pass null value to sql script from korn shell script
Post 302571954 by megha2525 on Tuesday 8th of November 2011 04:56:46 PM

Code:
sqlplus -s /nolog @$sqlfile "${1-NULL}" $2 $3 $4I passed in values for $2 $3 $4.
whenever $1 $2 $3 $4 are passed from shell to sqlplus they are referred to as &1 &2 &3 &4 .
now we know that I passed no value for $1 ,
but in sql script what is happening is the first non null value that is from shell i.e, $2 in our case now ... is being treated as &1 .
so its not working

Do u know how can I display the values passed from korn shell in the sql script?
for eg in the korn shell i am passing a value like this.
Code:
sqlplus -s /nolog @sqlpfile $1 in the sql script i am doing this. declare var1 varchar2(50); begin var1='&1'; dbms_output.put_line(var1); end;
PLS-00103: Encountered the symbol "=" when expecting one of the following:
:= . ( @ % ;
The symbol ":= was inserted before "=" to continue.
not sure whats going on
