Description

Here is the situation:

when I create two SqlBasicCalls, one uses UNARY_MINUS operator and the other uses MINUS operator. But their operandList is the same. However, The result after calling their equalsDeep() method is true.

I found that the sqlKind of many operators is reused, and the name is not guaranteed to be unique. Only the combination of kind and name can determine the unique operator.
