Hi experts,
I have a database that have these 2 fields, name and firstname, and I want to do a query from one field that MIGHT INCLUDE both fields or JUST ONE
EX.
     Name                         FirstName
1   John                            Doe
2   George Wayne
3   John Doe
4   George                        Wayne

I would like to search for John, and get record 1 and 3
Search John Doe and get record 1 and 3
Search Doe and get record 1 and 3

What I am able to do with the code below is : If I search John Doe, I will only get record 3, but I want to be able to get record 1 TOO !!! (Doe is part of FirstName)

strSQl = "SELECT name, firstname FROM customers WHERE (name LIKE '*" & dt(0).Text & "*') OR (firstname LIKE '*" & dt(0).Text & "*')"
strSQl = strSQl + " order by main"


*** Also what would I need to insert IF I DON'T WANT TO INCLUDE DUPLICATES

Thanx

What exactly do you want to see from the data posted?
Is dt(0).Text {first name] or [name]?

dt(0) is the input field that I would like to search from
dt(0) might be JOHN or DOE or JOHN DOE
I want to use that dt(0).text to look into {first name] or [name]

I have that.
So you want to see
John Doe
once

This is without criteria.

SELECT Trim(nz([firstName],"") & " " & Replace([name],nz([firstname],""),"")) AS Expr1
FROM Customers
GROUP BY Trim(nz([firstName],"") & " " & Replace([name],nz([firstname],""),""));
Assumes no blank [name]

Simplifying Server Workload Migrations

This use case outlines the migration challenges that organizations face and how the Acronis AnyData Engine supports physical-to-physical (P2P), physical-to-virtual (P2V), virtual to physical (V2P), and cross-virtual (V2V) migration scenarios to address these challenges.

This is fraught with possibilities for errors, since repeats of first and last name could cause some records not to show.

Oh, and I did the one for no duplicates.
Is your criteria working otherwise?

I think this will do the trick too:

strSQL = "SELECT [Name] & ' ' & FirstName FROM Customers WHERE [Name] & ' ' & FirstName  LIKE  '*" & dt(0).Text & "*'"

Open in new window



Not sure how you are defining 'duplicates'.  Are rows 1 and 3 duplicates, or are they different?

rows 1 and 3 are different
Nope, it is not working the way I want it to work (according to the code provided)
Basically what I want is :

There is NO 'JOHN DOE' EITHER IN [NAME] nor [FIRSTNAME]
There is 'DOE' in [FIRSTNAME] and 'JOHN' in [NAME]

**** But I want to search for 'JOHN DOE' and STILL GET IT

Okay...

Try this:

dim s()
dim x
dim strSQL
dim strWhere
dim strRoot

s = split(dt(0).Text, " ")
strRoot = " [Name] & ' ' & FirstName "

for each x in s
       strWhere = strWhere & strRoot & "LIKE '*" & x  & "*' OR"
Next
if Right( "nn" & strWhere, 2) = "OR" then strWhere = Left(strWhere, Len(strWhere) - 2)
strSQL = "SELECT [Name] & ' ' & FirstName FROM Customers WHERE " & strWhere

btw, what are you using for your code?  Access VBA, VB.Net, VBScript...?

dt(0).Text looks unusual for Access VBA.

try:
SELECT Customers.firstName, Customers.Name, Customers.Main
FROM Customers
WHERE (((Trim(nz([firstName],"") & " " & Replace(nz([name],""),nz([firstname],""),""))) Like "*" & [entername] & "*")) OR (((Customers.firstName) Like "*" & [entername] & "*")) OR (((Customers.Name) Like "*" & [entername] & "*"))
ORDER BY Customers.Main;
where [entername] is your criteria
