differs from eq_ref in that it uses only the leftmost prefix of the index for the association operation, or that the index is not unique and primary KEY. Ref can be used with indexed columns that use the = or To show that we re-establish the People2 and PEOPLE_CAR2 tables above, we still use MyISAM but do not specify primary key for the ID. We then set up a non-unique index for the ID and people_id, respectively. reate index people_id on people2 (ID

activated only After the Insert, Update, and Delete operations are completed. The Instead Of trigger is activated before these operations are performed, and the original SQL operations are no longer executed, instead, execute the SQL statement of the trigger instead of the original statement. In the above example, When deleting a product record, replace the delete operation with Instead to query the inventory Of the product. The database operations are as follows: 1. Receive SQL statements, but

, adding a @override system in front of the method can help you check the correctness of the method. For example, public void onCreate (bundle savedinstancestate) {...} This is the correct wording if you write the public void OnCreate (bundle savedinstancestate) {...} so the compiler returns the following error--the method OnCreate (Bundle) of type HelloWorld must override or implement a Supertype method to ensure that you correctly rewrite Onc Reate

However, to keep it simple, httpclient does not expose all of these attributes-which makes it awkward, because there are many properties that are seldom used.If you need to access these properties then there is the ways of doing it:use either Httpclienthandler or Webrequesthand Ler. Both is httpmessagehandlers hooked in as part of the Httpm

JPA Java persistence API. JPA uses JDK 5.0 annotations or XML to describe the ing relationship between objects and Relational Tables, and persistently stores object objects in the database at runtime. Baidu Encyclopedia: http://baike.baidu.com/view/1036852.htm JTA Java transaction API, translated as Java transaction API. JTA allows applications to execute Distributed Transaction Processing-accessing and updating data on two or more network computer resources. The JTA support of the JDBC driver
