用java调用oracle存储过程和函数

创建测试用表：
CREATE TABLE USER
(
   I_ID   VARCHAR(50) NOT NULL,
   I_NAME VARCHAR(50) NOT NULL
);

一：无返回值的存储过程
1，建立存储过程：
CREATE OR REPLACE
PROCEDURE TESTA(
    PARA1 IN VARCHAR2,
    PARA2 IN VARCHAR2)
AS
BEGIN
  INSERT INTO USER
    (I_ID,I_NAME
    ) VALUES
    (PARA1, PARA2
    );
END TESTA;

 

2，Java程序：

package com.hyq.src;

public class TestProcedureOne {

  public TestProcedureOne() {

  }

  public static void main(String[] args ){

    String driver = "oracle.jdbc.driver.OracleDriver";

    String strUrl = "jdbc:oracle:thin:@127.0.0.1:1521: hyq ";

    Statement stmt = null;

    ResultSet rs = null;

    Connection conn = null;

    CallableStatement cstmt = null;

    try {

      Class.forName(driver);

      conn =  DriverManager.getConnection(strUrl, " hyq ", " hyq ");

      CallableStatement proc = null;

      proc = conn.prepareCall("{ call HYQ.TESTA(?,?) }");

     // proc = conn.prepareCall("begin HYQ.TESTA(?,?); end;");

      proc.setString(1, "100");

      proc.setString(2, "TestOne");

      proc.execute();

    }catch (SQLException ex2) {

      ex2.printStackTrace();

    }catch (Exception ex2) {

      ex2.printStackTrace();

    }finally{

      try {

        if(rs != null){

          rs.close();

          if(stmt!=null){

            stmt.close();

          }

          if(conn!=null){

            conn.close();

          }

        }

      }catch (SQLException ex1)
      {

      }

    }

  }
}

二：有返回值的存储过程（非列表）

1，建立存储过程：
CREATE OR REPLACE
PROCEDURE TESTB(
    PARA1 IN VARCHAR2,
    PARA2 OUT VARCHAR2)
AS
BEGIN
  SELECT I_NAME INTO PARA2 FROM TESTTB WHERE I_ID= PARA1;
END TESTB;

 

2，Java程序：
package com.hyq.src;

public class TestProcedureTWO {

  public TestProcedureTWO() {

  }

  public static void main(String[] args ){

    String driver = "oracle.jdbc.driver.OracleDriver";

    String strUrl = "jdbc:oracle:thin:@127.0.0.1:1521:hyq";

    Statement stmt = null;

    ResultSet rs = null;

    Connection conn = null;

    try {

      Class.forName(driver);

      conn =  DriverManager.getConnection(strUrl, " hyq ", " hyq ");

      CallableStatement proc = null;

  // proc = conn.prepareCall("{ call HYQ.TESTB(?,?) }");

      proc = conn.prepareCall("begin HYQ.TESTB(?,?); end;");

      proc.setString(1, "100");

      proc.registerOutParameter(2, oracle.jdbc.OracleTypes.VARCHAR);

      proc.execute();

      String testPrint = proc.getString(2);

      System.out.println("=testPrint=is="+testPrint);

    }catch (SQLException ex2) {

      ex2.printStackTrace();

    }catch (Exception ex2) {

      ex2.printStackTrace();

    }finally{

      try {

        if(rs != null){

          rs.close();

          if(stmt!=null){

            stmt.close();

          }

          if(conn!=null){

            conn.close();

          }

        }

      }catch (SQLException ex1) {

      }

    }

  }

}

}

三：返回列表
由于oracle存储过程没有返回值，它的所有返回值都是通过out参数来替代的，列表同样也不例外，但由于是集合，所以不能用一般的参数，必须要用pagkage了.它是把游标（可以理解为一个指针），作为一个out 参数来返回值的.所以要分两部分:

1，建一个程序包：
CREATE OR REPLACE
PACKAGE TESTPACKAGE
AS
TYPE Test_CURSOR
IS
  REF
  CURSOR;
  END TESTPACKAGE;

