> Project: Flink

> Fix For: 1.13.0

>
> Both FLIP-136 and FLIP-129 assume that a table schema is able to store both a
> SQL expression and a Table API one. Therefore we should introduce an
> expression in Table API that allows to use SQL expressions. This is also
> useful for other use cases where people prefer SQL expressions in Table API.
> An expression `callSql(String)` next to `call(udf)` can offer scalar
> operations such as:
> {code}
> table.select(callSql("1+1"), 12, call(Udf.class, $("f0")))
> {code}
