Added code block

Solution 2

C#

var allRows =
    from
        dataTable1Rows in dataTable1.AsEnumerable()
    join
        dataTable2Rows in dataTable2.AsEnumerable()
    on
        dataTable1Rows.Field<int>("ID") equals dataTable2Rows.Field<int>("ID")
    select
        dataTable2Rows;

DataTable joinedDataTable = allRows.CopyToDataTable();

and this joinedDataTable you can bind to rdlc , if you want to do it at c# side , otherwise if you want a sql server query a simple join between two tables should work

SQL

SELECT table1.ID ,table1.Name, table2.Skill, table2.Proficiency
FROM datatable1 table1
INNER JOIN datatable2 table2 ON table1.ID = table2.ID where table1.ID='R1'

Hope this helps

Solution 1

SQL

SELECT t1.Name, t2.Skill, t2.Proficiency
FROM table1 t1 
INNER JOIN table2 t2 ON t1.ID = t2.ID
WHERE t1.ID = 'R1'

This will give you the name, skill, and proficiency where the ID is R1.
