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}
