vimko opened a new issue, #1863:
URL: https://github.com/apache/datafusion-sqlparser-rs/issues/1863
With v0.56.0 using the mysql dialect, use the `parse_sql` function to parse
`DROP INDEX idx_name ON table_demo;` or `ALTER TABLE tbl_name DROP INDEX
idx_name;` and an error occurs.
```rust
use sqlparser::dialect::MySqlDialect;
use sqlparser::parser::Parser;
fn main() {
let sql = "DROP INDEX idx_name ON table_demo;";
let dialect = MySqlDialect {}; // or AnsiDialect, or your own dialect ...
let ast = Parser::parse_sql(&dialect, sql).unwrap();
println!("AST: {:?}", ast);
}
```
Report the following error:
```
called `Result::unwrap()` on an `Err` value: ParserError("Expected: end of
statement, found: ON at Line: 1, Column: 21")
```
In the official documentation of MySQL, when deleting an index, you need to
specify the table where the index is located.
```sql
DROP INDEX index_name ON tbl_name
[algorithm_option | lock_option] ...
algorithm_option:
ALGORITHM [=] {DEFAULT | INPLACE | COPY}
lock_option:
LOCK [=] {DEFAULT | NONE | SHARED | EXCLUSIVE}
```
