The buildSql is mode where you type a HiveQL select (inCallStmt is similar but with the added EXEC command + sql string). If we are in these modes the identifier is likely a table column or an aggregate func within a HiveQL. We don't need to execute the function in this case. Otherwise we try to interpret it as a function call, if that fails we throw an undef error. I think the first exec is not needed here. -- This is an automated message from the Apache Git Service.

For example it seems that > arity of a function is not checked when calling it, and same is true for > parameter types. Calling an undefined function is evaluated to null and > sometimes it seems that incorrect syntax is silently ignored. > In cases like this a helpful error message would be expected, thought we > should also consider how PL/SQL works and maintain compatibility. -- This message was sent by Atlassian Jira (v8.3.4#803005)
