oracle存储过程

第一个存储过程：

create or replace procedure proc_test_01(name varchar) is
begin
  dbms_output.put_line('Hello ' || name || '!');
end proc_test_01

第二个存储过程：

create or replace procedure proc_test_02(name varchar) is
begin
   -- 调用存储过程[proc_test_01]
   proc_test_01(name);
end proc_test_02

两个存储过程都能编译通过！！

执行存储过程：

SQL> set serveroutput on
SQL> exec proc_test_02( '宋建勇' );

Hello 宋建勇!

PL/SQL procedure successfully completed

SQL>

备注：写存储过程中的参数时不能指定参数的大小和长度，在执行过程中，两条语句不能写在同一行，否则无结果输出！
第二条执行语句也可以写成 

execute proc_test_02( '宋建勇' ); 

，结果是一样的，如下：

SQL>  set serveroutput on
SQL> execute proc_test_02( '宋建勇' );

Hello 宋建勇!

PL/SQL procedure successfully completed

一个带参数的存储过程

用java调用oracle存储过程总结

create or replace procedure procedure01(para1 in varchar2, para2 out varchar2) is
begin
  SELECT max(name) INTO PARA2 FROM tab WHERE id = PARA1;
end procedure01;

/* 有返回值的存储过程（非列表） */
	String procedure01(String str) throws SQLException {
		Connection connection = null;
		CallableStatement callableStatement = null;

		try {
			connection = getConnection();

			callableStatement = connection
					.prepareCall("{call procedure01(?,?)}");

			callableStatement.setString(1, str);
			callableStatement.registerOutParameter(2, Types.VARCHAR);

			callableStatement.execute();

			return callableStatement.getString(2);

		} finally {
			callableStatement.close();
			connection.close();
		}
	}

create or replace package package01 is
  type TypeCURSOR is REF CURSOR;
end package01

create or replace procedure procedure02(p_CURSOR out package01.TypeCURSOR) is
begin
  OPEN p_CURSOR FOR SELECT name,age FROM tab;
end procedure02

/* 返回列表的存储过程 */
	void procedure02() throws SQLException {
		
		Connection connection = null;
		CallableStatement callableStatement = null;
		ResultSet resultSet = null;

		try {
			connection = getConnection();

			callableStatement = connection.prepareCall("{call procedure02(?)}");

			callableStatement.registerOutParameter(1,
					oracle.jdbc.OracleTypes.CURSOR);

			callableStatement.execute();

			resultSet = (ResultSet) callableStatement.getObject(1);

			while (true == resultSet.next()) {
				System.out.print("姓名：" + resultSet.getString("name"));
				System.out.println("年龄：" + resultSet.getInt("age"));
			}

		} finally {
			resultSet.close();
			callableStatement.close();
			connection.close();
		}
	}

create or replace procedure procedure03(lc in varchar, jtbh in varchar, msg in varchar) is
begin
  insert into tab(name,id,message,reg_time)values(lc,jtbh,msg,sysdate);
end procedure03

/* 无返回值的存储过程 */
	boolean procedure03(String str1, String str2, String str3)
			throws SQLException {
		Connection connection = null;
		CallableStatement callableStatement = null;

		try {
			connection = getConnection();

			callableStatement = connection
					.prepareCall("{call procedure03(?,?,?)}");

			callableStatement.setString(1, str1);
			callableStatement.setString(2, str2);
			callableStatement.setString(3, str3);

			return callableStatement.execute();

		} finally {
			callableStatement.close();
			connection.close();
		}
	}

create or replace procedure pro_create_tab is
v_sql VARCHAR2(600);
flag  number;
begin
  select count(0) into flag from tab where TNAME='表01';
  if flag=1 then
    v_sql := 'drop table 表01';
    EXECUTE IMMEDIATE v_sql;
  end if;
  
  v_sql :='create table 表01 as select * from 表 where 1=0';
  EXECUTE IMMEDIATE v_sql;
  
end pro_create_tab

/* 无返回值的存储过程 */
	boolean procedure04()
			throws SQLException {
		Connection connection = null;
		CallableStatement callableStatement = null;

		try {
			connection = getConnection();

			callableStatement = connection
					.prepareCall("{call pro_create_tab()}");

			return callableStatement.execute();

		} finally {
			callableStatement.close();
			connection.close();
		}
	}
