Hi all

Please check the below code

SQL

If (DateTime.Now = "01/01/2013") Then
               Dim sql00 = "select sum(EL),sum(ML) from attendance where Emp_name = '" + ComboBox1.Text + "'"
               Dim sql000 = sql00 + " SELECT 15+ sum(EL) as el, 14 + sum(ML) as ml from attendance where Emp_name = '" + ComboBox1.Text + "' "
               DataGridView2.Rows.Add(sql000)
           End If

my requirement is if the date hits 1/1/2013 then it should add the result of the first query(i.e. it will give the remaining leaves of a particular emp) to the nxt query(i.e. predefined number of leaves for each emp) and the result i want to display in the gridview

No use in adding two queries..
1. Execute the first query and Get the result..
2. Execute the second query and get the result..
3. add both the results based on ur requirement..
if u have any clarifications reply to this..

hi,

Here is the code to connect to the database in Ms Access.

Connection string for MS Access via OLE DB:
Dim connection As OleDbConnection
connection = new OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\NorthWind.mdb;User Id=;Password=;")
connection.Open();

After connecting to the database

dim da as new oledb.oledbdataadapter("your query",connection)
dim ds as new dataset
da.fill(ds)

Now u can set the data to the grid....

DataGridView1.DataSource = ds
DataGridView1.DataMember = "table name"

Hope this helps

just update your query

SQL

select sum(EL),sum(ML),15+ sum(EL) as el, 14 + sum(ML) as ml from attendance where Emp_name = '" + ComboBox1.Text + "'"
