Hi,

Im using elasticsearch input plugin to obtain info from elastic, with this extracted info i use the JDBC streaming plugin to get information from BD with some fields that i extracted from elastic.  
The problem that I have is that the statement to execute changes depending on the value that i extract from Elastic.  
Is there any way to define a variable statement either through a variable that takes a value according to some condition?

For example, if I extract from elastic the variable A with value B  
the query would be

SELECT \* FROM  
TABLE Y WHERE NAME = 'B'

On the other hand, if I extract the variable B with value C, the query would be

SELECT \* FROM TABLE Z,Y WHERE CITY = 'C'

Best regards,

---
