I'm trying to build a function that returns a table with the elements of a cursor...
But how can I initialiez this table ? I do not know how many rows there will be....
tab ttab := ttab(tobj(null,null)) ; i can insert 1 row
tab ttab := ttab() ; i can't insert any row
any help appreciated
create or relace type tobj as object(cle number, nom varchar2(128));
create or replace type ttab is table of tobj;
CREATE OR REPLACE FUNCTION testfunc Return ttab IS
cursor CUR is select ARTICLE_CLE, ARTICLE_LIBELLE from ARTICLES where TVA_CLE=2;
tab ttab := ttab(tobj(null,null)) ;
i integer :=0;
BEGIN
for CUR_VAL in CUR loop
tab(i).cle := CUR_VAL.ARTICLE_CLE;
tab(i).nom := CUR_VAL.ARTICLE_LIBELLE;
i:=i+1;
end loop;
close CUR;
RETURN tab;
END testfunc;
