This xml doc have more than one child nodes like Contacts. How to get the Node values and child node values from this xml, and want to insert this data to Table1 and Table2.

Note : If the Contact child node comes 2 time means, we will insert the 2 rows in Table2..

Answer 1

Try something like this:

INSERT INTO dbo.FirstTable(CustomerID, CustomerName, UserName, Password)
    SELECT
        @xmldata.value('(/Customers/Id)[1]', 'int'),
        @xmldata.value('(/Customers/Name)[1]', 'varchar(50)'),
        @xmldata.value('(/Customers/UserName)[1]', 'varchar(50)'),
        @xmldata.value('(/Customers/Password)[1]', 'varchar(50)')

Output from the SELECT statement is something like:

CustomerID  CustomerName   UserName  Password
     1        foo          TestUser  pwd

Second query:

INSERT INTO dbo.SecondTable(CustomerID, FirstName, LastName)
    SELECT
        @xmldata.value('(/Customers/Id)[1]', 'int'),
        Cont.value('(FirstName)[1]', 'varchar(50)'),
        Cont.value('(LastName)[1]', 'varchar(50)')
    FROM
        @xmldata.nodes('/Customers/Contacts') AS Cust(Cont)

Output from this SELECT is:

CustomerID   FirstName  LastName
    1        david      lawr
    1        john       peter
