Verify If The Data Exist. If Not Insert If It Does Update

Im using a store proc in SQL server.I use one table to store my hockey statistics data of each player in the league.When i submit my form i would like to check if there is any sheet of that player that allready exist .. If so then i do update.. if it does not exist i do the insert statement.Here the way i figured it out ! One store proc to do the work of the insert or update. And one to check if the player exist in the statistics table. But i just cant find a way to return a good value from my second store proc. Does my logic make sence ? any ideas ?thank you<code>create procedure Hockey_Player_UpdateForwardStatistics

 @LeagueID int, @GamePlayerID int, @Games int

as

declare @PlayerID int

@PlayerID = Hockey_CheckPlayerStatistics(@LeagueID, @GamePlayerID)

if @PlayerID = 0begininsert into Hockey_PlayerStatistics( Games)values( @Games)end

ELSE

beginupdate Hockey_PlayerStatistics set Games = @Gameswhere LeagueID = @LeagueID and PlayerID = @PlayerIDend</code>
