    Description copied from class: SqlOperator
    
    Writes a SQL representation of a call to this operator to a writer, including parentheses if the operators on either side are of greater precedence.
    The default implementation of this method delegates to SqlSyntax.unparse(org.apache.calcite.sql.SqlWriter, org.apache.calcite.sql.SqlOperator, org.apache.calcite.sql.SqlCall, int, int).
    
    Overrides:
    
    unparse in class SqlOperator
  - createCall
```
public SqlCall createCall(SqlLiteral functionQualifier,
                          SqlParserPos pos,
                          SqlNode... operands)
```
    Description copied from class: SqlOperator
    
    Creates a call to this operand with an array of operands.
    The position of the resulting call is the union of the pos and the positions of all of the operands.
    
    Overrides:
    
    createCall in class SqlOperator
    
    Parameters:
    
    functionQualifier - function qualifier (e.g. "DISTINCT"), may be
    
    pos - parser position of the identifier of the call
    
    operands - array of operands
