Hi,

INTO NewTable
FROM ExistingTable
在哪里......
SELECT (Trim(LName) & '' '' & Trim(FName) & '' '' & Trim(MName)) AS FullName
INTO NewTable
FROM ExistingTable
WHERE ...
但为什么要这么麻烦？标准化系统会谨慎地存储名称
并在运行时在查询中连接。

多年前SELECT（修剪（LName）&''''& ;修剪（FName）&''''&'修剪（MName））
可能会导致两个空格在某些情况下字段为空或保持
a零长度字符串。我不知道是否已经是这种情况了，但是这里已经多次讨论过
解决方案，如下所述：
http://groups.google.ca/group/comp.d...07ea4bc514ad10
其中Arvin写道：
"尝试：
= [Street1 ]& （"，" + [Street2]）& （"，+ [Town]）& （"，" + [县]）&
（"，
" + [PostCode]）
+运算符不会与null连接，而&运算符不会与null连接。将来。
无论如何，我和基思在一起想知道这张桌子是否是原来的海报作为你的查询的第一部分是否真的需要
br />
给出了新表格给出的所有内容。
Years ago SELECT (Trim(LName) & '' '' & Trim(FName) & '' '' & Trim(MName))
might result in two spaces in some cases where a field was null or held
a zero length string. I don''t know if that is the case anymore but a
solution has been discussed many times here as in:
http://groups.google.ca/group/comp.d...07ea4bc514ad10
where Arvin writes:
"Try:
=[Street1] & (", " + [Street2]) & (", " + [Town]) & (", " + [County]) &
(",
" + [PostCode])
The "+" operator will not concatenate with a null, while the "&" will."
Regardless, I am with Keith in wondering if creatig this table is
REALLY necessaryfor the original poster as the first part of your query
gives all that the new table gives.
