enter image description hereI'm learning to use taos JDBC in myBatis project, and when I using the demo provide by TDengine. I met this problem unable to establish connection.
sql:insert into db1.t1(ts,temperature) values (now,23.23)
The exception was thrown while calling on execute this sql command.
I tried to run the sql in command line on the server , it is ok.
while ran on my windows client it failed.
Running env
server: TDengine 2.1.3.2 on ubuntu 18.4
client: window x64
taos-jdbcdriver：2.0.32

I have tried this demo on my pc. it worked correctly.
unable to establish connection
this exception is always cause by network problem. but from you log info, it seemed that you can access to the TDengine.It is hard to say what caused this.
I advise that you can open the debug flag, and try to figure out what going on there.
you follow these steps to debug you TDengine and read the debug log
which normally is very useful.
for windows
{TDengine_home}/cfg/tao.cfg
add "debugFlag 135", Then run your demo code again and read your client log on
{TDengine_home}/log/taoslog.*
find your sql and you can find the error
The exception logs show that the error happened during statement.execute. You should have successfully created a connection object (e.g., createConnection).
at com.taosdata.jdbc.TSDBStatement.execute(TSDBStatement.java:85)
Did you use IP instead of hostname in your URL? Please use hostname since Tdengine latest versions require hostname. It may fail silently during creating connection and cause some weird problems.
Some other causes may be here in Tdengine FAQ.
2. When encoutered with the error " Unable to establish connection ", what can I do?
I have Spring boot 2 applications, when I am firing a select query, before actual query runs one validation query "SELECT 1" is being called because of DB pool wants to validate if the pooled connection is alive or not,
"Select 1" is also taking long time, what can be done to improve performance, of course disabling "Select 1" validation is not a good idea

Shouldn't it creates this column only that I added?

I have a 500 error in solR with this query :
q=*&wt=json&rows=0&fq=date:[2014-01-01T09:15:57.000Z/SECOND TO *]&facet=true&facet.field=text&facet.limit=5
I noticed that if put the parameter "facet.limit" to less than 5 it works but otherwise it does not. Here is the stack from SolR :
msg : "Error from server at http://localhost:8983/solr/core_replica1: Exception during facet.field: text"
trace : "org.apache.solr.client.solrj.impl.HttpSolrClient$RemoteSolrException:
Error from server at http://localhost:8983/solr/core_replica1: Exception during facet.field: text\n\tat
Do you know why this kind of error would happen?
I use Solr 6.6.0.
The field that I request is a org.apache.solr.schema.TextField that is :
Indexed | Tokenized | Stored | TermVector Stored | Store Offset With TermVector | Store Position With TermVector for the properties and shema
Thanks!
