oracle存储过程的创建和使用

创建存储过程：

格式：create or replace procedure procedure_name(参数 参数类型)

Is/as

变量1 变量1的类型；

begin

----------业务逻辑----------

end；

-- plsql里面调用存储过程
begin
  proc(10);
end;

--创建存储过程
create procedure proc(dno number)
is
       cursor c is select * from emp where deptno = dno;
begin
--使用游标循环集合（list）
for r in c loop
  dbms_output.put_line(r.ename || ' : ' || r.sal);
  end loop;
end; 

Java代码里调用存储过程

public List<Map<String, Object>> queryAllData(final String curragency,
            final String systype, final String userid,
            final String pisoffsetcheck, final String whereSql) {
        final List<Map<String, Object>> list = new ArrayList<Map<String, Object>>();
        getJdbcTemplate().execute(new ConnectionCallback() {
            public Object doInConnection(Connection conn) throws SQLException,
                    DataAccessException {
                ResultSet rs = null;
                String sql = "{call PKG_GCFR_OFFSET.queryAllData(?,?,?,?,?,?)}";
                CallableStatement cstmt = conn.prepareCall(sql);
                cstmt.setString(1, curragency);
                cstmt.setString(2, systype);
                cstmt.setString(3, userid);
                cstmt.setString(4, pisoffsetcheck);
                cstmt.setString(5, whereSql);
                cstmt.registerOutParameter(6, OracleTypes.CURSOR);
                cstmt.execute();
                rs = (ResultSet) cstmt.getObject(6);
                if (rs != null) {
                    ResultSetMetaData rsmd = rs.getMetaData();
                    int numberOfColumns = rsmd.getColumnCount();
                    while (rs.next()) {
                        Map<String, Object> map = new HashMap<String, Object>();
                        for (int r = 1; r <= numberOfColumns; r++) {
                            map.put(rsmd.getColumnName(r).toLowerCase(),
                                    rs.getObject(r));
                        }
                        list.add(map);
                    }
                }
                if (cstmt != null) {
                    cstmt.close();
                }
                if (rs != null) {
                    rs.close();
                }
                if (conn != null) {
                    conn.close();
                }
                return list;
            }
        });
        return list;
    }
