auto add backquote for database name.

In some case, database name include some character (like my-db), in that situation I rigth cilck table name and cilck "select Top 1000", a query will generate, but the database name not add backquote, then will raise Error: ER_PARSE_ERROR . so I need add backquote by myself (\`my-db\`).

can it be auto complite, thanks.

Start by reproducing the VS Code right-click table flow and the generated “select Top 1000” query described in the issue, using a database name such as `my-db`. Trace the query-generation entry point and verify that the completed query remains valid for database names containing hyphens.
