String Type

Fixed: A fixed length database field contains values that are all the same length. The size of the field (String Length, in bytes) cannot vary. If an input index value contains fewer characters than the String Length, Content Manager OnDemand adds one or more blank characters to the right of the index value to fill the database field. The additional blank characters become part of the field value.
Variable: A variable length database field can contain values that are different lengths. The size of the field can vary, up to a maximum value (String Length, in bytes).
