问题
I'm using the map layer wizard for the first time in SSRS so we can add spatial data to the map.
We get this error from the wizard:
Unable to determine the spatial data type in the specified dataset field...
The data type for the spatial data is geography.
The spatial data looks like this when executed in the Query Designer:
POINT (2.41866741166689 48.9082239283949)
POINT (1.92902094274567 47.9294603618455)
POINT (2.25244361602031 48.9619440062058)
POINT (1.91174331024445 47.9109595746068)
POINT (1.32766100377444 43.6203441938353)
If the same query is run from SSMS, it looks like this:
0xE6100000010C4BF382AE407448400415C84C6E590340
0xE6100000010C0287A08EF8F647409244661045DDFE3F
0xE6100000010C5A9E2FFB207B48403421972801050240
0xE6100000010C0775C6529AF44740108C3D278096FE3F

All help will be appreciated.
回答1:
Are you using a parameter in the where clause of your dataset?
You are are getting this error because the mapping engine is trying to sample/test run your dataset and is tripping over the parameter. Try mapping your dataset without a parameter; if it works, your issue was in the parameter, not the datatypes.
Rework your query to pull all the rows you might need, and use a filter on the dataset
