I'm new to SAS and I'm using the PROC SQL functionality. I can not understand which is the sql language used in the PROC SQL.
It seems similar to Oracle-Sql but some functions are not available.
Can anyone clarify this point?
PROC SQL supports the ANSI SQL definition from 1992. You can also use most SAS functions.
International Organization for Standardization (ISO): Database SQL. Document ISO/IEC 9075:1992. Also, as American National Standards Institute (ANSI) Document ANSI X3.135-1992
