[jira] [Commented] (CALCITE-1457) Parser keyword conflict with UDF(insert, left, etc.)

    [ https://issues.apache.org/jira/browse/CALCITE-1457?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15590584#comment-15590584 ] 

Baofeng Zhang commented on CALCITE-1457:
----------------------------------------

I got it, just add the function name under "NonReservedKeyWord", so that UDF works.

> Hi guys, 
> I try to implement MySQL function like INSERT(str, pos, len, newts), LEFT(str, len), but these functions have the same keyword defined in Parser.jj, which leads to mistake during sql parser procedure.
> Can anyone help me to get around this? Thx!
