我的oracle分页存储过程
create or replace package TX_PKG_PAGEPACKAGE is type TX_RESULTLIST is ref cursor; procedure TX_PRC_PAGINATION(tx_resultlist out TX_RESULTLIST,insql in varchar2,currentpage in number,pagecount in number); end; create or replace package body TX_PKG_PAGEPACKAGE is procedure TX_PRC_PAGINATION(tx_resultlist out TX_RESULTLIST, insql in varchar2, currentpage in number, pagecount in number) as strSql varchar2(2000); begin strSql:='select * from (select rownum P_TX_ROWNUM, P_TX_TABLE.* from ('|| insql ||') P_TX_TABLE where rownum <='|| pagecount * currentpage ||') where P_TX_ROWNUM > '||(currentpage - 1) * pagecount; open TX_RESULTLIST for strSql; end TX_PRC_PAGINATION; end TX_PKG_PAGEPACKAGE;
以上是sql。
先声明一个游标,做返回结果集。
然后把要查询的sql当做参数传入,动态执行,返回结果集。
c#:
主方法: public DataSet SelectDsByProcedure(IDbConnection conn, string procedureName, IDbDataParameter[] parameters) { DataSet ds = new DataSet(); OracleDataAdapter sqlDA = new OracleDataAdapter(); OracleCommand command = new OracleCommand(procedureName, (OracleConnection)conn); command.CommandType = CommandType.StoredProcedure; foreach (OracleParameter parameter in parameters) { command.Parameters.Add(parameter); } sqlDA.SelectCommand = command; sqlDA.Fill(ds); Connection.Close(); return ds; } 程序中调用: OracleParameter[] paramDic = { new OracleParameter("tx_resultlist",OracleType.Cursor), new OracleParameter("insql",OracleType.VarChar), new OracleParameter("currentpage",OracleType.Int32), new OracleParameter("pagecount",OracleType.Int32) }; paramDic[0].Direction = ParameterDirection.Output; paramDic[1].Value = "select * from student order by stu_gender"; paramDic[2].Value = 1; paramDic[3].Value = 2; DataSet ds = db.SelectDsByProcedure("TX_PKG_PAGEPACKAGE.TX_PRC_PAGINATION", paramDic);
存储过程中没做一些判断。比如传入存储过程的参数是否合法。是否有结果集之类的。请自行添加。
