|ADOdb Library for PHP Manual|
You can control the associative fetch case for certain drivers which behave differently. For the postgres, sybase, oci8po, mssql, odbc and ibase drivers and all drivers derived from them, ADODB_ASSOC_CASE will by default generate recordsets where the field name keys are lower-cased. Use the constant ADODB_ASSOC_CASE to change the case of the keys. There are 3 possible values:
0 = assoc lowercase field names. $rs->fields['orderid']
1 = assoc uppercase field names. $rs->fields['ORDERID']
2 = use native-case field names. $rs->fields['OrderID'] -- this is the default since ADOdb 2.90
To use it, declare it before you include adodb.inc.php.
use native-case for ADODB_FETCH_ASSOC
