[Oracle to SQL Server Migration] ROWNUM

Problem
We used rownum = 1 in Oracle as bellows:

If we migrate to Microsoft SQL Server, how to translate it?

1 2 3 4 5 6 7 8 9 10 11 12 13

SELECT to_char(STA_DATE, 'YYYY') - 1911 ACCOUNT_YR, age, fund_id, (select fund_name from dbm031fa where fund_id=dbm034fa.fund_id and rownum=1) fund_name, mge_type, IN_AMT, OUT_AMT, (IN_AMT/OUT_AMT)*100 RATIO FROM dbm034fa WHERE to_char(STA_DATE, 'YYYY') - 1911 BETWEEN '101' AND '103' AND age = '379000000A' AND fund_id='010401C00010' AND mge_type='G'

How-To
We can use TOP N to fulfill this requirement.
The SQL statement will be amended as following:

1 2 3 4 5 6 7 8 9 10 11 12 13

SELECT YEAR(STA_DATE) - 1911 ACCOUNT_YR, age, fund_id, (select TOP 1 fund_name from dbm031fa where fund_id=dbm034fa.fund_id) fund_name, mge_type, IN_AMT, OUT_AMT, (IN_AMT/OUT_AMT)*100 RATIO FROM dbm034fa WHERE YEAR(STA_DATE) - 1911 BETWEEN '101' AND '103' AND age = '379000000A' AND fund_id='010401C00010' AND mge_type='G'
