Java 调用PL/SQL Array

Java 调用PL/SQL Returning Object Array

实现在java调用返回值是数组的存储过程方法。

1. 数组：CYJ_ARRAY

CREATE OR REPLACE TYPE CYJ_ARRAY is VARRAY(20) OF integer

2. 存储过程：getTestArray()

CREATE OR REPLACE FUNCTION getTestArray RETURN CYJ_ARRAY
AS
  l_test CYJ_ARRAY :=CYJ_ARRAY();

   begin
    FOR i IN 1..10 LOOP
      l_test.extend;
      l_test(l_test.count) := i;
      dbms_output.put_line(l_test(l_test.count));
    END LOOP;
    RETURN  l_test;
  END;
3. 调用存储过程的java 类

public class TestOracleReturnArray  {


public static void main(String[] args) throws SQLException {
Connection conn = null;
CallableStatement cstmt = null;
ResultSet rs = null;
try {
 
  DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
  conn = DriverManager.getConnection("jdbc:oracle:thin:@localhost:1521:ora","zzz","sss");
 
  conn.setAutoCommit(false);
  String procedure = "{? = call getTestArray() }";// 调用存储过程
  cstmt = conn.prepareCall(procedure);
  cstmt.registerOutParameter(1, OracleTypes.ARRAY,"CYJ_ARRAY"); //注：type name：区分大小，不是包中的type, 使用包中定义的type如何调用还不知道
 
  cstmt.execute();
  ARRAY array = (ARRAY)cstmt.getObject(1);
  Object[] items = (Object[])array.getArray();
  Object obj;
 
  for (int i = 0; i < items.length; i++) {
    obj = items[i];
  
   System.out.println(obj);
  
   } // for
} catch (Exception e) {
  e.printStackTrace();
} finally {
  //DbConnRestore.connRestore(rs, cstmt, null, conn);
}
}

}

请问楼主有没有碰到过查询出来的VARCHAR2型的字符都是?的情况?
