I am no expert in things SQL, so i am not sure if this SQL-script does what i think it does or something different:

As i read it your stored procedure sets a certain variable to the value "1". In Korn shell, when you assign a variable with a process' outcome like in:

Code:
var=$( command )

then the variable is assigned with the output of the command, not its variables. So, if your stored procedure only changes the variables value but has no output, then the ksh-variable will be empty - as the output is empty.

I hope this helps.

NAME
shift - shell built-in function to traverse either a shell's argument list or a list of field-separated words SYNOPSIS
sh shift [n] csh shift [variable] ksh * shift [n] DESCRIPTION
sh The positional parameters from $n+1 ... are renamed $1 ... . If n is not given, it is assumed to be 1. csh The components of argv, or variable, if supplied, are shifted to the left, discarding the first component. It is an error for the variable not to be set or to have a null value. ksh The positional parameters from $n+1 $n+1 ... are renamed $1 ..., default n is 1. The parameter n can be any arithmetic expression that evaluates to a non-negative number less than or equal to $#. On this man page, ksh(1) commands that are preceded by one or two * (asterisks) are treated specially in the following ways: 1. Variable assignment lists preceding the command remain in effect when the command completes. 2. I/O redirections are processed after variable assignments. 3. Errors cause a script that contains them to abort. 4. Words, following a command preceded by ** that are in the format of a variable assignment, are expanded with the same rules as a vari- able assignment. This means that tilde substitution is performed after the = sign and word splitting and file name generation are not performed. ATTRIBUTES
