Hi,
I've got what I think (probably incorrectly) should be a simple SELECT :
Two colums with data like
col1 col2
1 50
1 51
2 50

Example, suppose you have these 2 tables
(NOTE: My example is totally different, but I'm simply trying to setup
the a simpler version, so excuse the bad design; not the point here)
CarsSold {
CarsSoldID int (primary key)
MonthID int
DealershipID int

I have a table with a varchar(255) column, it has 111,000 rows. When I do a
select distinct on that column it takes 16 seconds and returns about 25
distinct values, I'd like it to take much less time. I tried creating an
index but the explain on the query shows that it isn't using an index. Is
there any way to speed this up or should I just maintain another table with
the distinct values myself?

Hi,
I'm currently learning the ropes with CSS, PHP, MYSQL, Javascript etc...
by redesigning my website as a database driven site.
Okay, so I'm skilled at perl, data manipulation and data analysis and
I've done a fair bit of (non CSS) HTML in the past and know what a
relational database is. However, I'm having problems trying to formulate
a particular MYSQL query (maybe I just don't know the lingo or maybe

The select statements return different data for
most_commons_vals depending on whether n_distinct is
included in the select clause or not.
I only seem to get the behavior below against int8
columns - but I haven't interated through every
conceivable data type either.
Is this expected behavior or perhaps a bug?

People are telling me it is bad to put
select * from <atable>
in a view. I better should list all fields of the table inside the
definition of the view.
I dont know exactly why but some say:
A select * from makes sql server does a table scan.

Hi,
I have a web application with a table to store terms and
conditions of a Company.
This may some times run into many pages and some times it may be just a
few sentences. It is a character text field. I want to know which Data
type I need to use so that it doesnt waste memory.
thanks in advance,

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention.
