How to execute a select statement in unix shell script

Hi,
How to execute the below statement in unix shell .
select count( ID) into v_count from tbl_data1
where ID =V_ID;
thanks
BCJ

Thanks for the reply.
few more doubts,
the V_ID value is a user input getting inside the unix script, so how can i pass the value in to the a.sql.
also needs the v_count value inside the unix script for further process.actual requirement is like,
declare
v_count number;
begin
select count( ID) into v_count from tbl_data1
where ID =$V_ID;
if v_count>1 then
process 1;
else
process2;
end if;
end;
thanks a lot

How to execute a SELECT statement in java??

Hello !!
In my java program , i need to delete a record of number X, so
i accept the number X from the keyboard
Then before deleting it
i want the program to show me the name, age of the record which has the number X
How to do this

hello kylas
actually i didnt get why this program example?? wats
its executing ??? Look at reply #3 in your other thread:
http://forum.java.sun.com/thread.jspa?threadID=713289&messageID=4126346
Notice the similarity? You've now asked "How to delete a record in Java" and "how to execute a select statement in java". You may have noticed that, aside from the SQL and the call to execute and executeUpdate (for delete) it's the same code. This is because you don't so much do these things in Java, you do them in SQL. The Java code simply asks the Driver to execute whatever SQL you write. So, I really hope your next post isn't "how do I execute an UPDATE statement in Java".
Good Luck

Unix shell script should execute (run) webI report.

Hi
i am new to BO.
I have webI reports developed, can any one tell me how to execute a webI reprot using unix sheel script.

Hello Vijaya,
Thatu2019s an interesting question. BusinessObjects does not supply any native UNIX shell interfaces or scripts for running/executing Webi Reports. Not knowing what it is you are exactly trying to accomplish Iu2019ll give a very general answer.
I have had several customers who had requirements to have external systems execute, refresh and export reports in BusinessObjects Enterprise before. These external systems could execute a shell script so what they have ended up doing is creating generic Java applications that use the BusinessObjects BOE Java SDK. Once they had the Java application created their external application could execute a java directory or they created shell wrappers that were called. So what you could do is create some Java applications that wrap the functionally you need and then execute those from the command line.
With that said there is a lot of functionally built into BusinessObjects Enterprise. If I was to know exactly what you were trying to achieve I might be able to point you in the direction of an existing product feature.
Cheers,
David.

Executing java from unix shell script

Sounds like you either have a corrupt class file or you're using an older version of the JVM to try to execute classe that were compiled for a newer version.

How to test the select statement.

Hi All,
How to test the select statement.
Is there any Oracle sqlplus or toad kind of tool to test the query.
thanks
siva

Use SQL Trace (ST05) and choose 'Explain one SQL Request'. Enter your SQL command as it should be executed in the underlying database. e.g. if the db is Oracle, the statement should be entered as:
SELECT matnr,werks,lvorm,dispo
FROM marc
WHERE mandt = :a AND
matnr = :b AND
werks = :c
In the above :a, :b and :c are place holders for the actual comparison values. You dont have to enter those values. When you choose 'Explain' button, you will find the 'Execution Plan'. The important parameter which denotes the efficiency of the SQL statement is the 'Cost'. The cost should be as low as possible. The table access should be through INDEX UNIQUE SCAN. If you get a FULL TABLE SCAN and higher cost, you need to fine-tune your statement by modifying the where clause.
If you dont know Oracle SQL statements, execute the program in trace mode and go to the trace and you will find the underlying SQL statements issued to the database.

Execute A select statement under Oracle connection?

Hi,
How can i execute a select statement
under an existing Oracle connecton without
defining extera JDBC connection.

Be aware that you can create View Objects that are NOT based on entity objects. In this case, they are read only, but if you just want to display results, or check for a specific value, it at least reduces the overhead of an EO.
I'm not sure that answers the question here, but thought I would at least throw it out there.
In the View Object wizard, on the page that asks you to choose an EO, just click Next without selecting any EOs. This will automatically put you in expert query mode. Just type in your query and go.
You do have to be a little careful with expert mode queries, especially if you go back and edit them later. You need to make sure to keep the attribute mapping in synch on the Attribute page.
Also, I have found some limitations to this approach, which I'm not sure are fixed in 3.2. Namely, you can't use setWhereClause() to set the entire where clause string from the client. You have to use setWhereClauseParams(). This means that you have to have the basic where clause included in the query and user parameters as placeholders for the where clause values. These are JSP methods, I'm not sure what the equivalent is in DAC, but I am pretty sure the same limitation is there.

