Takes a JSON document and extracts a JSON array of scalar values to SQL ARRAY(TEXT) value. For JSON strings, removes the outermost quotes and unescapes the values. Other JSON scalars are not changed. Returns a SQL NULL if a non-array is given, or non-scalar value is given (inside the array). This function pairs with the JSON_EXTRACT function, which doesn’t convert the JSON values to SQL values.

​
Syntax

JSON_VALUE_ARRAY(<json>)

​
Parameters

ParameterDescriptionSupported input types
<json>The JSON document.TEXT

Return Type

ARRAY(TEXT)
  • If any of the input is NULL the output is NULL (propagates nulls).

​
Example

For the JSON document indicated by <json_common_example> below, see JSON common example. The returned result is based on this example. 
SELECT JSON_VALUE_ARRAY(JSON_POINTER_EXTRACT(<json_common_example>, '/value/uid')), JSON_POINTER_EXTRACT(<json_common_example>, '/value/uid')
Returns: NULL, '"987654"' 
SELECT JSON_VALUE_ARRAY(JSON_POINTER_EXTRACT(<json_common_example>,'/value/keywords'))
Returns: {'insanely','fast','analytics'} 
SELECT JSON_VALUE_ARRAY(NULL)
