Hello
I need to transfer a db form one to another server. I wanted to do this
with pg_dumpall and psql -e ....
I isolated the problem in a view. When I call a self defined function
(buildstring) the problem occurs and when I remove this call pg_dumpall
works. Calling the view with select * from viewrzumfang works with and
without the function call.
I use postgresql 7.0 on SUSE Linux
Function :
CREATE FUNCTION buildString(bpchar) RETURNS text AS '
DECLARE
list text;
rec record;
BEGIN
list := '''';
FOR rec IN SELECT z_u_umfang FROM zylinder_umfang WHERE z_u_typ
= $1;
list := list || text(rec.z_u_umfang) || '','';
END LOOP;
RETURN list;
END;
' LANGUAGE 'plpgsql';
View that is not working :
SELECT rotation.r_code, rotation.r_name, rotation.r_z_typ,
(SELECT zylinder_typen.z_laenge FROM zylinder_typen WHERE
(zylinder_typen.z_typ = rotation.r_z_typ)) AS r_z_laenge,
(SELECT zylinder_typen.z_blaenge FROM zylinder_typen WHERE
(zylinder_typen.z_typ = rotation.r_z_typ)) AS r_z_blaenge,
(SELECT zylinder_typen.z_alaenge_l FROM zylinder_typen WHERE
(zylinder_typen.z_typ = rotation.r_z_typ)) AS r_z_alaenge_l,
(SELECT zylinder_typen.z_alaenge_r FROM zylinder_typen WHERE
(zylinder_typen.z_typ = rotation.r_z_typ)) AS r_z_alaenge_r,
(SELECT rtrim(buildstring(rotation.r_z_typ), ','::text) AS rtrim) AS
r_z_umfang FROM rotation;
View that is working :
SELECT rotation.r_code, rotation.r_name, rotation.r_z_typ,
(SELECT zylinder_typen.z_laenge FROM zylinder_typen WHERE
(zylinder_typen.z_typ = rotation.r_z_typ)) AS r_z_laenge,
(SELECT zylinder_typen.z_blaenge FROM zylinder_typen WHERE
(zylinder_typen.z_typ = rotation.r_z_typ)) AS r_z_blaenge,
(SELECT zylinder_typen.z_alaenge_l FROM zylinder_typen WHERE
(zylinder_typen.z_typ = rotation.r_z_typ)) AS r_z_alaenge_l,
(SELECT zylinder_typen.z_alaenge_r FROM zylinder_typen WHERE
(zylinder_typen.z_typ = rotation.r_z_typ)) AS r_z_alaenge_r,
FROM rotation;
Thanks for any help ... jr
