LookupOrderedRows()

Returns rows from a data extension sorted in ascending or descending order based on a column that you specify. If the function doesn’t find the search values that you specify, it returns an empty rowset. This function is case-insensitive.

AMPscript includes several variations of the LookupOrderedRows() function.

• The LookupOrderedRowsCS() function is a case-sensitive version of this function.
• The LookupRows() function returns unordered rows.
• The LookupRowsCS() function is a case-sensitive version of LookupRows().

The LookupOrderedRows() function has five parameters.

• dataExt (string): Required. The name of the data extension that contains the data that you want to retrieve.
• numRows (number): Required. The number of rows to return. If you specify a value less than 1, the function returns all rows, up to a maximum of 2,000 rows.
• sortColumn (string): Required. The column to sort data by, followed by a space and either ASC for ascending order or DESC for descending. This value is case-insensitive.
• searchColumn1 (string): Required. The name of the column to search. This value is case-insensitive.
• searchValue1 (string): Required. The value in the specified column that identifies the rows to retrieve. This value is case-insensitive.

You can optionally append additional search columns and values to the end of the parameter string.

This example uses a data extension called "Administrative Divisions of Canada," which contains the data in this table.
