Oracle存储过程（分页、模糊查找、排序、按字段区间查找）etc.以及JAVA代码

-- 先创建包
CREATE OR REPLACE PACKAGE mypackage AS TYPE mycursor IS REF CURSOR;
END;

--创建分页存储过程
CREATE OR REPLACE PROCEDURE splitpage
(
v_tableName IN VARCHAR2,
v_pageSize IN NUMBER,
v_pageNow IN NUMBER,
v_myTotalRows OUT NUMBER,
v_myTotalPageCount OUT NUMBER,
v_cursor OUT mypackage.mycursor
)
IS
v_sql VARCHAR2(1000);
v_begin NUMBER:=(v_pageNow-1)*v_pageSize+1;
v_end   NUMBER:=v_pageNow*v_pageSize;
 
BEGIN
  v_sql:='select * from(
                 select rownum rn,a1.* from(
                   select * from ' ||v_tableName|| 
                 ') a1 where rownum<='||v_end||
          ') where rn>='||v_begin||'';
  OPEN v_cursor FOR v_sql;
  v_sql:='select count(*) from ' ||v_tableName||'';
  EXECUTE IMMEDIATE v_sql INTO v_myTotalRows;
  IF MOD(v_myTotalRows,v_pageSize)=0 THEN
    v_myTotalPageCount:=v_myTotalRows/v_pageSize;
  ELSE
    v_myTotalPageCount:=v_myTotalRows/v_pageSize+1;
  END IF;
END;

public YOURClass getSplitPage(int targetPage,int eachpagenum){
        Connection conn = DBConnection.getConn();//获取Oraccle 的Connection
                 
                //参数位置要与存储过程对应，其余用法跟pstmt类似
        String sql = "{call splitpage(?,?,?,?,?,?)}";
        try{
            cs = conn.prepareCall(sql);
            cs.setString(1,"tablename");// the name of db's table
            cs.setInt(2,eachpagenum);// Each page record numbers 
            cs.setInt(3,targetPage);// Target page number
 
            // register the output
            cs.registerOutParameter(4,OracleTypes.NUMBER);
            cs.registerOutParameter(5,OracleTypes.NUMBER);
            cs.registerOutParameter(6,OracleTypes.CURSOR);
 
            cs.execute();
            // get the value from CallableStatement
            totalRowsCount = cs.getInt(4);// 获取总记录数
            totalPagesCount = cs.getInt(5);// 获取总页数
            ResultSet rs = (ResultSet) cs.getObject(6);
 
            while(rs.next()){
                // 从rs中读取数据
            }
            return YOURClass;
        }catch (SQLException e){
            e.printStackTrace();
        }
        return null;
    }

　　下面就不给出JAVA代码了，因为都是类似的。用法跟pstmt一样，只是多了注册输出变量。

　　这几个下来想必大家也都清楚该怎么做了。如果需要添加什么条件，只需要在最内层字句中添加相应
