范例

The first call to odbc_result() returns the value of the third field in the current record of the query result. 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.

Example #1 odbc_result() examples

<?php
$item_3   
odbc_result($Query_ID3);
$item_val odbc_result($Query_ID"val");
?>

注释

Field indices start from 1. Regarding the way binary or long column data is returned refer to odbc_binmode() and odbc_longreadlen().
