Parameter Attributes Description
OrderBy_Expression Optional

An expression used to determine the sort order.

OrderBy_Direction Optional

Specifies how to sort OrderBy_ColumnName values. It is a two-part value of the form OrderDirection [BlankHandling].

OrderDirection specifies how to sort orderBy_expression values (i.e. ascending or descending). Valid values include:

  • DESC. Alternative value: 0(zero)/FALSE. Sorts in descending order of values of OrderBy_ColumnName.
  • ASC. Alternative value: 1/TRUE. Sorts in ascending order of values of OrderBy_ColumnName . This is the default value if OrderBy_Direction is omitted.

BlankHandling part is optional. It specifies how blanks are ordered. Valid values include:

  • BLANKS DEFAULT. This is the default value. The behavior for numerical values is blank values are ordered between zero and negative values. The behavior for strings is blank values are ordered before all strings, including empty strings.
  • BLANKS FIRST. Blanks are always ordered on the beginning, regardless of ascending or descending sorting order.
  • BLANKS LAST. Blanks are always ordered on the end, regardless of ascending or descending sorting order.
