Combining multiple rows into single column
Below is what you need

CREATE TABLE customers
    ([id 1] int, [status] varchar(4), [id 2] int, [name] varchar(4), [category] varchar(6))
;

INSERT INTO customers
    ([id 1], [status], [id 2], [name], [category])
VALUES
    (001, 'open', 011, 'john', 'person'),
    (001, 'open', 011, 'john', 'male')
;
select * from dbo.customers


---- You have to use STUFF function with FOR XML PATH

 select distinct cs.[id 1]
    ,cs.[status]
    ,cs.[id 2]
    ,cs.[name]
    ,stuff((
            select ',' + c.[category]
            from dbo.customers c
            where cs.[id 1] = c.[id 1]
            for xml path('')
            ), 1, 1, '') as [category]
     from dbo.customers cs
