James Taylor commented on PHOENIX-1663:
---------------------------------------
[~naveenmadhire] - please create a subtask JIRA from this one for the specific
string built-in function you'd like to implement. This JIRA is a grouping JIRA
for *all* unimplemented string functions. How about the INSTR function from
Oracle (SQL server calls it CHARINDEX and Postgres calls it POSITION) ? Once
you create that, I'll assign it to you.
