I have a shopping cart which creates temporary tables in the format of
zorder_<phpsessionid>;
These tables are used to hold a customers order while they shop and
after checking out, it is dropped. The values of the shopping cart are
put together in an HTML table and stored as their history.
What I want to do is to run a cron job to delete the orders which were
left undone once a day at about midnight. Here is my current query

I have a linux server which is hosting several very large (~20GB)
databases. In order to save some disk space I dropped an index on one
of the larger (InnoDB) tables because it is no longer needed. It took
about 30 minutes for MySQL to drop the index, during which time I saw
the free disk space decrease. I didn't think anything of it while the
drop operation was running because I figured it was some kind of temp
file being used by the drop...

I have an archival process on a large database that runs once a month.
At the beginning of the process the triggers and indexes on the
tables whose data is moved are dropped, the data is moved and then the
triggers and indexes are recreated at the end. This produces a
massive improvement in performance.
The problem is the process is supposed to run on users accounts (thats
the way the front-end is set up) and they don't have the...

I just looked at a coworker's stored procedure and this person is
dropping 4 Foreign key constraints and then re-adding them after
processing the required logic (updating rows in the 4 tables in
question).
Is there *ANY* good reason to do this? What are the performance
implications of doing this - negative or otherwise?
I was furious when I found this because every once in a while I would
notice that the constraints would be in...

Need urgent help....
I wanted update one table which has a primary key and also has few
dependents.
I dropped Primary key before update sothat it won't affect the
dependent tables.
After dropping promary key, I could see many packages were invalid in
syscat.packages (VALID column).

ALTER TABLE DROP CONSTRAINT
;
Is this syntax correct?
The error I'm getting is:
Error Number 3199: Could not find reference.
I tried it without the curly braces, but no luck.

hi all!
I have a doubt regarding the dropping of a column.
As i've seen, we have an option like
"alter table <table namedrop column <column name>" in
oracle.
Do we have any method in db2 to drop a column?
Or is there any process for dropping a column in db2?
if so, please let me know.

We are getting deadlock errors (sporadically) on a batch job we've created.
This job runs against a SQL Server 2000 back-end.
The first step of the batch job is to run a DDL script to drop and create 4 tables that are used in the job. The tables are only used during this job and are not accessed by any other process or application.
The second step of the batch job is to make an OSQL call to run the stored procedures associated with...

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,...
