What a Token is.

Variants

Eof

End of input. Always the last token; text is empty.

Identifier

Sales, MyVar, NORM.DIST — internal dots are absorbed.

QuotedTable

'Sales Header' — a single-quoted table name, '' as the escape.

BracketName

[Net Price] — a bracketed column, measure, or hierarchy-level name. The lexer cannot tell the three apart; resolution does.

String

"text" — a string literal, "" as the escape.

DateTime

dt"2024-01-01" — a date-time literal.

Number

1, 1.5, 1.5E+10.

QueryParameter

@Risk — a query parameter (DAX queries, not model expressions).

Comment

// …, -- …, or /* … */ — never produces a reference.

Operator

+ - * / ^ & = == <> < > <= >= && || ! => :=

OpenParen

(

CloseParen

)

OpenBrace

{

CloseBrace

}

Comma

,

Semicolon

;

Colon

:

Dot

.

Unknown

Any other character. Never fails the scan.
