Hallo everybody, I have a some difficulties with QGIS and a MySQL database. I try to make it not so long, and work enviroment is WIN 7 64b; QGIS dev, MySQL 5.1.63
In my project (a GIS for an archaeological excavation) lot of data are stored in a MySQL database which was made before I joined it. Originally no geometry field was inserted in the MySQL tables and thereafter I have many features without stored geometry. My approach at the beginning was to create shapefiles (point and polygons mainly) of the features which I needed and to join them with the MySQL table that I imported into QGIS. Then now I have shapefiles MySQL tables Both have an ID which allow to join them together. This worked just fine, but now I want to get rid of this double approach and use the MySQL database as a complete geodatabase (I know I should transfer it in postGRE but it is not a short-term possibility). The reasons are: a) I want to create a webgis of the project; b) since we are now more persons who are working with GIS I would like that more than one user could work on the same shapefile at the same time; c) it is more "elegant". Now my question is how I merge the spatial information from the shapefiles into the MySQL tables? for the point shapefiles it was not a big problem since I had the lat long coordinates stored in the db, I just create a query which writes them in the POINT field. for the polygons is not so easy. I tried to install the QGIS plugin "export to MySQL" with the idea: - export the shapefile into MySQL - update the table with the geometry field but the plug-in does not work since a module is missing (MySQLdb). There is already a lot of documentation on it which I read. An installer for is also available BUT it is not working with my OSGEO installation. It seems that it is installing the module in a second installation of php that I have and not in for the php installed by the OSGEO, which is the one that QGIS is calling. Compiling it by myself is out of my skills. (of course I could export my shapefile in .csv, import it in MySQL and than run the query BUT I was looking for something simpler and that I could use often) Finally: somebody who had success in installing the export to Mysql plug-in in one OSGEO installation could tell me what I should do? Anybody has some suggestion how to solve my problem?
