    Hi

    I have the following shell script

    #####################################
    #!/bin/sh

    user =${1}
    pass =${2}
    sid =${3}
    colmatch =${4}
    deltable =${5}
    childtbl =${6}
    childcol =${7}
    parenttbl =${8}
    parentcol =${9}
    part =${10}



    ${ORACLE_HOME}/bin/sqlplus ${user}@${sid}/${pass} << __eof__
    set head off;
    commit;
    set transaction use rollback segment rei_data_load;
    declare
    acc_num ${deltable}.${colmatch}%type;
    cursor c1 is
    select ${colmatch} from ${deltable};
    begin
    open c1;
    loop
    fetch c1 into acc_num ;
    exit when c1%notfound;
    Delete from ${childtbl} partition ${part}
    where ${childcol} = acc_num;
    Delete from ${parenttbl} partition ${part}
    where ${parentcol} = acc_num;
    end loop;
    close c1;
    end;

    #######################################

    How do I run it from unix and test it out. The program name is del.sh

    Please advise

    Running it as

    /bin/sh your_script_name

    or

    ./your_script_name

    Either of then would work on borne shell/korne shell

    if your are in c shell

    % $ <-- this would take you to korne shell

    $ /bin/sh your_script_name

    make sure that read and execute permissions had been set.

    you are correct, the syntax is:

    ./del.sh par1 par2 par3....

    In the above example, I am trying to pass the username,passwd and sid as follows.(For timebeing I have suppressed the other parameters)

    ./del1.sh rei nas rel (user=rei, pass=nas , sid =rel)
    and
    ./del1.sh rei rel nas.

    In both the cases, I am not getting connected.

    If you are planning to execute the shell script directly, then it would be
    ./del.sh par1 par2 ...

    If you are calling it from another shell script, you can call it as

    /fullpath/del.sh par1 par2 par3

    IF you are planning to call it from another script then, it would be good to rename your del.sh to dell_data or delpartition or something like this order with no extension.

    /fullpath/del par1 par2 par3

    If you are passing the parameters

    par1 = xyd
    par2 = 623
    par3= 234

    /fullpath/del $par1 $par2 $par3 ...

    Do not use the
    /fullpath/del par1 par2 par3 for the above example, because you would just end up passing names par1 par2 and par3 and not the values that you assigned to them.

    Hope this would help you.

    IT was because that you are not passing the temination point for your script

    i.e __eof__ .

    add the following to the end of your posted script

    /
    __eof__


    Also change the following
    ${ORACLE_HOME}/bin/sqlplus ${user}@${sid}/${pass}

    to
    ${ORACLE_HOME}/bin/sqlplus ${user}/${pass}@${sid}

    Hope this would fix the problem.

    I have simplified the code,, only to accept the user name.

    Please let me know I do I pass only one parameter

    <>>>>
    #!/bin/sh

    user = ${1}

    ${ORACLE_HOME}/bin/sqlplus ${user}/nas@rel << __eof__
    set head off;
    commit;
    set serveroutput on;
    select to_char(sysdate,'DD-MON-YY HH:MI:SS') from dual;
    __eof__


    *********************************************
    running it as ./del3.sh rei fails
