This error is often caused by variables defined with the same names as 
table columns.

Anyway it would be easier for us if you write source of line which 
caused error.

Hi,
 
I am using 7.1.3 on RedHat Linux 7.2.
 
I try to create a trigger on the table, I wrote a function in plpgsql,
which always fail on this sql command:
 
select (''UPD'' || int2hex(nextval(''updid''), 8)) as v_updid;
 
The function is like this:
 
begin
            select (''UPD'' || int2hex(nextval(''updid''), 8)) as
v_updid;
            if not found then
                 raise exception ''Unable to get updid.'';
            end if;
        end;
 
It give me this error when I trigger the function: 
 
NOTICE:  Error occurred while executing PL/pgSQL function
pg_fct_bf_ins_inf_article
NOTICE:  line 9 at SQL statement   -- the SQL select command
ERROR:  parser: parse error at or near "$1"
 
I can execute the SQL without problem. 
<<
select ('UPD' || int2hex(nextval('updid'), 8)) as v_updid;
>>
 
Can anyone help me to see what is the problem here.
 
Li Hao

Did you mean:

select into v_updid ''UPD'' || int2hex(nextval(''updid''), 8);
?

Hi,

Here is the source:

CREATE OR REPLACE FUNCTION pg_fct_bf_ins_inf_article () RETURNS OPAQUE
AS '
DECLARE
   v_language   sys_codetable.id%type;
   v_updtype    sys_codetable.id%type;
   v_updid      varchar(12);
   v_articleurl varchar(60);
Begin

        begin
            select (''UPD'' || int2hex(nextval(''updid''), 8)) as
v_updid;
            if not found then
                 raise exception ''Unable to get updid.'';
            end if;
        end;

        begin
            select coalesce(id,1)
            into   v_language
            from   sys_codetable
            where  valueen = ''ENGLISH'' and fieldname = ''LANGUAGE'' ;
            if not found then
                 raise exception ''Unable to get language.'';
            end if;
        end;

        begin
            select coalesce(id,1)
            into   v_updtype
            from   sys_codetable
            where  valueen = ''ARTICLE'' and fieldname = ''UPDTYPE'' ;
            if not found then
                 raise exception ''Unable to get updtype.'';
            end if;
        end;

        begin
            select value into v_articleurl
            from sys_parameter
            where key = ''ARTICLEURL'';
            if not found then
                 raise exception ''Unable to get articleurl.'';
            end if;
        end;

        begin
                insert into inf_update
                ( UPDID,
                  UPDTYPE,
                  RECCREATEON,
                  RECCREATEBY,
                  CONTENT,
                  LINK,
                  DISPLAY,
                  LANGUAGE ) values
                ( v_updid,
                  v_updtype,
                  now(),
                  new.reccreateby,
                  new.title ,
                  new.link,
                  ''Y'',
                  v_language );
            if not found then
                 raise exception ''Unable to insert record to
inf_update.'';
            end if;
        end;
End;

' LANGUAGE 'plpgsql';

CREATE TRIGGER bf_ins_inf_article
        BEFORE INSERT ON inf_article FOR EACH ROW
        EXECUTE PROCEDURE pg_fct_bf_ins_inf_article();

So the Line 9 is this line:
            select (''UPD'' || int2hex(nextval(''updid''), 8)) as
v_updid;

The table column name is updid, so I define the variable as v_updid,
which should not conflict with the table column name.

Hi,

What I try to get is 

venus=# select ('UPD' || int2hex(nextval('updid'), 8)) as v_updid;
   v_updid   
-------------
 UPD0000145C
(1 row)
updid is a sequence. I am try to generate a index with character and
sequence number.

Anyway, I solve it by change the script to :

select (''UPD'' || int2hex(nextval(''updid''), 8)) into v_updid;

Thank you.

Li Hao

Did you mean:

select into v_updid ''UPD'' || int2hex(nextval(''updid''), 8);
?
