the stored procedure is :
CREATE OR REPLACE FUNCTION update_exam_modality(bigint, varchar(16)) RETURNS text AS'
DECLARE
mod_of_study varchar(16);
mod_pattern varchar(16);
pos int;
BEGIN
pos := -1;
select into mod_of_study trim(mod_in_exam) from exam where exam_id = $1;
if (mod_of_study is NULL)
then
update exam set mod_in_exam = $2 where exam_id =$1;
else
pos := strpos(mod_of_study, trim($2));
if( pos != 0 )
then
RETURN ''no_change'';
else
mod_pattern := mod_of_study || '\\' || $2;
update exam set mod_in_exam = mod_pattern where exam_id =$1;
end if;
end if;
RETURN ''done'';
END;
'LANGUAGE 'plpgsql';
and when i run
\i temsql
i get the following error:
