postgresql - How to get the local port of a jdbc connection? -

-

As far as I know that more than one connection objects through JDBC If the database is installed in the database, then each connection places a separate port on the machine where connection is installed (they all connect to a port on the server, where DBMS is running).

I tried to remove the port. Connection corresponds to the objects. Unfortunately I have not found any way to do this.

Background: I am doing performance analysis where I establish several clients who issue questions on DB. I am logging the execution time of the query on the database server. I have the resultant log - between others - information about connections, who started the query, e.g. localhost.localdomain: 44760 I hope that this information can be used to map the customer to each query or for a more accurate connection object, (Which is my final goal and works in the analysis objectives).

Simply select through this JDBC connection: 

  inet_client_port () Select

in more ways like this:

javascript - data.match(var) not working it seems -

OK, I have this small block code, which is to scanned a number on the website, but for some reason There is a hip that it is not scanning at all. var regenges = / \ & lt; Span class = "currency-robux" data-to-"item-private-value-price" & gt; ([\ D,]) \ & LT; \ / Span \ & gt; /; Var ValueCiling = Data. Match (reggae); Value-song = number (value slicing location (",", "")); Is there anything wrong with that? This is related to the if statement if (value sling and lieutenant; = price watching) { < P> A function calls to move from there, but for some reason it does not seem to run at all. So I think the Regex is wrong but I'm not sure how. (There is a variable in PriceWinking , this is a snippet from the code.) On the website, I'm trying to remove it. & lt; Span class = "robux" data-plus = "item-privatesale-price" & gt; 115 & lt; / Span & gt; Keep in mind
