java往oracle存储过程中传递数组方…

java往oracle存储过程中传递数组方法小结，下面是一个例子，比如存储过程中要
接受一个数组，并且输出一个数组，则先注意数组在oracle中的定义方法如下：

CREATE TYPE array_table AS TABLE OF VARCHAR2 (50); -- Array of String

CREATE TYPE array_int AS TABLE OF NUMBER;                  -- Array of integers

接下来，一个存储过程，接受一个数组的输入，一个数组的输出，如下：

1. OR REPLACE PROCEDURE SchemaName.proc1 (p_array     IN     array_table,                                              len            OUT NUMBER,                                              p_arr_int      OUT array_int)AS   v_count   
2.  
3.  NUMBER;BEGIN   p_arr_int := NEW array_int ();   
4.  p_arr_int.EXTEND (10);     
5. := p_array.COUNT;   
6.  v_count := 0;    
7.  FOR i IN 1 .. p_array.COUNT   LOOP      
8.  DBMS_OUTPUT.put_line (p_array (i));    
9.    p_arr_int (i) := v_count;     
10.   v_count := v_count + 1;    
11. END LOOP;END;/

然后是JAVA代码，传入一个数组，返回一个数组的输出

1. import java.math.BigDecimal;  
2. import java.sql.CallableStatement;  
3. import java.sql.Connection;  
4. import java.sql.DriverManager;  
5. import java.sql.Types;  
6. import oracle.jdbc.OracleCallableStatement;  
7. import oracle.jdbc.internal.OracleTypes;  
8. import oracle.sql.ARRAY;  
9. import oracle.sql.ArrayDescriptor;    
10. public class TestDatabase {        
11.   public static void passArray()     
12. {        
13.  try{     
14.                  Class.forName("oracle.jdbc.OracleDriver");          
15.              Connection con = DriverManager.getConnection("jdbc:oracle:thin:url ","UserName","Password");;                         String array[] = {"one", "two", "three","four"};        
16.                    
17.  ArrayDescriptor des = ArrayDescriptor.createDescriptor("SchemaName.ARRAY_TABLE",   
18.            
19.  ARRAY array_to_pass = new ARRAY(des,con,array);     
20.                        
21. st = con.prepareCall("call SchemaName.proc1(?,?,?)");             
22.           st.setArray(1, array_to_pass);             st.registerOutParameter(2, Types.INTEGER);            st.registerOutParameter(3,OracleTypes.ARRAY,"SchemaName.ARRAY_INT");    
23.          
24.  
25.  st.execute();                 
26.          System.out.println("size : "+st.getInt(2));            
27.   // Retrieving array from the resultset of the procedure after execution -           
28.  
29.    ARRAY arr = ((OracleCallableStatement)st).getARRAY(3);             
30.  BigDecimal[] recievedArray = (BigDecimal[])(arr.getArray());           
31.    for(int i=0;i"element" + i + ":" + recievedArray[i] + "\n");                     
32.  } catch(Exception e) {       
33.       System.out.println(e);   
34.       }    
35.  }    
36.   public static void main(String args[])  
37.        
38.  passArray();   
39.   }  
40.  
41. }
