This depends on your RDBMS choice.
In MySQL, you can determine the number of connections using the SHOW PROCESSES; command.
In Oracle, you run this query:
SELECT s.username AS username, (
CASE
WHEN grouping(s.machine) = 1
THEN '**** All Machines ****'
ELSE s.machine
END) AS machine,
COUNT(*) AS session_count
FROM v$session s,
v$process p
WHERE s.paddr = p.addr
AND s.username IS NOT NULL
GROUP BY rollup (s.username, s.machine)
ORDER BY s.username,
s.machine;

How many connections are required by a fully-connected network with five stations?
A fully connected network follows the formula c=n*(n-1)/2, where n is the number of nodes and c is the number of connections. So, for a network of 5 nodes (stations) there would be 5*4/2=10 connections.
How many fields are in the database?
The number of fields in a database can vary widely depending on its design and purpose. Typically, a database table may have anywhere from a few fields to several dozen, depending on the complexity of the data being stored. To determine the exact number of fields in a specific database, one would need to examine its schema or structure directly.
How do I find a license plate number if you have the owners name and address?
Consider going to the owner's address and observing the number yourself or hiring a private investigator to do the same. A private investigator might also have database access or law enforcement connections to obtain the required information from a database.
How can you determine if a cat has a microchip?
To determine if a cat has a microchip, a veterinarian or animal shelter can use a handheld scanner that reads the microchip's unique identification number. This number can then be checked against a database to find the cat's owner's contact information.
How can I determine if bank account numbers are unique?
To determine if bank account numbers are unique, you can compare each account number to all existing account numbers in the database. If there are no duplicates, then the account numbers are unique.
How can we determine the number of cycles in a graph?
To determine the number of cycles in a graph, you can use the concept of Euler's formula, which states that for a connected graph with V vertices, E edges, and F faces, the formula is V - E F 2. By calculating the number of vertices, edges, and faces in the graph, you can determine the number of cycles present.
How many jaynes are there in the world?
It is difficult to accurately determine the total number of individuals named Jayne in the world as there is no centralized database for first names. This number would likely vary by region and population size.
Compare 4 connected and 8 connected method for polygon filling?
In polygon filling, the 4-connected method uses only the four orthogonal neighbors (up, down, left, right) to determine the fill area, while the 8-connected method includes all eight surrounding pixels (adding the diagonals). The 4-connected method can lead to gaps in the fill if diagonal connections are required, whereas the 8-connected method provides a more complete fill by allowing diagonal adjacency. Consequently, the 8-connected approach is often preferred for more complex shapes or when a seamless fill is desired. However, the 8-connected method may require more processing due to the increased number of neighboring pixels to check.
What are connections between the number 16 and the world?
There are no specific connections.
How do you determine the year of a Tag Huer watch?
You can determine the year of a Tag Heuer watch by locating the serial number on the watch. The serial number can usually be found on the back of the watch case or on the paperwork that came with the watch.

What year is a Kubota m8200 with serial number 51721?
To determine the year of a Kubota M8200 with serial number 51721, you would typically refer to the manufacturer's serial number identification system or database. Generally, Kubota tractors have a production year that can be identified by the serial number. However, without access to that specific database, I can't provide the exact year. It's recommended to contact a Kubota dealer or check the owner's manual for accurate information.
