Hello All,
I wanted to query database and make an XML using WriteXML function in the
dataset. When I use WriteXML function the XML structure is according to some
default schema. I wanted the schema to be defined by me (given below).
I tried using ReadSchema function before calling the fill function in the
dataAdapter but that did not help

can someone please advice
Thanks in advance,
Praveen

Hi Praveen,

Thanks for pasting the schema here. This schema is a valid DataSet schema
and we can write the xml with the desired schema. But we have to make sure
whether the data has been filled to the 'I' Table. Please try to use
XmlWriteMode.WriteSchema to output the data and schema together. You can
check if the data is in the desired table. If you have any problem, please
post the xml here. Thanks!

Hello Kevin

I was able to get the desired result. there are 2 ways of doing this. One as
you mentioned.
and second is by making use of TableMapping like below.

dbAdptr.TableMappings.Add("Table","I")

The second approach is better because if we are calling a procedure
returning multiple cursors we can handle this situation by setting the table
mapping for each dataTable.

Praveen
