Declare cursor problem
Hey,

Recently I’m using Firebird, great database only little in documentation. At the moment I’m using the IB 6.0 documentation from the firebird site, only I think these are outdated? Some statements just don’t seem to work in Firebird 1.5, like some of the stored procedures I’ve found in these books. For example: “Set Term ^;” and more important I don’t seem to get cursor statements working in Firebird (not even when using the same example)

Could someone tell me what I’m doing wrong?

Hesder


For example a cursor statement I’ve tried to convert from oracle to Firebird 1.5 :

CREATE PROCEDURE get_records_10monsteroverzicht(
session_id VARCHAR(25),
group_name VARCHAR(25),
date_from VARCHAR(25)
) AS


BEGIN

declare c_template CURSOR for
select tmplt_name
from ip_smpl_grp_DETAIL
where smpl_grp_name = group_name
ORDER BY tmplt_name;

...how to use cursor in firebird?...

END

SET TERM is only used by client tools. What are you using to connect and run your scripts?

Firebird doesn't support a CURSOR, it does support cycling through resultsets via a FOR SELECT construct:

FOR SELECT tmplt_name
from ip_smpl_grp_DETAIL
where smpl_grp_name = group_name
ORDER BY tmplt_name
INTO :variable_name
DO ... loop ...
