MySql中CTE的替代方案

我在TSQL中有创建树的代码，但我很困惑：如何将其转换为mysql

CREATE PROCEDURE AccountLedgerViewUnderSundryDebtorCreditorCash  

AS  


WITH GroupInMainGroup (accountGroupId,HierarchyLevel) AS  
(  
select accountGroupId,  
1 as HierarchyLevel  
from tbl_AccountGroup where accountGroupId='27'or accountGroupId = '28'or accountGroupId = '11'  
UNION ALL  
select e.accountGroupId,  
G.HierarchyLevel + 1 AS HierarchyLevel  
from tbl_AccountGroup as e,GroupInMainGroup G  
where e.groupUnder=G.accountGroupId  
)  




SELECT  
ledgerId AS [Account Ledger Id],  
acccountLedgerName AS [Account Ledger Name],  
accountGroupId AS [Account Group Id],  
openingBalance AS [Opening Balance],  
debitOrCredit AS [Credit Or Debit],  
defaultOrNot AS [Editable Or Not],  
description AS [Description]  


FROM tbl_AccountLedger  
where accountGroupId IN (select accountGroupId from GroupInMainGroup)

MySQL的可能副本无法执行递归查询。您需要编写一个递归调用自身的存储过程
