As I am converting from Sybase I wanted to= create a=20 function which would replicate the behaviour of the sybase "Locate"=20 command.

The goal is to have

locate( stra, strb) =3D position(strb in= =20 stra)

where "position" is the standard postgres = function=20 for the index position of string "A" in string "B"

My attempt at a function to do this task r= eturns=20 the error message

ERROR: parse error at or near '"' &nb= sp; =20

I can not see why.... and have attached th= e simple=20 function.

------------------------------------------------------------------= ------------------------------------

CREATE OR REPLACE FUNCTION public.locate(b= pchar,=20 bpchar)
RETURNS int4 AS
'

-- search for the position of $2 in= =20 $1

declare
srcs= tr alias=20 for $1;
searchstr alias for $2;

begin
return position(searchstr in=20 srcstr);
'
LANGUAGE 'plpgsql' VOLATILE;

Thanks very much
