Check_MK Werk 4123: active check check_sql: changed handling of query results and fixed hostname parameter

ID: 4123 Title: active check check_sql: changed handling of query results and fixed hostname parameter Component: Checks & Agents Level: 1 Class: Bug Fix Version: 1.4.0i4 If the used SQL query results in only one column its value is shown in check output now. Otherwise the second column of the result is used for check output. Also, the hostname parameter has been fixed to prevent erros like this: Error while connecting to database: [2005] Unknown MySQL server host "10.11.12.13"
