[mapguide-users] sqlserver view is no limit row search STSrid ?

[周宜和]

Hi Jackie

I try sqlserverProvider is work find. Thanks for great work.

 

I still have some question,source code url 

https://trac.osgeo.org/fdo/browser/trunk/Providers/GenericRdbms/Src/SQLServerSpatial/SchemaMgr/Ph/ColumnGeom.cpp#L100

https://trac.osgeo.org/fdo/browser/trunk/Providers/GenericRdbms/Src/SQLServerSpatial/SchemaMgr/Ph/Owner.cpp#L429

 

If first row is null data 

mSRID = owner->SampleColumnSrid( GetParent()->GetName(), GetName() );

mSRID will get -1

then next time into FdoSmPhSqsColumnGeom::GetSRID(),the mSRID is -1 will select top 1 then return -1 to mSRID,again and again.

How about select top 1 GeomColumnName from GeomTableName where GeomColumnName is not null

Hi Jackie,

I just wanted to confirm that the build works great and the speed at getting the STSrid in SQL Server is very fast now.
