With this article, we will be knowing how to convert an integer to Year, Month, Days from an integer value. The prerequisites of this article are you should be having a MSSQL server on your computer.

#### What is a query?

A query is a statement or a group of statements written to perform a specific task, like retrieve data, save data into a database.

Let us make a database first to perform this task –

#### Step 1:

`CREATE DATABASE GFG`

Step 2: Using the database

`USE GFG`

Step 3: Create a table with name inttodate –

```CREATE TABLE inttodate (id bigint,
value bigint);```

Step 4: Describe this table – Created Table schema

Step 5: Insert some values to the table –

```INSERT INTO [dbo].[inttodate]
([id]
,[value])
VALUES
(1
,35110011)

INSERT INTO [dbo].[inttodate]
([id]
,[value])
VALUES
(2
,35220011)``` Data inserted into the table

Step 6: Now run the query to check what is the year, month, day conversion of the inserted data –

Here we will be creating a variable using dateadd function, and then we will split the values into the year, month and date.

```DECLARE @variable_date DATETIME = DATEADD(SECOND, (SELECT [value]
FROM [dbo].[inttodate] WHERE [id] = '1'), 0)

SELECT CAST(DATEPART(YEAR, @variable_date) - 1900 AS VARCHAR(10))
+ ' year ' + CAST(DATEPART(MONTH, @variable_date) - 1 AS VARCHAR(2)) + ' month '
+ CAST(DATEPART(DD, @variable_date) - 1 AS VARCHAR(2)) + ' day '``` Output when id =1 is used

Step 7: Check with different data when id = 2 –

```DECLARE @variable_date DATETIME = DATEADD(SECOND, (SELECT [value]
FROM [dbo].[inttodate] WHERE [id] = '2'), 0)

SELECT CAST(DATEPART(YEAR, @variable_date) - 1900 AS VARCHAR(10)) + ' year '
+ CAST(DATEPART(MONTH, @variable_date) - 1 AS VARCHAR(2)) + ' month '
+ CAST(DATEPART(DD, @variable_date) - 1 AS VARCHAR(2)) + ' day '``` Output when id = 2 is used

So we are getting desired output.
