Python如何批量修改替换Excel Power Query里面的SQL脚本
背景 我们现行的BI技术栈主要是Python,MySQL,Excel&PowerBI,一般是ETL做好数据源和清洗之后,将其通过Power Query加载到Excel里面,这样可以用最简单的Excel切片器交互,也方便我们自动刷新和分发报表. 我们以现行的一个模型为例,这个模型名为转介绍数控一.xlsx.它使用了我们常超图SuperMap iObjects .NET Geometry转geoJSON&WKT&WKB
关键代码var geoJSONTxt = Toolkit.GeometryToGeoJson(geometry); var bytes = Toolkit.GeometryToWKB(geometry); var wktTxt = Toolkit.GeometryToWKT(geometry);SuperMap.Data.Toolkit中包含:static byte[] GemetryToWKB(Geometry geometry); static string GemetNetTopologySuite Geometry&WKT&WKB&GeoJSON互转
WKT To WKBprivate static byte[] ConvertWKTToWKB(string wkt) { WKBWriter writer = new WKBWriter(); WKTReader reader = new WKTReader(); var wkb = writer.Write(reader.Read(wkt)); return wkb; }WKB To WKTprivate static string ConvertWKBToWKT(NetTopologySuite Geometry&WKT&WKB&GeoJSON互转
WKT To WKB private static byte[] ConvertWKTToWKB(string wkt) { WKBWriter writer = new WKBWriter(); WKTReader reader = new WKTReader(); var wkb = writer.Write(reader.Read(wkt)); return wkb; } WKB To WKT private static string ConvertWKBToWKT(byte[] wkb超图SuperMap iObjects .NET Geometry转geoJSON&WKT&WKB
