[mapguide-users] Re: Shape-Files and Joins

[Kori Maleski]

We are currently using shapefiles with joins with good results.

2 issues affect whether features display or not.

1 is geometry related - repair geometry in ArcMap
2 is the join field.  If the Shapefile ID is text, so must the SQL table.
If there are null IDs in the shapefile, the join may fail.

No error is thrown features just appear or disappear at different zoom
thresholds or all together.



Performance - turn caching on for the Shape FDO in the serverconfig.ini




Cheers,

Kori Maleski
