Mike Jumper updated GUACAMOLE-1796:
-----------------------------------
Priority: Minor (was: Major)
> Default batch size for SQL Server is too large
> ----------------------------------------------
>
> Key: GUACAMOLE-1796
> URL: https://issues.apache.org/jira/browse/GUACAMOLE-1796
> Project: Guacamole
> Issue Type: Bug
> Components: guacamole-auth-jdbc-sqlserver
> Affects Versions: 1.5.2
> Environment: docker
> Reporter: Chris Johnson
> Priority: Minor
> Attachments: guacamole-client.log
>
>
> We have a rather large number of connections and after logging in, I'm
> getting "An error occurred and this action cannot be completed".
> In the Guacamole log I'm getting the following error:
> {quote}^### Error querying database. 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.^
> ^### The error may exist in
> org/apache/guacamole/auth/jdbc/connection/ConnectionMapper.xml^
> ^### The error may involve defaultParameterMap^
> ^### The error occurred while setting parameters^
> ^### SQL: SELECT [guacamole_connection].connection_id,
> [guacamole_connection].connection_name, parent_id,
> protocol, max_connections, max_connections_per_user,
> proxy_hostname, proxy_port,
> proxy_encryption_method, connection_weight,
> failover_only, ( SELECT MAX(start_date)
> FROM [guacamole_connection_history] WHERE
> [guacamole_connection_history].connection_id =
> [guacamole_connection].connection_id ) AS last_active
> FROM [guacamole_connection] WHERE
> [guacamole_connection].connection_id IN << A load of question marks >> ###
> Cause: com.microsoft.sqlserver.jdbc.SQLServerException: The incoming request

> {quote}
> I believe that there was a similar issue that was fixed in GUACAMOLE-1253 but
> for the number of users.
> I have attached the log if that helps.
> At the moment, the platform is unusable for ourselves.
