Class RowAccessPolicyAttachment

java.lang.Object

dev.frostlake.executor.commands.RowAccessPolicyAttachment

public final class RowAccessPolicyAttachment
extends Object

The checks a row access policy attachment must pass, shared by the ALTER form and the CREATE TABLE / CREATE VIEW clauses — live makes the same ones wherever the attachment is written, with a single measured difference: an unknown column is an invalid identifier on the ALTER path and a column 'X' does not exist at CREATE, so the caller reports that one.

Method Summary

Method Details

require

public static RowAccessPolicy require(Catalog catalog,
 String policyName)

The policy a name resolves to, refused when it resolves to nothing.

Parameters:

catalog - the catalog to resolve in

policyName - the policy name as written

check

public static void check(RowAccessPolicy policy,
 Table table,
 String objectName,
 String policyName,
 List<String> columns)

The argument-count, masked-column and type checks, in live's order. The columns must already be known to exist — resolving them is the caller's job, because the two paths word that refusal differently.
