    How can i build the sql query for checking the duplicate value in the same column and join in a single query?

    Example:
    ColumnA = Company Name
    ColumnB = Employee number

    ColumnA has 3 ACME COMPANY record, each one has 67, 89 and 102 employees, the result must be:

    ACME COMPANY, 258 employees.
