Creating a username field

[artemetis]

Hi. I have a table with firstName & lastName. I need to run an sql to create a userName. I want the username to be the first initial of firstName and first seven letters of lastName.

I have this so far:

username: LCase(Left([firstName],1) & "" & (Left([lastname],7)))

but am running into a small problem.

Some of the last names are shorter than 7 characters which is ok, but these "shorter names" have trailing spaces and characters such as " / " and other words following. I need to be able to trim anything to the right of these characters and am stuck here.

functions like Trim() and Replace() may help.
But to be clear, you might want to show us real exemples of what you get vice what you want.

[artemetis]

firstName: jack
lastName: jones / group1
username: jjones /

desired username: jjones

I'm trying to have my qry return "jjones".
In the instance where the lastName is less than eight characters, it is including the first blank space and the backslash.

Function MakeUserName(firstName As String, lastname As String) As String
    Dim username As String
    lastname = Trim(Split(lastname, "/")(0))
    username = LCase(Left([firstName], 1) & (Left([lastname], 7)))
    MakeUserName = username
End Function
 

Output:

?MakeUserName("john", " jones / group1")
jjones

Thank you Mariostg!
Is there a way to use this in my qry or must I use a form?

Thank youa again

It would be best to place this function inside a module.
Then you can call the function from your your query:

username: MakeUserName([lastname],[firstname])
 

It gives you much more control and makes things cleaner.
