using C#,Xml,Sql 

 

Suppose we have two xml file,one have define source connection string,target connection string and other one xml having define mapping between srcdb and trgt db.

1- I have to read source connection and target connection. make a connection based on consetting xml file.

Note:- you can also define your connection string in Consetting xml file

2- I have to read second mapper xml file,according to source connection and target connection find first what tables are attached in both src db and targetdb . ex.- OrderHDR table column OrderId - 101,102,103 please insert first manually in sql.

3- Check this condition which is given in second mapper xml file

<TargetSAMPLE.Sales.SaleID AlternateValue="" Formula="" ConstantValue="" TfkRelation="" Tfk="" Tpk="" Src="OPTICS_SQL.OrderHDR.OrderID"/>

Note: This means OrderHDR table feild OrderID assign to targetdb "TargetSample", table name "Sales" ,column name "SalesID"

Note: Here OPTICS_SQL is source connection string name

4- Insert OrderID all value which you read from src db to targetdb sales table column salesId.
