x+&&x from dual
Enter value for x: 2
old   1: select &&x+&&x from dual
new   1: select 2+2 from dual
       2+2

Setting substitution variable to connection string (not ODBC name)

Hi,
I havce a question regarding the use of a sub variable in SQL data loads as the data source. I find this works great when the variable is set to an existing ODBC. What I would really like to do is skip the ODBC creation step and have the substitution variable be the actual connection string, such as "Driver={SQL Native Client};Server=myServerAddress;Database=myDataBase; Uid=myUsername;Pwd=myPassword;"
Can anyone confirm or deny whether this functionality exists? As usual, the documentation is vague on the subject and doesn't exclude the possibility, but doesn't include it, either.
Thanks!

My first thought is that no, you can't do that. Even if you could, I'm not sure if you'd want to do that. The easiest way to find out is simply to try. But more than likely I think you should just have "hard-coded" values for the source/target server. If you are trying to stay with the same load rule for dev/test/prod servers, you might just be better off coming up with a naming scheme that let's you keep them all separate.
Cheers,
