轻量级 Java 数据库连接 (JDBC) 适配器使您可以从符合 JDBC 的数据库中检索数据,或者在 Sterling B2B Integrator 中执行业务流程的过程中更新符合 JDBC 的数据库。 如果要检索或处理数据并且需要灵活地指定各种 SQL 查询,那么此适配器很有用。
首先,程式碼範例會建立自訂內容處理常式的執行個體,亦即 ExampleContentHandler。 接下來,它會建立並執行從 TestTable1 傳回一組數據的 SQL 語句。 然後,程式碼範例會取得 SAX 剖析器並剖析 XML 資料。showSetters 方法示範如何使用 SAX、ContentHandler 和 ResultSet 來設定 xml 資料行。 首先,它會使用 Connection...