How to optimize this select statement its a simple select....

how to optimize this select statement as the records in earlier table is abt i million
and this simplet select statement is not executing and taking lot of time
SELECT guid
                stcts
INTO table gt_corcts
FROM   corcts
FOR all entries in gt_mege
WHERE /sapsll/corcts~stcts = gt_mege-ctsex
and /sapsll/corcts~guid_pobj = gt_Sagmeld-guid_pobj.
regards
Arora

Hi Arora,
Using Package size is very simple and you can avoid the time out and as well as the problem because of memory. Some time if you have too many records in the internal table, then you will get a short dump called TSV_TNEW_PAGE_ALLOC_FAILED.
Below is the sample code.
DATA p_size = 50000
SELECT field1 field2 field3
   INTO TABLE itab1 PACKAGE SIZE p_size
   FROM dtab
   WHERE <condition>
Other logic or process on the internal table itab1
FREE itab1.
ENDSELECT.
Here the only problem is you have to put the ENDSELECT.
How it works
In the first select it will select 50000 records ( or the p_size you gave). That will be in the internal table itab1.
In the second select it will clear the 50000 records already there and append next 50000 records from the database table.
So care should be taken to do all the logic or process with in select and endselect.
Some ABAP standards may not allow you to use select-endselect. But this is the best way to handle huge data without short dumps and memory related problems.
I am using this approach. My data is much more huge than yours. At an average of atleast 5 millions records per select.
Good luck and hope this help you.

How to execute dynamic if statement...

Hi All,
My PL/SQL Blocks looks like this
declare
i_string :='if 3>20 then 1 else 2 end if;' varchar2(100);
begin
end;
Between begin and end i want a piece of code which executes that if statement and sends 2 as output in dbms_output.put_line since 3 is not >20 .Basically i want to know how to execute dynamic if statement.Please help
Thanks,
Preethi

Hi,
i agree with Cyn. Dynamic SQL is often a bad idea. Try to avoid it.
Dynamic PL/SQL is even worse. If you really must do something dynamic, at least try to cast it as SQL rather than PL/SQL.
Does this do what you want?
CREATE OR REPLACE FUNCTION     eval_case
(     in_txt     IN     VARCHAR2
RETURN     NUMBER
DETERMINISTIC
IS
     return_val     NUMBER;
     sql_txt          VARCHAR2 (1000);
BEGIN
     sql_txt := 'SELECT CASE '
          ||           in_txt
          || '         END'
          || ' FROM dual';
     EXECUTE IMMEDIATE sql_txt INTO return_val;
     RETURN     return_val;
END     eval_case;
SHOW ERRORSYou might use the function above like this:
declare
     i_string varchar2(100) :='WHEN 3>20 THEN 1 ELSE 2';
begin
     dbms_output.put_line ( TO_CHAR (eval_case (i_string))
                    || ' = results of eval_case ('''
                    || i_string
                    || ''')'
end;

How to speed a select statement with the NOT EXISTS where condition ?

Hi all,
I created a view : create or replace view view_name as select * from table_1,table_2 where join_condition and some conditions.
Now I have added in the view "where" clause two NOT EXISTS conditions based on one another different table respectively.
Before I added these two conditions the response time was fast ; but after I added these two conditions then the response time deteriorated.
So how to optimize the select statement ? Hints and so on ...
Thank you very much indeed

Ree,
1. Find SSH client for windows, then execute SSH with Runtime.exec() on local host with arguments like remote host, auth, command to execute etc.
2. Get SSH client in Java and execute SSH commands on remote host using pure Java API.

Execute a unix shell script from forms9i

Hi ,
I would like to execute a unix shell script form a form when they pressed a button. The forms server is on Linux machine. I tried but when I pressed the button nothings happen. Could some one please help me how I could get working.
Is there is a way I could execute the unix shell script from PL/SQL proceudre or package.
Please some one help me.
Bain

You would not expect to see anything happening because the
script cannot directly send output to the web form. However, you can get it to write output to a file and use web.show_document in the form after the host command to display the file and see the output.

Error while trying to execute a unix shell script from java program

Hi
I have written a program to execute a unix shell script in a remote machine. I am using J2ssh libraries to estabilish the session connection with the remote box.The program is successfully able to connect and authenticate with the box.
The runtime .exec() is been implemented to execute the shell script.I have given below the code snippet.

System.out.println( "Connected to the server1" );
BufferedReader br = new BufferedReader(new InputStreamReader(p.getInputStream()));
String line = br.readLine();
while(line !=null)
System.out.println(line);

br.close();
p.getErrorStream ().close ();
p.getOutputStream().close();
int retVal = p.waitFor();
System.out.println("wait " + retVal);
