Enabling camelcase will transform any snake case field names coming from the database into camel case ones

Ex: SELECT 1 AS my_field will return { myField: 1 }

This won't have any effect if you explicitly set the field names with the fields parameter

This parameter supersedes query column names coming from the databases in the order they were provided. Fields must be unique and be in the range of (a-zA-Z0-9_), otherwise the query will throw before execution. A field can not start with a number, just like JavaScript variables

This setting overrides the camelcase option

Ex: SELECT 'A', 'B' AS my_field with fields ["field_1", "field_2"] will return { field_1: "A", field_2: "B" }
