Class ProjectionPolicy

java.lang.Object

dev.frostlake.metastore.SqlObject

dev.frostlake.metastore.model.ProjectionPolicy

All Implemented Interfaces:

Taggable

public class ProjectionPolicy
extends SqlObject

Snowflake PROJECTION POLICY — attached to a COLUMN, it decides whether that column may appear in a query's select list at all. Unlike a masking policy, which rewrites the value, this one refuses the projection outright; the column stays usable everywhere it is not projected (a WHERE, an ORDER BY, an aggregate over it), all live-verified.

The policy takes no arguments — live refuses a signature with any — and its body evaluates to a PROJECTION_CONSTRAINT(ALLOW => …), so a conditional body is just an expression choosing between two of them.
