Consider the SQL below: SELECT * FROM (SELECT ROWNUM rownum, column1, column2, upto columnN FROM DATA_TABLE) WHERE rownum > ( SELECT (MAX(ROWNUM)-10) FROM DATA_TABLE); Fetching last record from a table I was wondering if there is some possible way that I can fetch the last record from a table. the ROWNUM will apply before the ORDER BY, so that will not work in oracle.
