    Joining 2 fields into 1 Thru SQL

    Is it possible utilizing a SQL statement to take 2 fields, such as firstname and lastname into another field called fullname combining the 2?

    Thank you.

    Re: Joining 2 fields into 1 Thru SQL

    Hey that worked great. May I ask another question? Are you not allowed to have spaces when naming columns.

    Your example

    SELECT lastname + ', ' + firstname as fullname
    FROM table

    Works perfect. I tried to give 'fullname' as 'Full Name' but generates an error, obviously because of the space, is there a way around this?

    Thank you

    I'm not sure if the is a standard way of doing this (not sure if I even like the idéa), but I belive that you can do this with apostophe (') or brackets ([]) in MS SQL, and back quote (`) in mySQL.

    What database are you targeting?

    Talking Re: Joining 2 fields into 1 Thru SQL

    Long story short, I've been shortlisted for an entry level position and they have asked to provide 2 solutions as a test prior to the interview. But its for Transact SQL so I will assume Windows SQL Server.

    The naming convention is not a big deal, I was just unsure how to create the one field from two thru SQL. If I couldn't do it on the fly, I was just going to add a field in the table itself and query that.

    Thank you.

    Is this to DISPLAY the combined 2 fields or do you need to add another field to your table, called fullname, and combine the two fields? IF you need to add a new field then you would need to use the alter table command, and set up this new field. Then do a update on the new field.

    Re: Joining 2 fields into 1 Thru SQL

    use

    SELECT lastname + ', ' + firstname as 'full name'
    FROM table

    This works for SQL Server

    select a as [my new colname] from tab

    Exclamation Re: Joining 2 fields into 1 Thru SQL

    I understand you can join several fields into 1 thru SQL. Is there a way to join several records with similar ids into a table?

    I have a table that holds projectIDs and Notes for each project. Another table Updates holds projectIDs and individual notes made about the project. I was wondering if there was an easy way to set Notes to the concatination of all individual notes.

    Re: Joining 2 fields into 1 Thru SQL

    You would have to run a query that used one of the JOIN options. You can select records from either one, or both tables. Then, you'd have a recordset that contained all the fields you wanted.

    No. Turning an N-long result column into a single concatenated string with all the values requires programming logic such as stored procedure or client. If you could guarantee that there would only ever be a max of 10 notes I can give you a wordy sql that will do it, but be aware it requires significant effort, first splitting the results from a column:

    #
    #
    #

    into a diagonal table:
    #__
    _#_
    __#

    into a flat:
    # # #

    into a concatenated:
    ###

    and the number of rows has to be known in advance



    Be careful using "join" to mean "concatenate"
