Does ServiceNow support Schema on read with SQL like
SELECT CAST(order_amount AS INT)
FROM Order_table
We need to do type casting in memory where Order amount is stored as String in the database. Our goal is something like this which identifies the field type in memory
gr.addQuery('CAST(u_order_amount AS INT)', '>', 1000); //not exactly this syntax, this is just an example
Client wants to implement a Datalake table in ServiceNow with all the fields as string type or data is stored in a JSON field and while accessing for query and filerting, they wants to do casting for field type. Mapping between logical name of the field, backend name of the field and field type will be stored in the mapping table. Please let me know if field casting is passible in Servicenow in semantic layer without defining proper field types in the table?
