    Description copied from interface: SqlNodeToRexConverter
    
    Converts a SqlCall to a RexNode expression.
    
    Specified by:
    
    convertCall in interface SqlNodeToRexConverter
  - convertInterval
```
public RexLiteral convertInterval(SqlRexContext cx,
                                  SqlIntervalQualifier intervalQualifier)
```
    Description copied from interface: SqlNodeToRexConverter
    
    Converts a SQL Interval Qualifier to a REX literal.
    
    Specified by:
    
    convertInterval in interface SqlNodeToRexConverter
  - convertLiteral
```
public RexNode convertLiteral(SqlRexContext cx,
                              SqlLiteral literal)
```
    Description copied from interface: SqlNodeToRexConverter
    
    Converts a SQL literal to a REX literal.
    The result is RexNode, not RexLiteral because if the literal is NULL (or the boolean Unknown value), we make a CAST(NULL AS type) expression.
