Hi,
In a client-server interaction with BaseX database, I see the ClientSession object is not associated with a database, in the usual manner(Usually, a session is established with a particular database at session creation time). Please let me know if my understanding is right:
When we I do the following:
*Line 1*: ClientSession session = new ClientSession("localhost", 1984, "admin", "admin");
*Line 2*: session.execute("OPEN databaseA");
*Line 3*: session.execute("XQUERY <some xquery>");
*Does "Line 2" bind the session with databaseA?(*So, I am assured that Line 3 executes on databaseA?)
Thanks and regards,
Swaminathan Sahiram

Hi Swaminathan,
yes you're right. The ClientSession object is just associated with a database after you executed the "open database" command.
You can access all databases (without opening them) with the 'doc' function of xquery.

This would be bad, if you want to have the chance to open and close databases without recreating your session.
Kind regards,
Andreas

Written for BaseX 6. BaseX may have changed since: please check the current documentation.
