Description

Attempting to use bitwise math operation in a TICKSript fails with,
**Error:**
failed to parse InfluxQL query: found &, expected FROM at line 1, char 30

**TICKScript:**
var data = batch
|query(''' SELECT last("StatusWrd") & 8 FROM "monitoring"."autogen"."modbus" WHERE ("host" = 'host-002') ''')
.period(10s)
.every(10s)

**Same query works when run in influxdb:**
SELECT last("StatusWrd") & 8 FROM "monitoring"."autogen"."modbus" WHERE ("host" = 'host-002')

Research direction

Start with Kapacitor's batch query handling and the TICKScript path that passes the embedded InfluxQL to the parser. Reproduce the query containing the bitwise '&' operator and compare it with the working InfluxDB query; done means the TICKScript batch query parses and executes successfully.
