source§fn is_delimited_identifier_start(&self, ch: char) -> bool
fn is_delimited_identifier_start(&self, ch: char) -> bool
Determine if a character starts a quoted identifier. The default
implementation, accepting “double quoted” ids is both ANSI-compliant
and appropriate for most dialects (with the notable exception of
MySQL, MS SQL, and sqlite). You can accept one of characters listed
in
Word::matching_end_quote
heresource§fn is_identifier_start(&self, ch: char) -> bool
fn is_identifier_start(&self, ch: char) -> bool
Determine if a character is a valid start character for an unquoted identifier
source§fn is_identifier_part(&self, ch: char) -> bool
fn is_identifier_part(&self, ch: char) -> bool
Determine if a character is a valid unquoted identifier character
source§fn supports_filter_during_aggregation(&self) -> bool
fn supports_filter_during_aggregation(&self) -> bool
Does the dialect support
FILTER (WHERE expr)
for aggregate queries?source§fn is_proper_identifier_inside_quotes(&self, _chars: Peekable<Chars<'_>>) -> bool
fn is_proper_identifier_inside_quotes(&self, _chars: Peekable<Chars<'_>>) -> bool
Determine if quoted characters are proper for identifier
source§fn supports_within_after_array_aggregation(&self) -> bool
fn supports_within_after_array_aggregation(&self) -> bool
Returns true if the dialect supports
ARRAY_AGG() [WITHIN GROUP (ORDER BY)]
expressions.
Otherwise, the dialect should expect an ORDER BY
without the WITHIN GROUP
clause, e.g. ANSI
