dev.frostlake.executor.MultiStatementFailure

All Implemented Interfaces:

Serializable

public final class MultiStatementFailure
extends RuntimeException

What a request carrying SEVERAL statements answers when one of them fails while running.

The account runs such a request through a helper of its own, and a failure inside it comes back naming the statement that failed and where it sits — its own text, its line, and its column within that line — with the statement's own error carried inside. The helper's name and its internal stack are part of the sentence the account produces, so they are part of this one too: a client that matches on the account's wording sees the same text here.

Only a failure DURING EXECUTION is spelled this way. A script whose text will not parse is refused as a whole before any of it runs, with an ordinary syntax error that names no statement, and a request carrying a single statement answers with that statement's own error unadorned.
