ROWID
The ROWID returns the rowid (binary address) of a row in the database table. You can use the variables of the type UROWID to store rowids in a readable format. In the illustration below, you declare a variable named row_id for that reason:

row_id UROWID;
Whenever you select or fetch a rowid into a UROWID variable, you can use the function ROWIDTOCHAR that converts the binary value to an 18-byte character string.
