ADORecordSet_db2::ADORecordSet_db2 (  $  id,

定義在 adodb-db2.inc.php 檔案之第 301 行.

參考 $mode, 及 ADORecordSet_odbc::ADORecordSet_odbc().

00302     {
00303         $this->ADORecordSet_odbc($id,$mode);
00304     }

函式成員說明文件

ADORecordSet_db2::MetaType (  $  t,
$  len = -1,
$  fieldobj = false
) 
 

Get the metatype of the column. This is used for formatting. This is because many databases use different names for the same type, so we transform the original type to our standardised version which uses 1 character codes:

參數:
t is the type passed in. Normally is ADOFieldObject->type.
len is the maximum length of that field. This is because we treat character fields bigger than a certain size as a 'B' (blob).
fieldobj is the field object returned by the database driver. Can hold additional info (eg. primary_key for mysql).
傳回值:
the general type of the data: C for character < 250 chars X for teXt (>= 250 chars) B for Binary N for numeric or floating point D for date T for timestamp L for logical/Boolean I for integer R for autoincrement counter/integer

依據ADORecordSet重新實作.
