Table Structure

Customer_Name   Month   Year    Effective_Date  Value
  Sanjay         Jan    2018      01-Jan-18       10
  Sanjay         Feb    2018      01-Feb-18       11
  Sanjay         Mar    2018      01-Mar-18       11
  Sanjay         Apr    2018      01-Apr-18       13
  Sanjay         May    2018      01-May-18       15
  Sanjay         Jun    2018      01-Jun-18       15
  Sanjay         Jul    2018      01-Jul-18       15
  Sanjay         Aug    2018      01-Aug-18       16
  Sanjay         Sep    2018      01-Sep-18       14

```

I want output like this:

```
Customer_Name   Month   Year    Effective_Date  Value
  Sanjay         Jan    2018      01-Jan-18       10
  Sanjay         Feb    2018      01-Feb-18       11
  Sanjay         Apr    2018      01-Apr-18       13
  Sanjay         May    2018      01-May-18       15
  Sanjay         Aug    2018      01-Aug-18       16
  Sanjay         Sep    2018      01-Sep-18       14

```

**Logic: If simultaneous rows value will same then only first row will come.**

I can do this using cursor. But I don't want to use cursor. Is there any other way to do do this?
