in SQL Server, you should use 'Stuff'.

SQL

Select  CardNO As CardNo,
    JobCode As JobCode,
    Stuff(
    (
        Select  ', ' + User
            From    table3
            For Xml Path('')
    ), 1, 2, N'')   As User
    From    table1, table2

since I dont know the relations between your tables, this query is going to return two same rows. use 'where' in 'select' inside 'stuff' to filter data.

in Oracle you shoul use Replace.
for Oracle string concating, see this :http://asktom.oracle.com/pls/asktom/f?p=100:11:0::::P11_QUESTION_ID:2196162600402
