Dialect differences
JSON 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.

|---|---|---|
| port | — | 1521 |
| identifiers | Double quotes; backslash escapes | "double quotes" |
| row limit | — | FETCH FIRST n ROWS ONLY |
| dates | No date type: dates arrive as strings and the reader must p... | DATE, TIMESTAMP |
| long text | — | CLOB, NCLOB |
| binary | Not supported natively - base64 inside a string | BLOB, BFILE |
| separator | Braces and commas | — |
| encoding | UTF-8 by definition | — |
| typing | string, number, boolean, null, object, array - no date type | — |
| shape | Nested objects and arrays | Tables of rows and columns |
