Description

Arithmetic and logical operations between different operands are usual in SQL queries. Function invocations with parameters which are different to the parameters of function definition are also usual. Implicit type conversion should occur in such cases.

Currently, however, Tajo does not support implicit type conversion. We should implement this feature.
