SQL query to find the previous date, current date and next date

Question

If the current date is 3/12/2015, then I need to get the files from dates 2/12/2015, 3/12/2015, 4/12/2015. Can anyone tell me an idea for how to do it?

<%
try
{
Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");


Connection con = DriverManager.getConnection("jdbc:sqlserver://localhost:1433/CubeHomeTrans","sa","softex");

Statement statement = con.createStatement() ; 

ResultSet resultset = statement.executeQuery("

select file from tablename
where date >= DATEADD(day, -1, convert(date, GETDATE()))
and date <= DATEADD(day, +1, convert(date, GETDATE()))") ;


while(resultset.next())
{
String datee =resultset.getString("Date");
out.println(datee);
}
}
catch(SQLException ex){
System.out.println("exception--"+ex);

}

%>

This is the query I have done, but it's erroneous. I need to get the previous date, current date and next date.

Answer 1

Use DATE_ADD() And DATE_SUB() functions:

Try this:

SELECT FILE, DATE
FROM ForgeRock
WHERE STR_TO_DATE(DATE, '%d/%m/%Y') >= DATE_SUB(CURRENT_DATE(), INTERVAL 1 DAY)
  AND STR_TO_DATE(DATE, '%d/%m/%Y') <= DATE_ADD(CURRENT_DATE(), INTERVAL 1 DAY);

Check the SQL FIDDLE DEMO

::OUTPUT::

| file |       DATE |
|------|------------|
|  dda | 31/12/2015 |
|  ass | 01/01/2016 |
|  sde | 02/01/2016 |

Answer 2

You can use dateAdd function

syntax

DATEADD(datepart,number,date)

ie for current date

select GETDATE()

for yesterday

select DATEADD(D,-1,GETDATE())

for tomorrow

select DATEADD(D,1,GETDATE())

so, your query should be like

select file from tablename
where date >= DATEADD(D,-1,GETDATE())
and date <= DATEADD(D,1,GETDATE())

Answer 3

Simplest way to get all these dates are as below:-

CURRENT DATE

SELECT DATEADD(day, DATEDIFF(day, 0, GETDATE()), 0)

NEXT DAY DATE (Adding 1 to the dateadd parameter for one day ahead)

SELECT DATEADD(day, DATEDIFF(day, 0, GETDATE()), 1)

YESTERDAY DATE (Removing 1 from the datediff parameter for one day back)

SELECT DATEADD(day, DATEDIFF(day, 1, GETDATE()), 0) 

If you go through the link here , you will get an amazing way of explanation for getting date . It will clear your logic and will be useful for future reference too.

Hope that helps you

Answer 4

current date

date = (SELECT CONVERT(char(10), GetDate(),126))

yesterday

date = (SELECT dateadd(day,datediff(day,1,GETDATE()),0))

next day

date= SELECT DATEADD(day, 1,(convert(date, GETDATE())))
