The JDBC-ODBC Bridge that comes with JDK 1.2 is a good example of this kind of driver. Type 2 − JDBC-Native API In a Type 2 driver, JDBC API calls are converted into native C/C++ API calls, which are unique to the database. These drivers are typically provided by the database v...
JDBC Drivers: Type 1 and 2 JDBC Type 3: Pure Java Driver for Database Middleware. See the right side of the second picture shown below. This style of driver translates JDBC calls into the middleware vendor's protocol, which is then translated to a DBMS protocol by a middleware server. Th...
Because so many ODBC and JDBC drivers exist and only the main ones have been heavily tested, these table types cannot be ranked as stable. Use them with care in production applications. These types can be used to access tables belonging to the current or another database server. Six types ...

It discusses functionality of the generic, weakly typed oracle.sql.STRUCT class, as well as how to map to custom Java classes that implement either the JDBC standard SQLData interface or the Oracle ORAData interface. This chapter also describes how JDBC drivers access SQLJ object types in SQL ...
BIT 类型用于存储整数数据 1、0 或 NULL,可以用来支持 ODBC 和 JDBC 的布尔数据类型。DM 的 BIT 类型与 SQL SERVER2000 的 BIT 数据类型相似。 INTEGER/INT 类型 语法如下: INTEGER INT 功能: 用于存储有符号整数,精度为 10,标度为 0。取值范围为:-2147483648(-2^31)～+2147483647(2^31-1)。
