             Summary: Hana translator: incorrect pushdown of QUARTER function
                 Key: TEIID-4223
                 URL: https://issues.jboss.org/browse/TEIID-4223
             Project: Teiid
          Issue Type: Bug
          Components: Misc. Connectors
    Affects Versions: 8.12.5
            Reporter: Jan Stastny
            Assignee: Steven Hawkins


Teiid's QUARTER function returns integer.
SAP HANA's QUARTER function returns string in form:
{code:plain}
2000-Q1
{code}
So the function either shouldn't be pushed down, or it has to be pushed down together with some substring method wrapping it:
{code:sql}
SUBSTR_REGEXPR('[[:digit:]]{4}\-Q([[:digit:]]{1})' IN quarter(datevalue) GROUP 1)
{code}
