是的,
进入查询,而不是选择新的!选择使用向导设计的设计!
从菜单中选择查询 - >更新查询
添加要更新的表格
添加应更新的记录...
>
在行中更新以写入kdlsk如果kdlsk是你想要更新到你的领域的字符串
如果你想用其他字段类型的信息更新字段:[TheSourceField]其中TheSourceField是的名称带有信息的字段!
Yeah,
Go in Queries, than choose new one! Choose the design instaed using wizard!
From the menu choose query -> Update query
Add the table u want to update
Add the records that should be updated...
In the row Update to write "kdlsk" if kdlsk is the string that u want to update to your field
If u want to update a field with the information from other field type: [TheSourceField] Where TheSourceField is the name of the field with the information!
如果您只想这样做,那么PEB的回答可以帮助您轻松完成。
如果您想要语法然后按照PEB中的说明进行操作,然后选择View / SQL视图。看看那里的SQL代码,你会有一个例子。
否则帮助没有提到多个字段,但提供一般信息。
If you just want to do it, then PEB''s answer helps you to do it easily.
If you want the syntax then follow instructions in PEB''s then select View / SQL view. Look at the SQL code there and you will have an example.
Otherwise the Help doesn''t mention the multiple fields but give the general info.
