Solution 1

Use top 1, if you are using sqlserver.If you are using oracle where rownum=1
eg SQL Server: select top 1 * from (your select query) alias;
eg Oracle: select * from (your select query) alias where alias.rownum=1;

Used Distinct keyword.
Apply Distinct on ID field ,you will get distinct record for each id.
