I'm on a hosted Linux server and I have an Outer Join query that's returning
on one less row than I expect. There are two rows very similar and I
expect them both returned. There are similar other cases of rows all being
returned.
I've googled: debug mysql query
I've searched on mysql.com for 'debug'
Alot comes up but all relates to queries returning errors. My query happily
returns with one row too little out of 100 rows.

I have a view that will return say 5000 records when I do a simple
select query on that view like.
select *
from vw_test_view
How can I set up my query to only return a certain # of records, say
the first 300?

it is using a sequential scan. Details are below:

Hi,
I have a sql server database with 1.7 million records in a table, with
about 30 fields
When I run select * from tablename it can take over 5 minutes.
How can I get this time down or is it normal?
Thanks

this is a slight change to a fequently asked question around here. I
have a table which contains a "sortorder" column where a user can
specify some arbitrary order for records to be displayed in. Users
have sometimes ordered records the way we used to number lines in a
BASIC program (10,20,30, etc.). I'd like to do an update query and fix
this so that every record is in sequential order. I found an example
in this newsgroup of how to...

Hi,
I am trying to implement an MD5 checksum function using an UDF call to
C wrapper returning the MD5 checksum. I've downloaded a free (LGPL)
implementation in C of the MD5 algorithm from
http://xyssl.org/code/source/md5/. With help from our friends over at
comp.lang.c, I've managed to compile, link and run the code. However,
when I call it from DB2, I can invoke it once only.
I suspect the error has to do with freeing of memory,...

Hi
I have a chunky bit of sql that I will want to call from a number of
places. It will return a
few thousand rows. Whats the best way of structuring this?
1) I initially thought of using nested stored procedures and returning
the result in a temporary
table. However the scope of the temporary table seems to be limited to
the stored procedure

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,...
