Unable to perform sql select on logstash index

[hemanth22 (Hemanth B)]

Hello team,

I have below indexes in the kibana when searched with below query.

GET /_xpack/sql?format=txt
{
    "query": "SHOW tables"
}

Output:

              name               |     type      
---------------------------------+---------------
.kibana                          |ALIAS          
.kibana_1                        |BASE TABLE     
.monitoring-es-6-2019.03.17      |BASE TABLE     
.monitoring-kibana-6-2019.03.17  |BASE TABLE     
.monitoring-logstash-6-2019.03.17|BASE TABLE     
bank                             |BASE TABLE     
logstash-2015.05.18              |BASE TABLE

logstash-2015.05.20              |BASE TABLE     

When trying to search logstash table getting error as below.

GET _xpack/sql?format=txt
{
  "query": "select * from logstash-2015.05.18"
}

Error Output

Can you please check and advice.

Thanks,

Hi @hemanth22,
You just need to escape the index name because - is a reserved character (the minus sign):

GET _xpack/sql?format=txt
{
  "query": "select * \"from logstash-2015.05.18\""
}
