Hello,
I would like to ask the about the following...
PostgreSQL allows tables resulting from subselects to be renamed with
an optional AS keyword whereas Oracle 9 will report an error whenever
a table is renamed with the AS keyword. Furthermore, in PostgreSQL
when the result of a subselect is referenced in an outer select
it is required that the subselect result be named, whereas this
is not true in Oracle. I wonder what standard SQL...

I have a performance problem with the following query and variations on the
subselect. The EXISTS version of the first example will complete in ~10
minutes. The NOT logic in both the examples makes them both keep running
long enough that a communications error is the only result returned so far.
This is a federated view computer ~160 k rows, computer_sys_id is PK .

Any suggestions on...

They are MysysAccessObjects;MysysACEs;MysisObjects and a number of other tables with Mysis

Hi,

successful migration I want to compare all tables. I have linked MySQL
tables through ODBC connection.
I want to create a report that compares all records between all tables in
both databases. I am looking for a report with differences in number of
records and differences in fields if 2 records are different. Probabaly it
can be acheived through query, but I...

Dear list,
Please let me know if this is not the list to ask this kind of question.
I am trying to optimize a query that joins two relatively large (750000 rows in
each) tables. If I do it using a subselect, I can "force" the planner to choose
the fastest path. Now, my question is:

Most JS people have seen sorttable.js and similar implementations.
I'm trying to do a SubSelect of an existing table, restricting values
in a Column to spec. range.
Rows manipulated through sorttable are not copies of the row objects,
they are ref's to the tbl row. Therefore care must be taken not to
delete them if they are needed, etc.
I'm getting used to the API:
tbody.deleteRow(rowIndex)

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,...

Hello
I'm a network technician in training and I need your help.
