<para>
Returns the string contents of the field, &false; on error, &null; for
NULL data, or &true; for binary data.
</para>
<para>
<parameter>field</parameter> can either be an integer containing
the column number of the field you want; or it can be a string
containing the name of the field. For example:
<informalexample>
<programlisting role="php">
<![CDATA[
<?php
$item_3 = odbc_result($Query_ID, 3);
$item_val = odbc_result($Query_ID, "val");
?>
]]>
</programlisting>
</informalexample>
</para>
<para>
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.
</para>
<para>
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"
-->
