Help in displaying records in single row

Hi,

I've written the following sql,but it is displaying the results in multiple rows,Could any body advise me on how to display the returned records in only one row.

Select

CASE WHEN data_center.abbrev IN ('2BELL') THEN '2BELL' END AS data_center,
CASE WHEN data_center.abbrev IN ('ALN') THEN 'Allen' END AS data_center,
CASE WHEN data_center.abbrev IN ('GLEN') THEN 'Glenridge' END AS data_center,
CASE WHEN data_center.abbrev IN ('NAS') THEN 'Nashville' END AS data_center,
CASE WHEN data_center.abbrev IN ('ALLE') THEN 'Schaumberg' END AS data_center,
CASE WHEN data_center.abbrev IN ('B2DE') THEN 'HOFFMANESTATES' END AS data_center,
CASE WHEN data_center.abbrev IN ('DK') THEN 'Unknown' END AS data_center,
CASE WHEN data_center.abbrev IN ('B2DL', 'B9PD', 'B9PPD', 'B9PR') THEN 'BOTHELL' END AS data_center,
CASE WHEN data_center.abbrev IN ('SD') THEN 'SanDiego' END AS data_center,
CASE WHEN data_center.abbrev IN ('HWY') THEN 'Hayward' END AS data_center,
