This Query is much slow when i used same table twice in left join.

select A.codeNumber,A.englishName from (ledgerGroupList as A LEFT JOIN 
ledgerGroupList as ledgerGroupNoCList ON 
A.ledgerGroupNoC=ledgerGroupNoCList.nameNo) where ((A.lft 
>ledgerGroupNoCList.lft and A.rgt<ledgerGroupNoCList.rgt) and 
ledgerGroupNoCList.englishName='Cash In Hands') or ((A.lft 
>ledgerGroupNoCList.lft and A.rgt<ledgerGroupNoCList.rgt) and 
ledgerGroupNoCList.englishName='Bank Accounts') and A.type1='L' order by 
A.englishName 

Please give me proper solution.
