7.16. ODPI-C Structure dpiJsonObject

This structure is used for passing JSON objects to and from the database.

uint32_t dpiJsonObject.numFields

Specifies the number of fields that are found in the JSON object. This also identifies the number of elements in each of the remaining arrays.

char **dpiJsonObject.fieldNames

Specifies an array of field names that are found in the JSON object. Each element is a byte string encoded in UTF-8. The length of each byte string is found in the fieldNameLengths member.

uint32_t *dpiJsonObject.fieldNameLengths

Specifies an array of lengths for the names of the fields found in the JSON object.

dpiJsonNode *dpiJsonObject.fields

Specifies an array of JSON nodes that are the values of the fields found in the JSON object. Each of these is a structure of type dpiJsonNode.

dpiDataBuffer *dpiJsonObject.fieldValues

Specifies an array of buffers that contain the data for the values of the fields found in the JSON object. This member should not be used directly. Instead, the dpiJsonNode.value member of the corresponding node in the member fields should be used.
