This example shows how to use the JSONExtractValue method to return multiple results. This query gets the name of any school that has a type with a value like 'college'.

JSONExtractLargeValue can be substituted for JSONExtractValue.
SELECT eno, edata.JSONExtractValue('$..schools[?(@.type == "college")].name') 
FROM my_table 
ORDER BY 1;

Result:

ENO edata.JSONExtractValue(…)
