Mike Jumper updated GUACAMOLE-1253:
-----------------------------------
Description:
We have a large user count ~1500 and use SQL Server. When trying to load the
user settings on the web interface the page will never load and we get this
error:
{code:none}
SELECT [guacamole_user].user_id, [guacamole_entity].entity_id,
[guacamole_entity].name, password_hash, password_salt, password_date, disabled,
expired, access_window_start, access_window_end, valid_from, valid_until,
timezone, full_name, email_address, organization, organizational_role, ( SELECT
MAX(start_date) FROM [guacamole_user_history] WHERE
[guacamole_user_history].user_id = [guacamole_user].user_id ) AS last_active
FROM [guacamole_user] JOIN [guacamole_entity] ON [guacamole_user].entity_id
[guacamole_entity].entity_id WHERE [guacamole_entity].name IN ( ? , ? , ?
,.......... ? ) AND [guacamole_entity].type = 'USER'; SELECT
[guacamole_user_attribute].user_id [guacamole_user_attribute].attribute_name,
[guacamole_user_attribute].attribute_value FROM [guacamole_user_attribute] JOIN
[guacamole_user] ON [guacamole_user].user_id
[guacamole_user_attribute].user_id JOIN [guacamole_entity] ON
[guacamole_user].entity_id = [guacamole_entity].entity_id WHERE
[guacamole_entity].name IN ( ? , ? ,........ ? ) AND [guacamole_entity].type =
'USER';
### Cause: com.microsoft.sqlserver.jdbc.SQLServerException: The incoming
request has too many parameters. The server supports a maximum of 2100
parameters. Reduce the number of parameters and resend the request.
{code}
I truncated the name IN statement as there was a "?" for each of the 1500 users
two times in the select statement.
