Issues with object/column name "primary" in Query JSON with SQL

Does anyone have an idea why I'm getting errors around trying to query on the column "primary" in the following data set?

Example data set from allServers:

[
  {
    "id": 313,
    "hostname": "hostname1",
    "serverType": "AS",
    "primary": true,
    "environmentType": "PROD"
  },
  {
    "id": 785,
    "hostname": "hostname2",
    "serverType": "XSP",
    "primary": false,
    "environmentType": "PROD"
  }
]

Query of the Resource "Query JSON with SQL":

SELECT * FROM {{allServers.data}} as stuff
WHERE stuff.serverType = 'AS' 
  AND stuff.primary = 'true'

The error shown when the query is run with "Preview":

message:"Parse error on line 3:
...= 'AS'   AND stuff.primary = 'true'
----------------------^
Expecting 'LITERAL', 'BRALITERAL', 'VALUE', 'STAR', got 'PRIMARY'"

Many thanks!

I was able to figure it out with help from our internal team - "primary" is a reserved word, so it needs special treatment, e.g.

SELECT * FROM {{allServers.data}} as stuff
WHERE stuff.serverType = 'AS' 
  AND stuff.[primary]
