Hi,

you store in your persistent table login (user_name) it is presistent information.
You join your persistent table which should contain login name and you join your persistent table with mon$attachment an you know who is currently logged in.

once again sample

CREATE TABLE MY_USERS
(USER_ID INTEGER NOT NULL PRIMARY KEY,
NAME VARCHAR(32) NOT NULL,
AGE INTEGER,
...
LOGIN_NAME VARCHAR(32) NOT NULL
);

sample record
USER_ID=1
NAME=’Karlos’
AGE=52
..
LOGIN_NAME=’SYSDBA’


and you run sql

SELECT * FROM MY_TABLE MT INNER JOIN MON$ATTACHEMNTS A ON A.MON$USER=MT.LOGIN_NAME

Hi,

I have a table of users, but I wouldn't store in persistent table a volatile information (if it was possible).


The link between a connection id and user id isn't a persistent information (like connections,transaction ecc...)

Hi,

what do you mean by maintain here? Do you have custom user information table or not? If not then what do you need to store in this context var?

I supposed that you have custom user information table and you need to match your user record with server user to know who is logged into the server.
