Hi,
I am new to mysql and need help on how to join tables. I have a database
which contains 4 tables, the main table contains information by date order
and the other 3 contain data also in date order. So I need to write a
query that retrieves all the information for one record, lets say I want to
query on the main table any entry that is for the 2004-01-06 and this date
is also in a field called 'Date' in the other tables, how do I go...

Hello,
We are developing an application against an MS SQL Server 2000 database
which requires that we implement full-text searching across columns in
multiple tables. The research that we have conducted seems to indicate
that this is not directly possible within SQL Server 2000. And we can
find no way to implement this as the catalogs that are generated are
table specific.
As a work-around, we are planning to create a secondary...

I have a parent table `products` that contains all company products.
The product details are divided amongst 4-5 product details child tables
such as `paper`, `pens`, `books`, `sets`, `pens_paper`.
The 'product_ids` may be in one or more of these child tables but always in `products`.
Is a single DELETE query possible that will delete all occurences of a `product_id` in the tables where the `product_id` occurs.

Is it possible in a single query to search up to 12 tables for a similar text string and count the number each time a duplicate is found?
I have a table for each month with a string field that contains a referer string.
table = stats_2007_01
table = stats_2007_02
table = stats_2007_03 and so on....
field = string (200)
I can query a single table and return the result i expect with this statement

This is a bit hard to explain but I'll try my best.
I have 2 tables. One table has a row with the following value:
2,3
The two numbers are both ID's that are in the second table. I need to write a query that will ultimately give me the values of the second table, merged together as follows:
Data One, Data Two

I've interacted with SQL DBs for years in project/product management roles, although admittedly still a newbie when it comes to actually building and manipulating things within SQL directly. I've inherited a project and have spent hours trying to figure something by browsing through user docs and other posts and trying things but am still stumped - hence me calling in the experts! :)
What I am trying to finish building seemed like it would...

Im designing a hazard log tool. I have a main form containing hazards, subform for consequences and subform for actions.
I have a form for comments, and I want to reuse that as subform for hazards, consequences and actions, such that you can comment on either of the three.
What would be a good way to go about this?
What table setup should I go for? Should I for example make 3 secondary key fields in the Comments table, 1 for hazards, 1...

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...

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

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