access报错，at address 1B0418EE in module 'msjet40.dll'


sql语句如下：
SELECT
COUNT(A.InfoID) AS InfoCount,
B.InfoTypeName
FROM T_Inforec A
LEFT JOIN T_InfoType B ON a.InfoTypeID=b.InfoTypeID
GROUP BY a.InfoTypeID,b.InfoTypeName

语句在access里查询可以通过，没有问题，在写在AdoQuery里时报以下错误：

Access violation at address 1B0418EE in module 'msjet40.dll'


Delphi6+Office2000

谢谢！

[解决办法]
在别的电脑上试试有没有问题?
