The text-based format is the default storage format for JSON data. Other storage formats for JSON data include binary and universal binary formats, as described in the following pages.
JSON data can be stored inline (inside a row) or outside the row in a LOB subtable or both, depending on the syntax used to specify it:
| Syntax | Default Inline Storage | Maximum Length | LOB/Non-LOB |
|---|---|---|---|
| JSON | 4,046 bytes | 16,776,192 bytes | LOB |
| JSON(n) CHARACTER SET LATIN, where n <= 64,000 | n characters | ncharacters | Non-LOB |
| JSON(n) CHARACTER SET LATIN, where n > 64,000 | 4,096 bytes | ncharacters | LOB |
| JSON(n) CHARACTER SET LATIN INLINE LENGTH m | m characters | ncharacters | If n <= m, Non-LOB Otherwise, LOB |
| JSON(n) CHARACTER SET UNICODE, where n <= 32,000 | n characters | n characters | Non-LOB |
| JSON(n) CHARACTER SET UNICODE, where n > 32,000 | 4,096 bytes | n characters | LOB |
| JSON(n) CHARACTER SET UNICODE INLINE LENGTH m | m characters | ncharacters | If n <= m, Non-LOB Otherwise, LOB |
If there is no column length specified, the default length is the maximum.
