Type mapping
| Value kind | in TXT | in Oracle |
|---|---|---|
| Int | 1234, or right-aligned in a fixed-width column | NUMBER(10) |
| Bigint | 9007199254740993 | NUMBER(19) |
| Decimal | 1234.56 | NUMBER(p,s) |
| Float | 1.234e+10 | BINARY_DOUBLE |
| Text | written as-is; padding depends on the chosen layout | VARCHAR2(n) |
| Long text | written as-is | CLOB |
| Date | whatever the writer chose | DATE |
| Datetime | whatever the writer chose | TIMESTAMP |
| Binary | not representable | BLOB |
| Boolean | Y / N, or 1 / 0, or TRUE / FALSE | NUMBER(1) |
Dialect differences
TXT is a file format and Oracle 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 TXT | in Oracle |
|---|---|---|
| port | — | 1521 |
| identifiers | None by convention | "double quotes" |
| row limit | — | FETCH FIRST n ROWS ONLY |
| dates | Whatever the writer produced; no convention is guaranteed | DATE, TIMESTAMP |
| long text | — | CLOB, NCLOB |
| binary | Not supported | BLOB, BFILE |
| separator | Whatever was chosen - often fixed column widths | — |
| encoding | No declaration - UTF-8 works only with a BOM | — |
| typing | None - every field is text | — |
| shape | Free form; a parser has to be told the layout | Tables of rows and columns |
| ceiling | No formal limit | — |
