Exemple

The second function call to odbc_result() returns the value of the field whose field name is "val" in the current record of the query result. An error occurs if a column number parameter for a field is less than one or exceeds the number of columns (or fields) in the current record. Similarly, an error occurs if a field with a name that is not one of the fieldnames of the table(s) that is(are) being queried.
