Thank you very much。 best qianjin > Add the JSON_TYPE function > -------------------------- > > Key: CALCITE-2791 > URL: https://issues.apache.org/jira/browse/CALCITE-2791 > Project: Calcite > Issue Type: Improvement > Components: core > Reporter: xuqianjin > Assignee: Julian Hyde > Priority: Major > Labels: https://github.com/apache/calcite/pull/1013 > > The data in json can be =, <, <=, >, >=, <>,! =, and <=>. But the data types > in json can be diverse, so when you compare different types, you have a > priority, and the high priority is greater than the low priority (you can > view the types with the JSON_TYPE() function). The priorities are as follows: > BOOLEAN > ARRAY > OBJECT > STRING > INTEGER > LONG > DOUBLE > NULL -- This message was sent by Atlassian JIRA (v7.6.3#76005)
