             Summary: Add native-query functionality to pushdown functions
                 Key: TEIID-2572
                 URL: https://issues.jboss.org/browse/TEIID-2572
             Project: Teiid
          Issue Type: Enhancement
          Components: Connector API
            Reporter: Steven Hawkins
            Assignee: Steven Hawkins
             Fix For: 8.5

Source functions should also support the parameterized native-query extension property to easily add calls that use non-standard or mapped function syntax.  

For an operator like pg bit shift left:

{code}
create foreign function bsl (arg1 integer, arg2 integer) returns integer OPTIONS ("teiid_rel:native-query" '$1 << $2')
{code}

For an oracle sequence:

{code}
create foreign function seq_nextval () returns integer OPTIONS ("teiid_rel:native-query" 'seq.nextval')
{code}
