I have a problem when i try to change a query with LIMIT from MYSQL to SQL-Server.
Check that :
SELECT * FROM tableEating WHERE person = \'$identi
LIMIT does not work in T-SQL.
You have to use TOP instead, like this:
SELECT TOP(1) * FROM tableEating WHERE person='$identity';
I hope that will work for you.
As Aaron says, you also need an ORDER BY if you don't want to get an arbitrary row.
ORDER BY
