Question

我想在数据库Project.mdb中成功地在一个表中插入记录，但在更新记录时它会显示＆＃34; No Record Found＆＃34;。 Access中的表包含以下字段PNR - FNAME - LNAME - SOURCE - DEST - DOJ - NOP 下面的代码没有显示任何错误，但它直接跳转到最后一个语句而不更新或检查值。请帮助。

您所拥有的代码不会更新记录，只是尝试阅读它们。但是，您将始终拥有一个空记录集，因为读取书表内容的SQL语句不是有效的。这需要遵循：

objRS.Open＆＃34; select * from Book＆＃34;，objConn
