odbc_longreadlen

bool odbc_longreadlen(resource result, int length)

Alters handling of LONG columns.

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:

Set LONG byte size
$db = odbc_connect("DSN","user","pass"); 
$result = odbc_exec($db, "SELECT Notes FROM Employees"); 
odbc_longreadlen($result, 4096); 
echo odbc_result($result,1);
