Hi Raja,
In a BizTalk map, draw a link from each of the 10 fields in your source schema to a String Concatenate Functoid as input parameters, and add 9 additional parameters to that functoid, each specifying the comma character, making sure to alternate your field parameter with the comma parameter, in the following order:
FieldParameter1
CommaParameter1
FieldParameter2
CommaParameter2
…
FieldParameter9
CommaParameter9
FieldParameter10
Then, in the same map, draw a link from the String Concatenate Functoid as output parameter to the "To" field in your destination schema, representing your SQL table.
Good luck.
