Nonstandard SQL
Oracle provides extensions to the standard SQL database language with integrity enhancement. The Federal Information Processing Standard for SQL (FIPS 127-2) requires vendors to supply a method for identifying SQL statements that use such extensions. You can identify or flag Oracle extensions in interactive SQL, the Oracle precompilers, or SQL*Module by using the FIPS flagger.
If you are concerned with the portability of your applications to other implementations of SQL, then use the FIPS flagger.
