positive.code: * _precision_ specifies the allowed number of decimal digits.
  
  
  1. The size of a column that allows null values is 2 bytes larger than the size for the defined data type.
  2.  The maximum row size is 32708 bytes, but the actual row size is less than that because of bytes used by
  null indicators, varchar column length indicators, and actual data encoding.
  3.  Storage size is the same as that required by CHAR data type but store only half as many characters depending
