COUNT many but display just once?

Hi, I have a table that I insert a member's country into every time
someone signs up. What I'd like to do is pull information from the DB
such that I can see each country and the number of users from each.
For example:

Argentina 10
Brazil 5
Canada 3

I'm having trouble writing the SQL for this...any suggestions?

Thanks,

Erik

W/o schema it's impossible to say what you want for sure but something like
create table membership
(
country varchar(20),
signup varchar(20)
);

insert into membership values ('Argentina', 'member 1')
insert into membership values ('Argentina', 'member 2')
insert into membership values ('Brazil', 'member 1')
insert into membership values ('Brazil', 'member 1')
insert into membership values ('Brazil', 'member 2')
insert into membership values ('Brazil', 'member 3')
insert into membership values ('Canada', 'member 1')

select country, count(signup) from membership group by country
SELECT COUNTRY, COUNT(signup) from membership group by country

Hi all. I'm trying to write a program that: 1) Ask me what file I want to count number of lines in, and then counts the lines and writes the answear out. 2) I made the first part like this: in_file = raw_input("What is the name of the file you want to open: ") in_file = open("test.txt","r")

Hello Access Developers, I'd like to know if it is possible to perform a count in an expression that defines a control source. My report is based on a query. In my report, I want a text box to display the number of times a certain value appears in a certain field (i.e. perform a ‘count'). I will be doing this for many values in many fields so do not wish to have scores of queries to build my report.

I have a timer on a form. It isn't firing at all. I know that the timer is enabled, and that the interval is low (4000, which should be 4 seconds). To ensure the timer wasn't being inadvertantly reset I put some extra code in the subs that enable and disable the timer. They fire as expected. To test this I added a second timer with a 1 second interval. The event for this time would output the enabled status of the first timer and its...

A SQL Server 2005 stored procedure expects a parameter 'UserID' depending upon which it retrieves the no. of records & OrderIDs corresponding to the 'UserID' from a DB table (note that OrderID & UserID are two of the columns in the DB table). So for e.g. consider a user whose UserID=6 & the DB table has 3 records whose UserID=6. In other words, there are 3 OrderID records of the user whose UserID=6, say, OrderID=8, OrderID=17 & OrderID=29....

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own.... Now, this would greatly impact the work of software developers. The idea...
