[teiid-issues] [JBoss JIRA] (TEIID-5481) Evaluate JSONPATH as expression language for Json payload to table

[Steven Hawkins (Jira)]

    [ https://issues.jboss.org/browse/TEIID-5481?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13737475#comment-13737475 ] 

Steven Hawkins commented on TEIID-5481:
---------------------------------------

Beyond this for full processing, we'd need something like:

jsoncast - which could take a json and cast to one of the known types (string, boolean, decimal, or an array of those)
jsontable - which could iterate on a context item and extract columns based upon paths.

> Currently in Teiid in order to turn a JSON document to a relational structure, JSONTOXML function is used then XPATH used on it to retrieve data using XMLTABLE.
> Investigate the feasibility of using JSONPATH [1]  directly on JSON document to build a JSONTABLE construct.
