Splunk dbxquery merge with splunk search - sql

Question

I am trying to merge Splunk search query with a database query result set. Basically I have a Splunk dbxquery 1 which returns userid and email from database as follows for a particualr user id:
| dbxquery connection="CMDB009" query="SELECT dra.value, z.email FROM DRES_PRINTABLE z, DRES.CREDENTIAL bc, DRES.CRATTR dra WHERE z.userid = bc.drid AND z.drid = dra.dredid AND dra.value in ('xy67383') "
Above query outputs
VALUE EMAIL
xv67383 xyz#test.com
Another query is a Splunk query 2 that provides the user ids as follows:
index=index1 (host=xyz OR host=ABC) earliest=-20m#m
| rex field=_raw "samlToken\=(?>user>.+?):"
| join type=outer usetime=true earlier=true username,host,user
[search index=index1 source="/logs/occurences.log" SERVER_SERVER_CONNECT NOT AMP earliest=#w0
| rex field=_raw "Origusername\((?>username>.+?)\)"
| rex field=username"^(?<user>,+?)\:"
| rename _time as epoch1]
| "stats count by user | sort -count | table user
This above query 2 returns a column called user but not email.
What I want to do is add a column called email from splunk dbxquery 1 for all matching rows by userid in output of query 1. Basically want to add email as additional field for each user returned in query 2.
What I tried so far is this but it does not give me any results. Any help would be appreciated.
index=index1 (host=xyz OR host=ABC) earliest=-20m#m
| rex field=_raw "samlToken\=(?>user>.+?):"
| join type=outer usetime=true earlier=true username,host,user
[search index=index1 source="/logs/occurences.log" SERVER_SERVER_CONNECT NOT AMP earliest=#w0
| rex field=_raw "Origusername\((?>username>.+?)\)"
| rex field=username"^(?<user>,+?)\:"
| rename _time as epoch1]
| "stats count by user | sort -count
| table user
| map search="| | dbxquery connection=\"CMDB009\" query=\"SELECT dra.value, z.email FROM DRES_PRINTABLE z, DRES.CREDENTIAL bc, DRES.CRATTR dra WHERE z.userid = bc.drid AND z.drid = dra.dredid AND dra.value in ('$user'):\""

Answer 1

Replace $user with $user$ in the map command. Splunk uses a $ on each end of a token.
The username field is not available at the end of the query because the stats command stripped it out. The only fields available after stats are the ones mentioned in the command (user and count in this case). To make the username field available, add it to the stats command. That may, however, change your results.
| rex field=_raw "samlToken\=(?<user>.+?):"
| join type=outer usetime=true earlier=true username,host,user
[search index=index1 source="/logs/occurences.log" SERVER_SERVER_CONNECT NOT AMP earliest=#w0
| rex field=_raw "Origusername\((?<username>.+?)\)"
| rex field=username"^(?<user>,+?)\:"
| rename _time as epoch1]
| stats count by user, username | sort -count
| table user, username
| map search="| dbxquery connection=\"CMDB009\" query=\"SELECT dra.value, z.email FROM DRES_PRINTABLE z, DRES.CREDENTIAL bc, DRES.CRATTR dra WHERE z.userid = bc.drid AND z.drid = dra.dredid AND dra.value in ('$user'):\""```
