31 |
* <P>A connection (session) with a specific
|
|
32 |
* database. SQL statements are executed and results are returned
|
|
33 |
* within the context of a connection.
|
|
34 |
* <P>
|
|
35 |
* A <code>Connection</code> object's database is able to provide information
|
|
36 |
* describing its tables, its supported SQL grammar, its stored
|
|
37 |
* procedures, the capabilities of this connection, and so on. This
|
|
38 |
* information is obtained with the <code>getMetaData</code> method.
|
|
39 |
*
|
|
40 |
* <P><B>Note:</B> When configuring a <code>Connection</code>, JDBC applications
|
|
41 |
* should use the appropritate <code>Connection</code> method such as
|
|
42 |
* <code>setAutoCommit</code> or <code>setTransactionIsolation</code>.
|
|
43 |
* Applications should not invoke SQL commands directly to change the connection's
|
|
44 |
* configuration when there is a JDBC method available. By default a <code>Connection</code> object is in
|
|
45 |
* auto-commit mode, which means that it automatically commits changes
|
|
46 |
* after executing each statement. If auto-commit mode has been
|
|
47 |
* disabled, the method <code>commit</code> must be called explicitly in
|
|
48 |
* order to commit changes; otherwise, database changes will not be saved.
|
|
49 |
* <P>
|
|
50 |
* A new <code>Connection</code> object created using the JDBC 2.1 core API
|
|
51 |
* has an initially empty type map associated with it. A user may enter a
|
|
52 |
* custom mapping for a UDT in this type map.
|
|
53 |
* When a UDT is retrieved from a data source with the
|
|
54 |
* method <code>ResultSet.getObject</code>, the <code>getObject</code> method
|
|
55 |
* will check the connection's type map to see if there is an entry for that
|
|
56 |
* UDT. If so, the <code>getObject</code> method will map the UDT to the
|
|
57 |
* class indicated. If there is no entry, the UDT will be mapped using the
|
|
58 |
* standard mapping.
|
|
59 |
* <p>
|
|
60 |
* A user may create a new type map, which is a <code>java.util.Map</code>
|
|
61 |
* object, make an entry in it, and pass it to the <code>java.sql</code>
|
|
62 |
* methods that can perform custom mapping. In this case, the method
|
|
63 |
* will use the given type map instead of the one associated with
|
|
64 |
* the connection.
|
|
65 |
* <p>
|
|
66 |
* For example, the following code fragment specifies that the SQL
|
|
67 |
* type <code>ATHLETES</code> will be mapped to the class
|
|
68 |
* <code>Athletes</code> in the Java programming language.
|
|
69 |
* The code fragment retrieves the type map for the <code>Connection
|
|
70 |
* </code> object <code>con</code>, inserts the entry into it, and then sets
|
|
71 |
* the type map with the new entry as the connection's type map.
|
|
72 |
* <pre>
|
|
73 |
* java.util.Map map = con.getTypeMap();
|
|
74 |
* map.put("mySchemaName.ATHLETES", Class.forName("Athletes"));
|
|
75 |
* con.setTypeMap(map);
