Dialect differences
TSV is a file format and DB2 is a database server, so the target has to be told the types the file never carried - the rows below are where the two sides diverge.
| Property | in TSV | in DB2 |
|---|---|---|
| port | — | 50000 |
| identifiers | Rarely used, which is exactly why tabs in data break it | "double quotes" |
| row limit | — | FETCH FIRST n ROWS |
| dates | Conventional text: 2026-09-18 or 2026-09-18 14:30:00 | DATE, TIME, TIMESTAMP |
| long text | — | CLOB |
| binary | Not supported - must be encoded | BLOB |
| separator | Tab | — |
| encoding | No declaration - UTF-8 works only with a BOM | — |
| typing | None - every field is text | — |
| shape | Flat table, optional header row | Tables of rows and columns |
