> Teiid will return no rows when a function which is pushed down is used in a where clause.
> These queries should return few rows, but the result is empty:
> Query:
> {code}
> SELECT intkey, stringnum FROM BQT1.SmallA WHERE concat(stringkey, stringnum) = '7-17' ORDER BY intkey
> {code}
> Generated mongo command:
> {code}
> {aggregate: "smalla", pipeline: [ { $match: { _m0: "7-17" } }, { $project: { c_0: "$INTKEY", c_1: "$STRINGNUM" } }, { $sort: { c_0: 1 } } ] }
> {code}
> Query:
> {code}
> select intKey from bqt1.smalla where intKey+intKey >20
> {code}
> Generated mongo command:
> {code}
> {aggregate: "smalla", pipeline: [ { $match: { _m0: { $gt: 20 } } }, { $project: { _m1: "$INTKEY" } } ] }
> {code}
