QUESTION
I have an SQL query as follows
...ANSWER
Answered 2020-Dec-24 at 15:44Your syntax looks like SQL Server.
Assuming that the IP address is stored as a string, then SQL Server offers a very bespoke function called parsename()
which basically does what you want:
QUESTION
Consider the following VersionClass
. Assume that the FRTDB has a node matching this model.
When the firebase android library tries to serialize or deserialize the class (getValue(VersionClass.class)
or setValue(new VersionClass())
):
- Will it only use the accessor methods (e.g.
getVersionCode(), setVersionCode(int versionCode)
)?
Or search for exact property names in my class (e.g.versionCode
)? - If I keep the accessor method names unchanged, and change the variable names, (e.g.
versionCode
toanotherNameForVersion
, butgetVersionCode(), setVersionCode(int versionCode)
names are untouched) will the code fail?

It can use eithe rone. But you might have to make the property public if you want to use that instead of the setter. This should be easy enough for you to try for yourself.
If I keep the accessor method names unchanged, and change the variable names, (e.g. versionCode to anotherNameForVersion, but getVersionCode(), setVersionCode(int versionCode) names are untouched) will the code fail?
No, it will not fail. It will use the getter methods that match, according to the JavaBeans spec. This also should be easy for you to test for yourself by simply making the change, recompiling your app, and running it.
If you need to map a child value to a java bean, and the names, don't match, you can use the @PropertyName annotation to help it match properties or getters.
QUESTION
Slowly progressing with my learning with Python and would love a little hand with some code I've tried to create.
I previously had this program running with Global Variables to get a proof of concept to learn about passing variables between functions. Fully worked fine. However, rather than running the function and returning to the menu, it will just stop where I return the value and not progress back to the main menu I created. It is at the point of "return AirportDetailsGlobal".
I'm sure its a simple one, and as said - still learning! Really appreciate any help on this!

...ANSWER
Answered 2020-Jul-13 at 15:06If you do a return
then your code goes back to where it was called from. If it wasn't called from anywhere (ie. you just ran that script directly) then calling return
is in most ways equivalent to calling sys.exit()
, ie. the program terminates. It'll never hit your break, leave the loop, or hit your call to menu()
.
Also, your indentation as given there isn't right, the else
is at the same level as the for
, not the if
. I don't think that's the problem but you might hit it next. ;-)
QUESTION
I've been trying to connect to Snowflake using the ODBC driver via a proxy but have so far been unable to. I'm using HAProxy to do this.
This is from odbc.ini
, where I've configured my DSN:
ANSWER
Answered 2020-Feb-03 at 02:29Because of the requirement for SSL pass-through to be configured on the proxy, HAProxy might be difficult if not impossible to configure and use as a forwarding proxy for Snowflake's ODBC driver.
The reason is stated in this SO answer:
I captured packets , using proxy to visit a https website , curl will start a HTTP CONNECT method to establish a tunnel. The tunnel should be between curl client and proxy, but TCP proxy will delivery all messages to web server, so web server will reset the connection.
A forward proxy should not just delivery messages between client and web server.It should understand the HTTP CONNECT method
HAProxy when doing SSL pass-through behaves as a TCP proxy, and so does not parse the underlying messages. However it needs to first set up the tunnel before doing so and that requires responding to the HTTP CONNECT
method.
QUESTION
Hi everyone in acumatica development,
i just want to ask how to save and make action button fucntion on a custom form so i have a custom form production schedule in acumatica that i created.
then i created a custom table from mssql then provide all class on my custom form here is my table from acumatica
...ANSWER
Answered 2019-Nov-08 at 13:41You should update the [PXDBInt(IsKey = true)] to [PXDBIdentity] as you also have Prodnumber as a key and have a selector control on the page. I am assuming this would require users to enter the Prodnumber field and search by it, which may be different than the autonumber key.
I would attach a PXSelector attribute to the Prodnumber field if this is the case. You can add the following to search for Prodnumber but also show other fields, like the dates and description:
QUESTION
My shell script executes a SQL to fetch the data in the following format:
...ANSWER
Answered 2019-May-01 at 05:10The $email_configs
array is not being set correctly. It's using spaces as the array delimiters, not newlines.
Rather than set an array, read the output of sqlplus
in a loop.
