ClientDataSet sql查询找不到参数
AnsiString strsql = "select * from test where id =:vid and name =:vname"
ClientDataSet1-> Params->ParamByName("vid ")-> AsString= strid;
ClientDataSet1-> Params->ParamByName("vname")-> AsString= strName;
ClientDataSet1->ComandText = strsql;

当查询一次后，再次运行代码就找不到参数了，
提示 parameter "vid" not found


[解决办法]
前几个星期也有人问过，用酱子的顺序试试。
AnsiString strsql = "select * from test where id =:vid and name =:vname"
ClientDataSet1->ComandText = strsql;
ClientDataSet1-> Params->ParamByName("vid ")-> AsString= strid;
ClientDataSet1-> Params->ParamByName("vname")-> AsString= strName;

[解决办法]
clientDate清空一下看看
[解决办法]
Params属性加一下参数，再试。
