Mysql 正在努力解决错误1064

我已经尽力了，但没有得到下面的解决方案。。请帮忙

CREATE PROCEDURE AccountLedgerViewUnderBank()

begin


WITH GroupInMainGroup (accountGroupId,HierarchyLevel) AS
(
select accountGroupId,
1 as HierarchyLevel
from tbl_AccountGroup where accountGroupId='9'
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'
FROM tbl_AccountLedger

where accountGroupId IN (select accountGroupId from GroupInMainGroup
)
end ; //

错误显示

ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'Group InMainGroup (accountGroupId,HierarchyLevel) AS ( select accountGroupId, 1 a' at line 6 错误1064（42000）：您的SQL语法有错误；检查手册 对应于您的MySQL服务器版本，以便在“组”附近使用正确的语法 在单组（accountGroupId，HierarchyLevel）中作为 ( 选择accountGroupId， 6号线1 a'

看起来您正在尝试使用CTE，这是MySQL不支持的（在编写本文时）

大多数版本的MySQL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 ; //

MySQL不支持常用的表表达式。您需要升级到允许它们的DBMS。谢谢。但是您错过了；在第16行结束之前。+5到u
