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.
