Oracle 12c - Issue in PL/SQL -


i have following block of code:

declare   cursor c_cursor     select *       table_a;      in c_cursor loop     if i.id not in (select id table_b ind_val='y')            begin         insert val_table_err         values (''error:id''|| i.id,                 1,                 1,                 null,                 1,                 i.type_cd);       end;     end if;     end loop;

i getting error pls-00405: subquery not allowed in context

any resolve issue appreciated.

you can't not in in version of oracle.

it make sense put not in clause cursor definition. assuming not in rather not exists more efficient approach, work.

cursor c_cursor     select *       table_a      a.id not in (select b.id                           table_b b                          ind_val = 'y');

if want check done within loop, you'd need different construction. like

for in c_cursor  loop   select count(*)      l_cnt     table_b b    b.id = i.id      , b.ind_val = 'y';    if( l_cnt = 0 )       <<do something>>   end if; end loop;

of course, won't efficient or clear filtering out loans in cursor in first place.

java - How to specify maven bin in eclipse maven plugin? -

i have eclipse maven plugin coming on centos. how can execute maven command on linx like: mvn clean package [abigail@localhost ~]$ mvn bash: mvn: command not found how should specify path executable of maven plugin in eclipse? or have install maven seperately？ thanks. eclipse (m2e) have bundled central parts of maven inside eclipse plugin, why not detected, , not usable. investigation find correct way bootstrap it, have create launcher file manually. if want run maven outside of eclipse, far better off standalone version of maven. mvn command bootstrap maven runtime system correctly, , secondly, able use advice concerning use of maven. maven binaries quite stable, wouldn't need upgrade upgrade eclipse. you can subsequently switch eclipse use external installation if prefer.
