Answer 1

It looks like you're trying to use a CTE, which is not supported with MySQL (at time of writing).
Subqueries are supported with most versions of MySQL, so you may be able to rewrite it as something like:
CREATE PROCEDURE AccountLedgerViewUnderBank()
begin
SELECT ledgerId AS 'Account Ledger Id',
acccountLedgerName AS 'Account Ledger Name'
FROM tbl_AccountLedger
where accountGroupId
IN (select accountGroupId
from tbl_AccountGroup where accountGroupId='9'
UNION ALL
select e.accountGroupId
from tbl_AccountGroup as e,GroupInMainGroup G
where e.groupUnder=G.accountGroupId)
end ; //
