Hi,
We want to run some SQL Scripts from forms 6i.
We are using a form’s host command in order to that but not successful.
For Example:
…………………………
output:='c:\run_sql.txt '||un||'/'||pw||'@'||cn ;
Host(output,no_screen);
The run_sql.txt contains the following :
set trimspool on
set heading off
set feedback off
set echo off
spool c:\traceonly.txt
set autotrace traceonly
select * from scott.emp ;
spool off
set autotrace off
Please let us inform how should we run the above script from forms 6i’s Host Command?

Hi,
As you said we put the sqlplus with the username and password in the output variable like that:
output:='sqlplus Rami/Ramo@Dento @C:\run_sql.txt' ;
But after openeing the database session for running the scripts from forms6i, forms 6i hangs and closed the database session.
Why this happened.
We have oracle database 10 G.

Hi,
Now The sql scripts from forms 6i against 10G database are running fine.
But why this Ora-00904 error comes along with the scripts results on forms 6i screen. You can see it below
Below you find the complete code which I am using on WBPT.
If you have suggestion about improving this code please let me know. I am a single person whoc is doing this.
Your suggestion will be appreciated.
Thanks

Following result was generate on forms screen with ORA-00904: "POSITION" error

Hi,
Actually we are trying to generate autotrace plan of a sql statement on forms screen.
In order to do that I type the sql on forms screen1 and then press the button "Generate Autotrace" in which all the code is written which I posted earlier.
FOr example: I type the following SQL on screen 1:
Select * from scott.emp
I also like to inform you that I am using another procedure "ALERT1" which invokes when I press the OK button of alert message. This alert comes with OK and CANCEL button after pressing the first "Generate Autotrace" button.
The alert message invoke with OK and CANCEL Button.The OK button invoke the procedure "Alert1" which then generate the results on forms screen2. Earlier when I run the forms 6i against 8i database I didn't get this error, which now comes along with the autotrace results on forms screen2 in database 10G.
Below is the autotrace trace result starting with error:
I will very much apprecaite your suggestion that how to get rid of this error as well as please look at my code which I posted earlier as well as the procedure "ALERT1" which you can see below, should I improve it:
Insbor
The result genrates with error:
ERROR:

IF button_pressed = alert_button1 THEN

output := 'cscript c:\explain_plus\misc\sleep1.vbs';
Host(output,

in_file := text_io.Fopen('c:\explain_plus\misc\traceonly.txt',

LOOP
text_io.Get_line(in_file,
linebuf);
:sql.execution_plan := :sql.execution_plan || linebuf || Chr(10);
END LOOP;
text_io.Fclose(in_file);

Hi David,
I am not a pefect prograamer or user of forms 6i. I am a free lance certified DBA who is working on this small forms applicaton.
Before start working on my application I got suggestion from someone who recomended me to use text_io ( a forms utility) for reading and writing a text file through forms. I read forms help about text_io, from where I got it in my little application.
Is not a good option, please give me a good example of utl_file using my code, which can be helpful for me to replace utl_file with text_io.
As you said that output lines are longer than 80 chararacters can be written out using the default 'text_io.Fopen' statement, could you explain it?
REgarding the error It might be a missing column name thats why the result generate with error.
David please send me a good example of UTl_File using my code which I posted earlier.
I will be thankful to you. May GOD bless on you.

have you determined on which line the error is being raised? This one is important.

Put an alert between each line to help you determine which line is failing.

I don't have good documentation for the 'text_io.Fopen' so I can't tell you exactly how to handle lines longer than 'xxx' characters. I don't even know what the default 'xxx' value IS!! Search this forum for 'text_io', there are plenty of examples. Also try googling it. Are you getting all the text coming out in your output files? If so, then the default line width is not the problem. Experiment, try putting out an 80 character line, then a 100, then a 150, then a 200. If they all work, then the line width is not the problem.
So put that alert between each line and FIND OUT WHICH IS FAILING.
Anyway, work out EXACTLY which line is causing the error and get back to us with it.
David

David,
Thanks for your reply.
Regarding putting alert b/w each line in oredr to determine which line is falling, could you please give an example of that alert.
Quote:

Put alert b/w each lines, does it means I put the alert in each line of my ALERT1 procedure?
Thanks

Hi David,
Now my application of getting explain plan of a sql is running fine.
But during running, one script which is written inside the wbp trigger, I manually get rid of the forms plus80.sql screen, which is cumbersome. Could someone suggest me what changes I will do in the code in order to terminate this plus80.sql forms screen automatically.
Thanks
Insbor.
My code as I posted earlier
Declare
in_file Text_IO.File_Type;
linebuf VARCHAR2(1800);
output varchar2(1000);

un VARCHAR2(80);
pw VARCHAR2(80);

Hi David,
In my code as I posted I didnt use close_form or exit_form command.
Regarding the problem Should I use these commands in my code, if Yes where should I place this command, so the plus80.sql window will be automatically closed after performing the operation.
Thanks
Insbor
