Sqlite choose only previous day data?

[questuk]

Hi,

I have a Sqlite database eventually I want to show the last 1 days data on a chart.
But first I need to sort the date. Today as I write this it is Friday.

I have the following ..
SELECT *
FROM DATA
WHERE ID LIKE 'Speedfit - Temperature'
ORDER BY Unix_Time,datetime ('now','-1 day');

I want too only have data for Friday (today), but i get all my data of 859 readings from weeks ago ?

Where am I going wrong, I have spent 2 hours on the internet but cannot find the answer.

Thanks

You have to put the condition on the date in the Where clause, not in the Order By clause. That is logical because you want to select records Where the date is today.

maybe the following works for you:

SELECT *
FROM DATA
WHERE  DATE(Unix_Time, 'unixepoch') = DATE('now','-1 day');

or for 24hs...

SELECT *
FROM DATA
WHERE "Unix_Time" >= date('now', '-1 days') AND "Unix_Time" < date('now');

for situations like this, I find it best to get queries working outside of node-red & when you have a working query, transpose it into your flow.

Thanks guys for your help

It is now working in NodeRed,
For anyone reading this in the future. I have included a version that you would use as a query in an actual Sqlite editor. And the same code but formatted to work in NodeRed.

This works as a query in a Sqlite editor

SELECT *
FROM DATA
WHERE ID LIKE 'Speedfit - Humidity'
AND DATE(Unix_Time, 'unixepoch') >= DATE('now','-1 day');

Also here it is formatted to work in NodeRed ( you can cut and paste )

msg.topic =

" SELECT * FROM DATA WHERE ID LIKE "  +
" 'Speedfit - Humidity' "             +
" AND DATE (Unix_Time, 'unixepoch') >= DATE ( 'now' , '-1 days' )";

return msg;

@questuk you can also format sql queries easily using the `templates node. Give it a try

[questuk]

Hi again,

How would I format that in a template node, I have tried many ways but keep getting ...
Error: SQLITE_ERROR: unrecognized token: "{"

I have removed the + from the original, is this correct ?

One way i tried ...

   SELECT * FROM DATA 

      {   WHERE ID LIKE
         'Garage - Humidity'
          AND DATE (Unix_Time, 'unixepoch') >= DATE ( 'now' , '-2 days' );
      }

return msg;

Here is a set of examples using sqlite with the sql statements built in a template node
