final class SqlKeywordSequence

Finds where a run of keywords was written, at the level of the statement itself.

A clause is opened by words that only mean what they say when the statement itself says them: an ORDER BY inside a subquery orders the subquery, not the statement around it. Only a run written entirely outside parentheses counts.

Methods§

    list<SqlToken> $tokens,
