Passing a String with special character as an input
Hi -
This is related to my earlier post. For the function I am passing
a string. But the string some time has a single quote inside the string like
"IT's a String Test" , How can I handle that, can you please help?
CREATE OR REPLACE FUNCTION test_repl(x character varying)
RETURNS character varying AS
$BODY$
DECLARE
ret_var varchar(4000);
a record;
begin
ret_var := x;
for a in select * from lookup
loop
ret_var := replace(ret_var,a.code,a.codeword);
end loop;
return ret_var;
END;
$BODY$
LANGUAGE 'plpgsql' VOLATILE
COST 100;
ALTER FUNCTION test_repl(character varying) OWNER TO postgres;

on stored procedure level you can do nothing
in SQL level, you have to duble quotes
like INSERT INTO data VALUES('Peter''s book');

at the SQL level, pass it as a parameter.
like, in perl...
my $sth = $dbh->prepare('select test_repl(?);');
$sth->execute("It's a String Test");
(or my $sth->execute('It\'s a String Test'); ...)
