预定义常量

Pdo\Odbc::ATTR_USE_CURSOR_LIBRARY

此选项控制是否使用ODBC游标库。ODBC游标库支持一些高级ODBC功能(例如块可滚动游标),这些功能可能未由驱动程序实现。支持以下值:

Pdo\Odbc::SQL_USE_IF_NEEDED
在需要时使用ODBC游标库。这是默认值。
Pdo\Odbc::SQL_USE_DRIVER
从不使用ODBC游标库。
Pdo\Odbc::SQL_USE_ODBC
始终使用ODBC游标库。

Pdo\Odbc::ATTR_ASSUME_UTF8
仅限Windows。如果为true,则在读取或写入数据库数据时,将UTF-16编码的字符数据(CHARVARCHARLONGVARCHAR)转换为UTF-8。如果为false(默认值),则字符编码转换可能由驱动程序完成。
