 insert into abc (mkey,mident) values (2,"b")
 insert into abc (mkey,mident) values (3,"c")

 create cursor def (mkey_fk i,mtext c(10))
 insert into def (mkey_fk,mtext) values  (1,"inf1")
 insert into def  (mkey_fk,mtext)  values (1,"inf2")
 insert into def  (mkey_fk,mtext)  values (2,"infA")

 insert into def  (mkey_fk,mtext)  values (3,"to_del")
 insert into def  (mkey_fk,mtext)  values (4,"to_del")
SELECT * FROM abc JOIN def ON  abc.mkey=def.mkey_fk INTO cursor ghi
