Teiid would not return rows when a function which is pushed down is used in a where clause against MongoDB. This was because , the $match phase was being added correctly but it was not implicit adding the functions to $project. To rectify this, functions and agregate functions will not be supported in the $match phase in the MongoDB. They need to be pushed as projected columns, so that it can then do a $match on the computed value.

Description of problem: 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: SELECT intkey, stringnum FROM BQT1.SmallA WHERE concat(stringkey, stringnum) = '7-17' ORDER BY intkey Generated mongo command: {aggregate: "smalla", pipeline: [ { $match: { _m0: "7-17" } }, { $project: { c_0: "$INTKEY", c_1: "$STRINGNUM" } }, { $sort: { c_0: 1 } } ] } Query: select intKey from bqt1.smalla where intKey+intKey >20 Generated mongo command: {aggregate: "smalla", pipeline: [ { $match: { _m0: { $gt: 20 } } }, { $project: { _m1: "$INTKEY" } } ] }
