Loading either all shops or a specifically named shop from a DataTable

public  delegate DataTable loadDataTable();

DataTable shops = (cmbShop.Text == "All Shops") ? 
      new loadDataTable(() =>
       {
       Program.con.GET_Table_From_DataBase("sh", "select * from shops ");
       return Program.con.dst.Tables["sh"];
       }
      ).Invoke()
     :
       new loadDataTable(() =>
       {
        Program.con.GET_Table_From_DataBase("sh", "select * from shops where shopname='" +  cmbShop.Text + "' ");
        return Program.con.dst.Tables["sh"];
       }
  ).Invoke();

I am just setting the value of DataTable shops here.

I am learning about lambda expressions, so just for learning purposes, I want to know if this code can be shortened while using lambda expressions.

You don't need any lambda expressions at all.

You can write

if (cmbShop.Text == "All Shops")
    Program.con.GET_Table_From_DataBase("sh", "select * from shops ");
else
    Program.con.GET_Table_From_DataBase("sh", "select * from shops where shopname='" +  cmbShop.Text + "' ");

DataTable shops = Program.con.dst.Tables["sh"];
