看起来你正在尝试使用CTE，而MySQL不支持（在撰写本文时）。

大多数MySQL版本都支持子查询，因此您可以将其重写为：

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 ; //
