Warning: mssql_query(): message: Incorrect syntax near ','

Answer 1

You have an additional comma in the second SQL line that breaks the syntax in your query.

...
$sql.= " --COALESCE(SUM(CASE kontrole.zakres & 4 WHEN 0 THEN 0 ELSE 1 END),0) 
AS ADR,";
$sql.= " COALESCE(SUM(dbo._IS_ADR(kontrole.pojazd_key)),0) AS ADR";
