Hi,
I'm using 2005 and SQLXMLBulkLoad to load some rather large gml
files.
But I've got a problem (I Think) with specifying different
namespaces.
I'm a bit new to all this so your patience is appreciated.
Basically if I go through the XML file I'm loading and delete all
references to the 'gml:' namespace my schema works, and lots of
records are added to the database. If I use the original file with
references to the 'gml:' namespace I get no error and no records.
Any help would be greatly appreciated
Thanks in advance
Rich
vb.net code which appears to work ok.
--------------------------------------------------------
objBL = CreateObject("SQLXMLBulkLoad.SQLXMLBulkLoad")
objBL.ConnectionString = "provider=SQLOLEDB.1;data
source=MY_SERVER\SQLEXPRESS;database=MY_DB;uid=xxx;pwd=xxxx"
objBL.ErrorLogFile = "c:\error.log"
objBL.KeepIdentity = False
objBL.Execute("c:\MMAP_SCHEMA_FINAL.XML", "c:\MMAP.XML")
objBL = Nothing
Mapping Schema
-------------------------
<?xml version="1.0" ?>
<Schema xmlns="urn:schemas-microsoft-com:xml-data"
xmlns:dt="urn:schemas-microsoft-com:xml:datatypes"
xmlns:sql="urn:schemas-microsoft-com:xml-sql"
xmlns:osgb="http://www.ordnancesurvey.co.uk/xml/namespaces/
osgb"
xmlns:gml="http://www.opengis.net/gml">
<ElementType name="FeatureCollection" sql:is-constant="1"/>
<AttributeType name="fid" dt:type="string"/>
<ElementType name="TopographicPoint" sql:relation="MY_TABLE">
<attribute type="fid" sql:field="OS_ID" />
</ElementType>
</Schema>
