| Property | in TSV | in Azure SQL |
|---|---|---|
| port | — | 1433 |
| identifiers | Rarely used, which is exactly why tabs in data break it | [square brackets] |
| row limit | — | SELECT TOP n |
| dates | Conventional text: 2026-09-18 or 2026-09-18 14:30:00 | datetime2, date, time |
| long text | — | nvarchar(max) |
| binary | Not supported - must be encoded | varbinary(max) |
