Syntax
ROWNUM
See Also
PSEUDO COLUMNS, INSERT, SELECT, UPDATE
Description
A Pseudo Column behaves like a table column, but is not actually stored in the table. You can select from Pseudo Columns, but they cannot be updated. Pseudo Columns provide extra information about a SELECT row set.
The ROWNUM Pseudo Column will return a number indicating the order in which the rows are selected from the table.
Example
// Display all overdue accounts with 15% commission in // Sorted "name" and "paid date" order with the row number. EXEC SQL SELECT ROWNUM, name, address, balance, cost*1.15 FROM accounts WHERE paid_date < date() ORDER BY name, paid_date;
