iOS10i 数据集转记录集出问题

    DatasetVector  *datasetVector = (DatasetVector *)layer.dataset;

    QueryParameter *parameter = [[QueryParameter alloc]init];

    parameter.cursorType = DYNAMIC;

    parameter.attriButeFilter = [NSString stringWithFormat:@"from = %@",layer.name];

    parameter.spatialQueryMode = SQM_IDENTITY;

    Recordset *recordset = [datasetVector query:parameter];

数据集有数据 转成记录集就是空的了

Answer 1

sql语句填写错误了，我们只填where部分，比如：smid>0
