更新查询 [英] Update query
问题描述
帮助，我想从表单运行更新查询..
并且很奇怪..
如果我想要更新查询可以运行更新手动输入的值
从表格（例如[Forms]！[frmUpdatePW]！[txtConfirmPW]）到表格
（tblPasswordMgmt.Password）
但是基于既不是两个值的标准。相反，它是（[表格]！[frmUpdatePW]！[txtusername] = tblPasswordMgmt.UserID）。
简而言之，
UPDATE tblPasswordMgmt
SET（Qn：命令SET是SET TO还是SET FROM？）
WHERE（Qn：可以命令WHERE被指定哪个与我想要更新的值无关？
？
查询可以拔出吗？从表单中更新
的值是否仅限于表中的特定字段？并且此特定字段
必须与用户输入的另一个值匹配，该值与表中另一个
字段匹配，然后更新表中的字段。
Thanxs Lotsa！

如果值是字符串，则需要将控制引用括在引号中。 （我使用Chr（34）
strSQL =" UPDATE tblPasswordMgmt" _
&" SET [SomeField] ="& Chr （34）& Me。[txtConfirmPW] .Value& Chr（34）&"" _
&" WHERE [UserID] ="& Chr（34） & Me.txtusername& Chr（34）&" ;;"
CurrentDB.Execute strSQL，dbFailOnError

应该是
strSQL =" UPDATE tblPasswordMgmt" _
&" SET [Password] ="& Chr（34 ）& Me。[txtConfirmPW] .Value& Chr（34）&"" _
&" WHERE [UserID] ="& Chr（34）& Me.txtusername& Chr（34）&" ;;"

它应该在一个模块中，还是可以在一个宏中，使用runSQL代码：
str SQL =" UPDATE tblPasswordMgmt" _
& SET [SomeField] =" &安培; Chr（34）&我。[txtConfirmPW] .Value& Chr（34）
& " " _
& WHERE [UserID] =" &安培; Chr（34）& Me.txtusername& Chr（34）& " ;;"
如果我将它放在查询中，它会提示输入无效的SQL
表达式
Help, i want to run an update query from a form..
and was wonderin..
Can the update query run if i want to update a value manually inputted
from a form (e.g. [Forms]![frmUpdatePW]![txtConfirmPW]) to a table
(tblPasswordMgmt.Password)
but based on a criteria which is neither the two values. Instead it''s
like ([Forms]![frmUpdatePW]![txtusername]=tblPasswordMgmt.UserID).
in a nutshell,
UPDATE tblPasswordMgmt
SET (Qn : The command SET is it SET TO or SET FROM?)
WHERE (Qn : Can the command WHERE be specified which has no relevance
to the value that i want to update?)
Can the query "plucked out" the value from the form to update
exclusively to a specific field in the table? and this specific field
must match another value input by the user which matches to another
field in the table before updating the field in the table.
Thanxs Lotsa!

If the values are strings you need to wrap the control refrerences in quotes. (I use Chr(34)
strSQL ="UPDATE tblPasswordMgmt " _
& "SET [SomeField]=" & Chr(34) & Me.[txtConfirmPW].Value & Chr(34) & " " _
& "WHERE [UserID]=" & Chr(34) & Me.txtusername & Chr(34) & ";"

Should be
strSQL ="UPDATE tblPasswordMgmt " _
& "SET [Password]=" & Chr(34) & Me.[txtConfirmPW].Value & Chr(34) & " " _
& "WHERE [UserID]=" & Chr(34) & Me.txtusername & Chr(34) & ";"

Hi, should it be in a module or can it be in a macro, with runSQL code:
strSQL ="UPDATE tblPasswordMgmt " _
& "SET [SomeField]=" & Chr(34) & Me.[txtConfirmPW].Value & Chr(34)
& " " _
& "WHERE [UserID]=" & Chr(34) & Me.txtusername & Chr(34) & ";"
And if i were to place it in a query, it prompts for an invalid SQL
expression
