ryanschneider opened a new issue, #1972: URL: https://github.com/apache/datafusion-sqlparser-rs/issues/1972
DuckDB supports excluding columns via this syntax: ``` SELECT COLUMNS(* EXCLUDE(col1, col2)) FROM tbl ``` Currently this format gives a syntax error: ``` Parse error: sql parser error: Expected: ), found: EXCLUDE at Line: 1, Column: 18 ``` More details at: https://duckdb.org/docs/stable/sql/expressions/star.html#columns-expression Note that other modifiers beyond `EXCLUDE` are supported, such as `REPLACE`, `RENAME`, `LIKE` etc, see the syntax diagram at https://duckdb.org/docs/stable/sql/query_syntax/select.html#syntax (click `star-options` on the digram to expand). This highly suggests that the general solution for this would be to add a new `Expr::Columns` expression enum with parsing logic somewhat similiar to `Expr::MatchAgainst`, and then add logic in `parse_select_item` to support returning a `SelectItem::UnnamedExpr(Expr::Columns)`. -- This is an automated message from the Apache Git Service.
