class of attribute 0 = java.math.BigDecimal, value = 1 class of attribute 1 = java.lang.String, value = item1 class of attribute 2 = java.lang.String, value = item1 desc As you can see, the number attributes are converted into java.math.BigDecimal by default (this is specified in Table A-1 of the Appendix). If we change the program to comment out all method invocations in the main() method except for the method _demoStructWithCallable StmtGivesError(), we get the following error (as mentioned earlier, this is a bug in the Oracle implementation): URL:jdbc:oracle:thin:@(DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(PORT=1521) (HOST=rmenon-lap))(CONNECT_DATA=(SID=ora10g))) Exception in thread "main" java.sql.SQLException: ORA-03115: unsupported network datatype or representation ... To summarize, we get a SQLException when we return an object as an out parameter in a PL/SQL procedure. The workaround is to retrieve object column data as a ResultSet and then extract the column as a Struct object, as discussed alongside the description of the method _demoQueryWithCallableStmt() in the previous section.

You need to call addListeners to set the listeners you will be using. Take a look at this method to see the events you will be listening to.

Figure 12-1 Optimal hash join The steps are as follows: 1 Oracle reads the first data set and builds an array of hash buckets in memory A hash bucket is little more than a location that acts as the starting point for a linked list of rows from the build table A row belongs to a hash bucket if the bucket number matches the result that Oracle gets by applying an internal hashing function to the join column(s) of the row The number of buckets in the hash table always seems to be an even power of two (common values for small hash joins are 1,024 or 4,096 buckets).

The Struct interface does not expose any methods to create Struct objects in your Java program so that you can insert or update objects in the database. Thus, for inserting and/or updating data, you have to use the extended Oracle functionality exposed by the class oracle.sql.STRUCT. Inserting an object using oracle.sql.STRUCT in conjunction with either the PreparedStatement interface or the CallableStatement interface involves the following steps: 1. Create an oracle.sql.StructDescriptor object for the database object type. The StructDescriptor object contains information about the object type required to manually construct a STRUCT object later. You need only one StructDescriptor object for any number of STRUCT objects that correspond to the same SQL type. For example, to create a new StructDescriptor object for the object type item, assuming that conn is an initialized Connection object, you can use the following code: StructDescriptor itemDescriptor = StructDescriptor.createDescriptor( "BENCHMARK.ITEM", conn );; 2. Create an array of objects with the same number of elements as the number of attributes of the object type. Each element must be of the appropriate data type representing the object attribute (as per Table A-1 in the Appendix). If the object type consists of nested objects, you need to create a corresponding oracle.sql.STRUCT object in its place. 3. Construct an oracle.sql.STRUCT object, passing in the StructDescriptor you created in step 1, a Connection object, and the array of objects you created in step 2 as the object attribute values. 4. Use the setObject() method in the PreparedStatement or CallableStatement interface to set the value of the object and then insert it into the table containing the object.
