I need to select the first email in the list, but I don't know when it arrives.

Setting a large timeout for the email to arrive would probably work, but I am looking for a better solution.

I need to select the first row where the .subject is confirm your email address and the time field is a few seconds ago.

This is what I've tried:

I have a program which adds values to a database from textboxes.

I need to provide a way through which if the value added is not unique, it should return an error message. But my current code is unable to do that. Even if the value is not unique, it is saving the data in the database.

Below is my code.

I use the Roboto font in my React project and I have a strange problem, when I access my application locally the font is not applied to my texts, however if I open the element inspector and I uncheck and recheck a css property (no matter which one) the font is applied everywhere!

I use scss files with node-sass and my font is local and defined using @font-face

Here is the .scss file for the font

I am trying to insert multiple rows into my table using the below query : INSERT INTO TABLE2(ID) VALUES(1),(2) .It is showing SQL Command Not Ended.

Is it some syntacital error?I have rechecked but still not clear what's going wrong.

I have a Postgres table T with 3 columns (w1, w2, occurrences), all three are integers and w1 and w2 are referencing to another table. So basically, there are two foreign keys and a value.
There are about 15 million unique values (indices) that w1 and w2 can become in each row. Currently, T holds around 1.8 billion rows, which are more or less permutations of the indices with the limitation, that - if you think of a symmetric matrix - only one value pair may exist. For example, there may be (252, 13, x) but not (13, 252, x). However, there is no sorting, so (5, 900, x) also may be in T (sorting is done during insert and depends on the value in the referenced table). These tuples (w1, w2) are unique. At the moment, there are 3 different indices on that table, a UNIQUE INDEX tdc_idx_1 on T (w1, w2), a INDEX tdc_idx_w1 on T (w1) and a INDEX tdc_idx_w2 on T (w2).

Basically, I want to run two different queries. The difficulty for me is to figure out where the bad performance comes from, or to accept the runtime given the "complexity" of the query and the table size (I'll guess that is not the case..). Short, I could need help in the structure of the queries and probably the handling of the table indices (or maybe the table design in general).
The most straightforward query for my desired result is

Whenever I login to my app this is what it says, and my user profile does not get my details. I rechecked everything but cant seem to find the problem. I am still learning MERN and I am stuck here for a few days.

This is my User Model:

As I understood by reading this blog post, Bitmap index scan may be superior to index scan, since it batches access to pages of the table itself to fetch data that is not present in the index.

Yet, it still needs to traverse index, so I see no reason why it may be better than Index-Only scan when all data requested present in index. Yet it looks like in many cases Postgres prefers bitmap index scan to index-only.

Taking example from another blog post:

I have this sample code:

I am currently trying to migrate a system to postgres and I am unfortunately not able to understand why a specific query is running so incredibly slow. Both in Transact-SQL and Oracle the same query runs in under 200ms. First things first though, I have a big table with 14.000.000 entries currently which only gets bigger and bigger. Furthermore the table itself has 54 columns meaning that we have quite the sum of data.

The table has a rather straight forward structure like this:
