The first call to <function>odbc_result</function> returns the
value of the third field in the current record of the query
result. The second function call to
<function>odbc_result</function> 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.

Field indices start from 1. Regarding the way binary or
long column data is returned refer to
<function>odbc_binmode</function> and
<function>odbc_longreadlen</function>.
<!--
If the requested field contains
binary data or is of datatype LONG,
longer than 4096 bytes, the contents is not
returned, instead it is sent directly to the client. Hint: If you
need to have binary data returned, use the SQL function HEX() to
retrieve the field in hexadecimal notation. E.g. "SELECT
HEX(binary_col) FROM mytable"
