问题
I know this is probably a simple thing I'm missing, but I'm hoping you all can help. I'm trying to add a textbox to my form that allows users to type in search criteria and have the query filter the records to only display those that qualify. The trick is I want the user to be able to type in info and have it check all the fields of the form and return records for any that are valid.
I set up a query with the fields that I want checked and I watched a few tutorials on setting criteria, but they are all working with multiple search bars. Is there a way to do it with only 1?
Like "*" Or [Forms]![Publications Page]![FilterBox] OR "*"
This is the criteria expression I wrote. It returns records just not the ones I want and doesn't seem to change after I change what is in [FilterBox]. I have 4 fields I'm running this same criteria on. All thoughts and suggestions are greatly appreciated!
Thanks!
回答1:
The resulting criteria should be something like
[LastName] Like '*searchtext*' Or [FirstName] Like '*searchtext*' Or ...
So, you would have to set up a single criteria like this
Dim crit As String
crit = " Like '*" & Replace(Me!FilterBox, "'", "''") & "*' "
where the replace statement replces single (') by 2. This enables the user to enter an apostrophe in the search box.
Now you must create the whole criteria
crit = "[Field1]" & crit & "Or [Field2]" & crit & "Or [Field3]" & crit & "Or [Field4]" & crit
