In this exercise, you start with a basic JDBC program (JDBCPrimer.java), then learn how to programmatically get the JDBC version, implement both Implicit and Explicit Statement Cache, and Query Change Notification. In this section, you use the Apache Ant build tool, which is simpler than “M...
Microsoft JDBC Driver for SQL Server 會使用 JDBC 基本資料類型,將 SQL Server 資料類型轉換為 Java 程式設計語言可以理解的格式,反之亦然。 JDBC 驅動程式提供 JDBC 4.0 API 的支援,其中包括SQLXML資料類型和國家 (Unicode) 資料類型,例如NCHAR、NVARCHAR、LONGNVARCHAR和NCLOB。
it is possible to retrieve any of the basic SQL types with it. Getting all values withgetStringcan be very useful, but it also has its limitations. For instance, if it is used to retrieve a numeric type,getStringconverts the numeric value to a JavaStringobject, and the value has...

If your program imports both oracle.sql.* and java.sql.*, attempts to access the overlapping classes without fully qualifying their names may result in compiler errors. To avoid this problem, use one of the following steps: Use fully qualified names for BLOB, CLOB, and data classes. Import...
SEVEREIndicates a serious failure and is the highest level of logging. In the JDBC driver, this level is used for reporting errors and exceptions. WARNINGIndicates a potential problem. INFOProvides informational messages. FINEProvides tracing information including basic object creation and destruction. ...
Important Note:This feature only supports fully parameterized INSERT queries. If the INSERT queries are combined with other SQL queries, or contain data in values, execution falls back to the basic batch insert operation. For more information about how to use this property, seeUsing bulk copy API...
