| identifiers | Rarely used, which is exactly why tabs in data break it | "double quotes" |
| row limit | — | FETCH FIRST n ROWS ONLY |
| dates | Conventional text: 2026-09-18 or 2026-09-18 14:30:00 | DATE, TIMESTAMP |
| long text | — | CLOB, NCLOB |
| binary | Not supported - must be encoded | BLOB, BFILE |