2，建立存储过程：
CREATE OR REPLACE
PROCEDURE TESTC(
    PARA1 IN VARCHAR2,p_CURSOR OUT TESTPACKAGE.Test_CURSOR)
IS
BEGIN
  OPEN p_CURSOR FOR SELECT * FROM HYQ.TESTTB WHERE I_ID= PARA1;
END TESTC;

3，Java程序：
package com.hyq.src;

public class TestProcedureTHREE {

  public TestProcedureTHREE() {

  }

  public static void main(String[] args ){

    String driver = "oracle.jdbc.driver.OracleDriver";

    String strUrl = "jdbc:oracle:thin:@127.0.0.1:1521:hyq";

    Statement stmt = null;

    ResultSet rs = null;

    Connection conn = null;

    try {

      Class.forName(driver);

      conn =  DriverManager.getConnection(strUrl, "hyq", "hyq");

      CallableStatement proc = null;

      proc = conn.prepareCall("{ call hyq.testc(?,?) }");

 //   proc = conn.prepareCall("begin hyq.testc(?,?); end;");

      proc.setString(1, "100")

      proc.registerOutParameter(2,oracle.jdbc.OracleTypes.CURSOR);

      proc.execute();

      rs = (ResultSet)proc.getObject(2);

      while(rs.next())

      {

          System.out.println("<tr><td>" + rs.getString(1) + "</td><td>"+rs.getString(2)+"</td></tr>");

      }

    }catch (SQLException ex2) {

      ex2.printStackTrace();

    }catch (Exception ex2) {

      ex2.printStackTrace();

    }finally{

      try {

        if(rs != null){

          rs.close();

          if(stmt!=null){

            stmt.close();

          }

          if(conn!=null){

            conn.close();

          }

        }

      }catch (SQLException ex1) {

      }

    }

  }

}

 

四：调用函数返回列表

1，建一个程序包：

CREATE OR REPLACE
PACKAGE TESTPACKAGE
AS
TYPE Test_CURSOR
IS
  REF
  CURSOR;
END TESTPACKAGE;

2，建立函数：
CREATE OR REPLACE
FUNCTION TESTD(
    PARA1 IN VARCHAR2)
RETURN TESTPACKAGE.Test_CURSOR
IS
rc TESTPACKAGE.Test_CURSOR;
BEGIN
  OPEN rc FOR SELECT * FROM HYQ.TESTTB WHERE I_ID= PARA1;
  return rc;
END TESTD;

 

3，Java程序：
package com.hyq.src;

public class TestProcedureTHREE {

  public TestProcedureTHREE() {

  }

  public static void main(String[] args ){

    String driver = "oracle.jdbc.driver.OracleDriver";

    String strUrl = "jdbc:oracle:thin:@127.0.0.1:1521:hyq";

    Statement stmt = null;

    ResultSet rs = null;

    Connection conn = null;

    try {

      Class.forName(driver);

      conn =  DriverManager.getConnection(strUrl, "hyq", "hyq");

      CallableStatement proc = null;

      proc = conn.prepareCall("{ call ? :=HYQ.TESTD(?) }");

 //   proc = conn.prepareCall("begin ? :=HYQ.TESTD(?); end;");
 
   proc.registerOutParameter(1,oracle.jdbc.OracleTypes.CURSOR);

      proc.setString(2, "100")

      proc.execute();

      rs = (ResultSet)proc.getObject(1);

      while(rs.next())

      {

          System.out.println("<tr><td>" + rs.getString(1) + "</td><td>"+rs.getString(2)+"</td></tr>");

      }

    }catch (SQLException ex2) {

      ex2.printStackTrace();

    }catch (Exception ex2) {

      ex2.printStackTrace();

    }finally{

      try {

        if(rs != null){

          rs.close();

          if(stmt!=null){

            stmt.close();

          }

          if(conn!=null){

            conn.close();

          }

        }

      }catch (SQLException ex1) {

      }

    }

  }

}
