Hi Team,

I have one requirement as part automation. i have declared some variable at unix level in shell script. i want to use variable values in SQL command and PL/SQL blocks. for eg

code:

export owner=`echo $line|cut -d':' -f1`
export tname=`echo $line|cut -d':' -f2`
echo $owner
echo $tname
sqlplus -s '/as sysdba' $owner $tname<<EOF >abc.log
DECLARE

v_owner varchar2(15) := '$1';
v_tname varchar2(25) := '$2';

BEGIN
dbms_output.put_line('Value of Table Name:'||v_tname);
dbms_output.put_line('Value of Table Owner:'||v_owner);
end;
EOF


Please help me on this. how we can use variable inside pl/sql block.

thanks

Please read How to use [code] tags and make your code easier to read.
Indent the code.

Try this
sqlplus -s '/as sysdba' <<EOF >abc.log
DECLARE

v_owner varchar2(15) := '$owner';
v_tname varchar2(25) := '$tname';

BEGIN
  dbms_output.put_line('Value of Table Name:'||v_tname);
  dbms_output.put_line('Value of Table Owner:'||v_owner);
end;
EOF

Hi Michel,

It's not working.

below is the full code that i have written for automation. I am reading input from a file that store list of table and its owner.

And i am checking the variable that is declared in unix level inside SQL and PL/SQL block.



#!/bin/ksh
while read line; do
owner=`echo $line|cut -d':' -f1`
tname=`echo $line|cut -d':' -f2`
  echo $owner
  echo $tname
sqlplus -s '/as sysdba'<<EOF >defrag.log
set serveroutput on
set echo on
set feedback on
select owner from dba_tables where table_name='$tname';
DECLARE
v_owner varchar2(15) := '$owner';
v_tname varchar2(25) := '$tname';

BEGIN
dbms_output.put_line('Value of Table Name:'||v_tname);
dbms_output.put_line('Value of Table Owner:'||v_owner);
end;
EOF
done < table_list.txt



on Unix prompt it is displaying values that is stored in $owner and $tname but in abc.log file it is showing below output

no rows selected

and at Unix Prompt

ABC
Table1
ABC
Table2
ABC
Table3

You removed "export" so it can't work.

Michel,

I changed the code with export but it is not working. the result is same as above.



#!/bin/ksh
while read line; do
export owner=`echo $line|cut -d':' -f1`
export tname=`echo $line|cut -d':' -f2`
  echo $owner
  echo $tname
sqlplus -s '/as sysdba' <<EOF >defrag.log
set serverout on
set echo on
set feedback on
select owner from dba_tables where table_name='$tname';
DECLARE
v_owner varchar2(15) := '$owner';
v_tname varchar2(25) := '$tname';
BEGIN
dbms_output.put_line('Value of Table Name:'||v_tname);
dbms_output.put_line('Value of Table Owner:'||v_owner);
end;
EOF
done < table_list.txt




and regarding Unix prompt output, all output showing in capital letter. its my typing mistake.

Copy and paste your session, I am not behind your shoulders to see what happens on your screen.
Remove ">defrag.log" and add "cat table_list.txt'.

Something wrong in your session.
You should have some messages starting with "Value of Table ".

Ok I see.
The PL/SQL block should end with a "/" alone in a line otherwise it is not executed.
