You have at least 2 issues in your INSERT
command.
1) You can't use WHERE
clause in INSERT INTO VALUES
statement.
2) In the INSERT INTO VALUES
statement the values must appear in brackets.
int s = sta.executeUpdate("INSERT INTO tblLeagueFixtures VALUES ('" + InputTeam1 + "', '" + InputTeam2 + "', '" + InputTeam1Goals + "', '" + InputTeam2Goals + "')");
To update data you must use correct syntax. For more information refer to this.
