Hello, All.
I'm working on controlling of replication using SQL and get stuck on "alter table"
statement. It may include zero or more clauses that require modification of RDB$RELATIONS
table. For example: "alter table t drop sql security, disable replication".
What is the best way to handle this in AlterRelationNode::execute() according to
project's coding rules?
1) Several MODIFY RDB$RELATIONS statements, one for each change of attributes;
2) One unconditional MODIFY which may be no-op if no attributes was changed;
3) Loop through RelationNode::clauses gathering flags for each changed attribute and then
(if needed) one MODIFY for all changed attributes.
