JSON_SHRED_BATCH and JSON_SHRED_BATCH_U are SQL stored procedures that use any number of JSON instances to populate existing tables, providing a flexible form of loading data from the JSON format into a relational model. Two shred procedures are provided; however, the only difference between them is the character set of the data. To explain the functionality, we only describe JSON_SHRED_BATCH (the version that operates on LATIN character set data), but the explanation applies equally to JSON_SHRED_BATCH_U (the UNICODE version).
The batch shredding procedures map into a number of successive calls to JSON_TABLE to create a conglomerate temporary table, the values of which can be assigned to existing tables.
| Condition | Return Value |
|---|---|
| Shred operation succeeds. | 0 |
| Shred operation fails. | Nonzero value indicating specific error condition and appropriate error message |
