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

fn supports_filter_during_aggregation(&self) -> bool
Does the dialect support
FILTER (WHERE expr)
for aggregate queries?source§fn supports_group_by_expr(&self) -> bool
fn supports_group_by_expr(&self) -> bool
Returns true if the dialects supports
group sets, roll up, or cube
expressions.source§fn supports_lambda_functions(&self) -> bool
fn supports_lambda_functions(&self) -> bool
Returns true if the dialect supports lambda functions, for example: Read more
source§fn supports_select_wildcard_except(&self) -> bool
fn supports_select_wildcard_except(&self) -> bool
Returns true if the dialect supports an
EXCEPT
clause following a
wildcard in a select list. Read moresource§fn identifier_quote_style(&self, _identifier: &str) -> Option<char>
fn identifier_quote_style(&self, _identifier: &str) -> Option<char>
Return the character used to quote identifiers.

&self,
_chars: Peekable<Chars<'_>>
) -> bool
fn is_proper_identifier_inside_quotes( &self, _chars: Peekable<Chars<'_>> ) -> bool

source§fn supports_window_clause_named_window_reference(&self) -> bool
fn supports_window_clause_named_window_reference(&self) -> bool
Returns true if the dialect supports referencing another named window
within a window clause declaration. Read more
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

fn supports_named_fn_args_with_eq_operator(&self) -> bool
Returns true if the dialect supports named arguments of the form FUN(a = ‘1’, b = ‘2’).
source§fn supports_numeric_prefix(&self) -> bool
fn supports_numeric_prefix(&self) -> bool
Returns true if the dialect supports identifiers starting with a numeric
prefix such as tables named:
59901_user_login
source§fn supports_window_function_null_treatment_arg(&self) -> bool
fn supports_window_function_null_treatment_arg(&self) -> bool
Returns true if the dialects supports specifying null treatment
as part of a window function’s parameter list. As opposed
to after the parameter list.
i.e The following syntax returns true Read more

CONVERT(varchar, 1)
source§fn supports_triple_quoted_string(&self) -> bool
fn supports_triple_quoted_string(&self) -> bool
Returns true if the dialect supports triple quoted string
e.g.
