odbc_longreadlen

Name

odbc_longreadlen — Alters handling of LONG columns.

Synopsis

bool odbc_longreadlen(result, length); resource result: Result identifier int length: Field length

Returns

Always TRUE

Description

This function works closely with odbc_binmode() to control how data from certain database fields (in this case, LONG and LONGVARBINARY) is handled. The length parameter controls the number of bytes sent through to PHP, while a value of 0 causes the column data to pass straight through.

Version

Existing since version 3.0.6

Example

Example 1349. Set LONG byte size

<?php
$db = odbc_connect("DSN","user","pass");
$result = odbc_exec($db, "SELECT Notes FROM Employees");
odbc_longreadlen($result, 4096);
echo odbc_result($result,1);
?>
