这是连接配置。 DB = Sequel.ado（：conn_string => \'Provider = Microsoft.ACE.OLEDB.12.0;数据源= C：\\ ContractManagement1.accdb \'） 这是迁移步骤。所有这些都在Postgresql 8.4上传递。

解决方法

这已在Sequel的master分支中修复，版本3.24.0（将在下周发布）将具有错误修复。     ,我认为您收到此错误消息... 
OLE error code:80040E14 in Microsoft Office Access Database Engine
     Syntax error (missing operator) in query expression \'LIMIT 1 1\'.
...因为Access SQL不支持LIMIT。请参阅对相关的堆栈溢出问题的答复。 查看是否可以使用Access SQL TOP N替代LIMITN。 
SELECT TOP 1 m.id,m.paid_in_full,m.date_field
FROM MyTable AS m
ORDER BY m.date_field DESC;
