The first call to <span class="function"><strong>odbc_result()</strong></span> returns the
|
|
value of the third field in the current record of the query
|
|
result. The second function call to
|
|
<span class="function"><strong>odbc_result()</strong></span> 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.
