Example:
SELECT LIST(EmployeeID) FROM Employees GROUP BY DepartmentID sa_split_list system procedureTakes a string of values, separated by a delimiter, and returns a set of rows—one row for each value.
sa_split_list( str [, delim ] [, maxlen ])
Result set:
line_num Sequential number for the row.
row_value Value from the string, truncated to maxlen if required. |
