更新查询帮助 [英] Update query help
问题描述
我将记录导入到一个表中，后来发现其中许多记录在其中一个字段中有* b $ b尾随空格。如果我早点抓住它，我可以在导入之前修剪空格。
这不会工作（没有改变）：
UPDATE tblManuals SET tblManuals.PARTNUM = Trim（[partnum]）;
有人请告诉我如何更新查询以修剪
空格？
I imported records into a table, later found out that many of them had
trailing spaces in one of the fields. If I''d caught it sooner, I could have
trimmed the spaces before the import.
This wouldn''t work (nothing changed):
UPDATE tblManuals SET tblManuals.PARTNUM = Trim([partnum]);
Would someone please tell me how to do an update query that will trim the
spaces?

Randy,
Create a new field in your query and enter this expression:
MyUpdateField:Trim([partnum])
Then change the query to an Update Query and enter this expression where it says
Update To in the PartNum field:
MyUpDateField

Perfect. Should have thought of that myself. Thanks!

好吧，我说得太早了。我还有问题。尽管Trim函数在A2K查询网格中工作，但它看起来并不像
。没错，他们只是
不要修剪空间。我尝试了MyUpdateField：Trim（[partnum]）作为
更新查询，MakeTable查询和Select查询。修剪简单
不起作用。令人惊讶。
Well, I spoke a bit too soon. I still have a problem. It doesn''t look as
though the Trim functions work in the A2K query grid. No error, they just
don''t trim the spaces. I tried the MyUpdateField:Trim([partnum]) as an
Update query, a MakeTable query and as a Select query. Trim just plain
doesn''t work. Surprising.
